    • How To Car Steering?Anything and Everything You Need toKnow When It Comes to Car Steering http://www.buyautoparts.com/
    • What is a Rack and Pinion?• The rack and pinion is the assembly in a vehicle that rotates the wheels from side to side when the driver turns the steering wheel. This set up is usually found in lighter vehicles and will be replaced by a steering gear box in heavier applications. This is due to the gearboxs ability to handle the increased stress due to the weight. The rack and pinion consists of a main body which houses the rack piston, a notched rod which moved left and right when pushed by the power steering fluid. The rack is controlled by the input shaft or steering column which transfers the drivers input from the steering wheel the rack assembly. A replacement rack will generally be sold with the inner tie rods and boots already attached.• A rack and pinion may be blamed for many steering issues but many times it is not the culprit. When a vehicle is hard to turn in one direction or if it is leaking it may be the rack at fault. Many times the blame for all around tight steering is put on the rack when most likely the steering pump is failing. Leaks are also miss- diagnosed often since the rack is at the bottom of the car any leak will run down to the rack. Before replacing a rack be sure to have a licensed mechanic inspect the vehicle. Knowing the true source of a leak or failure is key to avoid unnecessary auto repairs.• Source; http://www.buyautoparts.com/howto/what- is-a-rack-and-pinion.htm
    • What is a Steering Gearbox?• The steering gearbox is a unit that can be found on most of the larger duty trucks and older cars. Gearboxes are used in cases there the weight of the vehicle would be too much for a rack and pinion to handle. As the materials that are used in the building of vehicles have become more and more advanced the need for a gear box instead of a rack is fading. The gearbox is the unit that is used to transfer the rotational input from the steering wheel into directional movement of the wheels. The input shaft attaches to the steering column and transfers the drivers inputs into the gears which react to move the tires in the desired direction.• Source; http://www.buyautoparts.com/how to/what-is-a-steering-gear-box.htm
    • What is Active Steering?• Active steering first appeared in the BMW 5 series in 2003. According to BMW, “Active Steering offers precision, agility, and comfort in every driving situation.” What does that mean for the driver? It means that active steering will enhance your car’s driving performance when you are driving in city traffic, when you are parking your car, or when you are turning through a sharp curve. When you are driving at lower speeds the steering ratio becomes more direct, meaning that the wheels will turn more with less effort. At higher speeds the Active Steering system adjusts the ratio to become less direct. As a result the wheels are less responsive to small steering adjustments. This prevents oversteering at high speeds when it could potentially threaten the stability of your car.• How does active steering work? At the heart of the Active Steering system is the planetary gear set that is integrated into the steering column. There is a motor in the joint that adjusts the front wheel’s steering angle. A speed sensor passes information to the Active Steering system so that the front wheels can be adjusted according to the speed that you are traveling.• Remember our blog on Electronic Stability Control? Well, Active Steering and ESC work together in most modern cars. If the Electronic Stability Control system senses that the vehicle is becoming unstable at any point while you are driving, ESC sends a message to Active Steering to help the vehicle regain stability. If your vehicle experiences an unsafe yaw, Active Steering can almost instantly increase the angle of the steering wheels. It can do this, “faster than even the most expert driver.”• The point of Active Steering is to increase the safety of your vehicle. At no point does Active Steering interrupt the direct connection between the steering wheel and the front wheels. Even if there is total electronic failure in your car, the driver will always be able to maintain control. At the first sign of trouble, an adaptation mechanism shuts off Active Steering by locking the ring gear of the planetary gear set, which makes the gear set a fixed ratio. If there is ever a problem inside the planetary gear set, there is an alternate shaft that runs from the steering wheel shaft to the steering rack that gives the driver the ability to implement conventional steering.• Source; http://www.buyautoparts.com/howto/what-is-active-steering.htm

    • How to Center A Gear Box?• When installing a new power steering gearbox there are a few crucial steps that need to be followed in order to have a successful installation. Before installing a gearbox, it is important that the unit is centered. Many mechanics will assume that the unit is centered when it arrives, however usually it is not. Gearboxes can shift in transit, causing it to be misaligned. In order to center the unit before the install, follow these easy steps:• 1) Place the unit where it can be braced down and cannot move or fall.• 2) Cover the spline with a cloth to prevent damaging the splines during the centering procedure.• 3) Attach a wrench to the input shaft and turn until it stops. (never force the unit) This will be the extreme for this direction. (for this install turn clockwise first)• 4) Once the unit is at extreme clockwise rotation, mark the unit or move the wrench to a position where the number of return rotations can be counted easily.• 5) With this position marked, begin to rotate the shaft back clockwise and count the number of rotations. Be exact on this! Once the rotation stops clockwise, the complete rotations for the unit are known.• 6) Divide the number of rotations in half and rotate the shaft that many turns back. At that point, the gearbox will be centered and can be marked for center, so that the center is not lost during the install.• 7) Once the box is centered, follow the proper procedure for the gearbox installation.• When these short steps are followed carefully, the gearbox will be centered and there should be no issues with the vehicle’s steering.• Source: http://www.buyautoparts.com/howto/center-steering-gearbox.htm
    • Honda Accord Steering Moan• The 2003 - 2007 Honda accord is a great car but even the best have some issues. The Accord is well known for having a moaning or screeching issue when in full lock and this is caused by bad O-rings allowing air to enter the steering system. The fix for this is simple and can save the vehicle owner a number of future headaches. During cold starts after air has entered the system the cold power steering fluid can have bubbles or foam in it that will dissipate once the fluid has warmed and the noise will stop.• 1. Remove the bolt holding the inlet joint to the power steering pump housing.• 2. Place a shop towel under the inlet joint.• 3. Twist the inlet joint back and forth until it is loose, then carefully disconnect the joint and point the hose upward to minimize fluid loss.• 4. Remove the inlet joint O-ring.• 5. Apply power steering fluid to a new O-ring and install it on the inlet joint.• 6. Install the inlet joint and torque its bolt to 8 lb-ft• Top off the power steering fluid if needed. Start the engine and let it idle. Confirm that the noise is gone and that the system is operating properly.• This is a simple but helpful update due to the fact that a mis-informed mechanic may mistake this noise as a bad steering pump and the fix can be significantly more expensive.• Source; http://www.buyautoparts.com/howto/honda-accord-steering- system-moan.htm
    • How is a Steering Rack is Rebuilt?• Make no mistake there is a difference in quality. When it comes to rack and pinion the quality of the build is a major factor on the lifespan of the part. At BuyAutoParts.com we rebuild our racks to better than factory standards.• When you install a premium remanufactured rack and pinion unit, you know that it will fit and function properly. This is not your ordinary remanufactured rack and pinion unit. Every component is inspected and then remanufactured, and often replaced with new components, so the finished unit will always meet OE performance and quality standards. All rack shafts are machined to a precision OE-type finish to assure extended seal life. New seal packs are installed to assure optimum performance. For longer life, steel sleeves are installed in all domestic and import aluminum housings. Port threads are inspected and new O-rings are provided to ensure a leak-proof installation. Our work doesn’t stop until each unit passes a function test that assures smooth and quiet operation. Finally each unit is tested on a unique steering system dynamometer, and tested for pressure, flow control, valve operation, noise, and smooth power assist. Our customers tell us our racks are the best in the business!• - New seal packs are installed on every unit to ensure optimum performance• - For longer life, steel sleeves are installed in all domestic and import aluminum-style housings• - Port threads are inspected and new O-rings provided to ensure positive leak-proof installation• - Stainless steel clamps are installed• - All lines are thoroughly cleaned, pressure tested and replaced if necessary• - Shafts are centerless ground for precision OE-type finish to assure extended seal life• - Mounting bushings are included on most applications• - New premium grade bellows boots• - inner tie rods are thoroughly inspected, remanufactured or replaced if necessary• Once our remanufactured rack and pinions have met all these standards they are tested for proper operation.• Source; http://www.buyautoparts.com/howto/how-a-steering-rack-is-rebuilt.htm

    • What is a Steering Control Valve or Steering Cylinder?• Steering systems have changed over the years and each time they change new technology takes the place of the old. With new technology taking over the old begins to fail and need to be either replaced or rebuilt. When rebuilding older parts it is important to take care to that the cores these parts are based on are in good shape and the process is done correctly. Each of the units such as the steering control valve and steering cylinders need specific attention paid to them.• The steering control valves that BuyAutoParts rebuilds are not just rebuilt internally but have some extra steps to be sure of the quality.• - New OE (Original Equipment) quality seals and O-rings are installed• - New dust boots are installed on almost all units unless the boots are in perfect condition• - Ball studs are inspected and replaced if any signs of wear are apparent• - Port threads are thoroughly inspected and new tube seats are replaced if necessary• - All the threads in the unit are thoroughly inspected• The steering cylinders are inspected and rebuilt with the same level of care to be sure of a quality build.• - Ball studs are inspected and replaced if any signs of wear can be seen• - New OE (Original Equipment) quality seals and O-rings are installed• - Housings are thoroughly inspected for dents and warpage• - Port threads are thoroughly inspected and new tube seats are replaced if necessary• - All shafts are carefully inspected and replaced if any signs of wear are apparent• - All threads are on the unit are thoroughly inspected• Once the units have been inspected and rebuilt they are tested for movement and quality.• Source; http://www.buyautoparts.com/howto/how-is-a-steering- control-valve-or-steering-cylinder-rebuild-done.htm
    • How To Determine Gearbox Types?- There thousands of cars on the road nowadays andno 2 models are exactly alike. To assume that everymodel uses the same steering components wouldbe incorrect, there are 8 major box types and theneach of these will have many many variations.- Bolt VS Ring Retained Cover - this refers to what isused to hold the housing cover in place, 4 bolts or asnap ring- Ford VS Saginaw - Ford boxes will use a 2 bolthousing cover and Saginaw will use the 4 bolt coverFord VS Bendix - The differences in these 2 boxescan be seen in illustration (5)- Standard VS Reverse Rotation - which refers to therelationship of the input shaft to the output shaft-When installing a gearbox in any vehicle properunderstanding of which unit is needed is essentialto ordering the correct parts which will avoid futurecomplications.- Source;http://www.buyautoparts.com/howto/how-to-determine-gearbox-types.htm

Remove Pitman arm from steering box and relay rod. Removebolts holding original steering box and remove it from car.· Cars with Power Steering – Disconnect column coupler at steeringbox. Remove Pitman arm from steering box and relay rod. Removebolts holding original steering box and remove it from car. Removefactory ram assembly, control valve, and houses. (Once flushedclean, your original pump may be used.)· Steering Column Removal – Depending on available space andaccess to a lift you may want to remove your steering column forease of installation. Loosen or remove the bolts attaching thesteering column to dash and floor. Disconnect factory wiring fromcolumn. Slide column back and remove from the car. The column willneed to be modified to complete the installation.Installation of Corvette Steering System:Note: Manual steering Relay-Rod or Drag Link Adapter will berequired on cars with factory ram assist style power steering.Note: Slight modifications are required to original steering column.· Bolt the new steering box to the frame. Check that the front of thesteering box is not making contact with the frame, or any surroundingbrake lines. 1968-73 will require modification/relocation of brakelines and brake proportioning valve for installation. Do not grind oralter the steering box.· Connect the proper Rag Joint coupler to the new steering box. Atthis point the steering column shaft must be shortened for a properfit. Measure from the rag joint to the center of the hole on thesteering column mount, add ¾ inch to that measurement to allow forsteering shaft engagement in to rag joint. Modify column as follows:· 1963-66 Column Modification: Using the measurement from the ragjoint to the column mount, measure from the center of the mountingholes on the column to the end of the column shaft; subtract thismeasurement from the one you obtained above. You will either needto trim the column shaft this amount or mount the column furtherinto the car. Be sure to leave enough spline for rag joint if trimmingthe column shaft.· 1967-82 Column Modification: Using the measurement from the ragjoint to the column mount, measure from the center of the mountingholes on the column to the end of the column shaft; subtract thismeasurement from the one you obtained above. You will need togently tap the collapsible column shaft in to the column this amount.Do not collapse the shaft too car; it can be difficult to get it back out.- Source; http://www.buyautoparts.com/howto/instructions-for-63-82-corvette-steering-kit.htm

Then racks are painted (not shown) with high quality automotive paint.• - Bushings are checked and replaced.• - Pressure comes from and goes into the center ring. Depending on which way you are turning the pinion distributes fluid through either the top or bottom ring (small holes) which sends through to the pinion pressuring in that direction and giving the driver assist.• Source; http://www.buyautoparts.com/howto/our-steering-rack-and-pinion.htm
    • Power Steering Fluid Recommendations• Power steering fluid cools, cleans, lubricates, and conditions the seals within the power steering system. PS fluid also transmits the hydraulic force used to assist with steering. With so many requirements its no wonder there are a plethora of formulations on the market. Many vehicle manufactures utilize specialized fluid. These fluids are designed to work in specific systems and usually give the best results. If youre asking yourself "Which power steering fluid do I use" take a look at our chart above.• There are also a number of systems that use automatic transmission fluid for power steering. These systems are usually designated with the words "Use automatic transmission fluid," Use Dexron" or "Use Mercon" written on the fill cap or in the owner’s manual. Automatic transmission fluid is fine for the systems designed to work with it, but should never be used in a system that calls for power steering fluid.• Due to a huge number of factors, no guide can replace individual manufacturers recommendations. The above is a general guide but should be verified for specific makes and models. Most power steering problems involve leakage. Over time, seals get hard and debris wear away at the sealing surfaces. Both problems are made far worse by dirty power steering fluid with depleted additives. Replacing power steering fluid is very easy and will save you a big headache in the long run.• Source; http://www.buyautoparts.com/howto/ps- fluid-rec.htm
    • Power Steering Pump Types• Over the years the designs of automobiles have changed almost every time a new model is released. Knowing what parts are on your vehicle is the key to ordering the correct parts for replacement. There are 4 major types of power steering pumps that have been used and each has many variations as well.• Power steering pump types:• - Eaton• - Saginaw• - Ford• - Thompson• Each of these units is designed to meet specific needs, when replacing a pump be sure to order the correct unit to meet your vehicles requirements.• Source; http://www.buyautoparts.com/how to/power-steering-pump-types.htm
    • Power Steering Trouble Shooting Guide part 1• Make no mistake diagnosis is as important to the repair process as the parts or the installer. The steering system is one of the most commonly misdiagnosed parts of a car. Understanding how the system works and what needs to be done to fix the issue can save a vehicles owner thousands of dollars and not to mention lots of time. When a steering system has an issue most mechanics are happy to say something general "your rack is bad" but this may not always be the case. When the rack is replaced many times it will fix the issue but the reason is not that the part was bad. The reason it fixed the issue is because during the install they also replaced the parts or cleared the obstruction that was causing the issue. The chart above walks through diagnosing major and minor issues that may strike in the steering system.• Source; http://www.buyautoparts.com/howto/po wer-steering-trouble-shootong-guide.htm

    • Steering and Suspension Parts• To bleed the system, make sure the reservoir is full of P/S fluid then start the engine. Then slowly start turning the steering a quarter turn in each direction, then a half turn, etc. until you have reached the stops on both sides. Stop the engine, check fluid level in reservoir (add fluid if necessary) and note any bubbles in the fluid. If air is still present in the system let the vehicle sit for a few minutes and then repeat the process. NOTE: Some Ford units are difficult to bleed. In extreme cases a vacuum pump may be necessary to bleed all the air out of the system.• Source; http://www.buyautoparts.com/how to/steering-system-inst.html
    • Vehicle Steering Tight in Both Directions After Rack or Gearbox Install• When a steering system begins to fail, it is a good idea to take a look at all the factors. With a steering system this is a key factor in avoiding future complications, not to mention future expenses. A steering rack or gearbox may be replaced due to a number of reasons but can also reveal some pre-existing problems.• A power steering system is run by fluid that is pumped throughout and creates pressure that can assist with the directional rotation. When a new rack or gearbox is installed it may seem to be too tight or slow moving compared to the old unit. The issue here is usually not the new part. However, the new part has most likely revealed that the pump is not creating enough pressure. This tight steering is caused by the tightness of the new rack which the low pressure cannot manipulate. The old unit was broken in and easy to move, thus it could be manipulated with very little pressure from the pump. The sign of a bad pump after a steering part install is the same as before, stiff steering in both directions.• Another common issue after an install is to have a lack of power assist, and a leak from the top of the unit. This leak is not from a bad rack or gearbox but from a clogged line, which causes back pressure. A steering rack has no seal on the top and if fluid is pushed out of this area it means the fluid cannot travel back to the reservoir. This issue can be solved by replacing the lines or flushing them if possible.• The last common issue after a steering install is noise from the rack. Now, there is no such thing as noise from a rack or gearbox. The noise is traveling from another source. Inside of a rack there are no pumping parts that can create noise. Once again noise in a steering system is created by the pump and travels down the attachments to the largest point. This point is either the rack or gearbox. Even though this is where the sound can be heard it is not the source. Noise can be associated with air in the system or a failing power steering pump.• Source; http://www.buyautoparts.com/howto/steering-stiff-after-rack-or-gearbox-install.htm
