Replace Front Shock Absorber

Suspension system

  1. 1. Replace Front Shock Absober
  2. 2.  Shock absorbers consists of spring which determine posture and cushioning buffer action and a damper which suppresses vibration  The shock absorber is installed between the car body and the tire, along with a spring. Elasticity of a spring damp shocks from road surface, however,it causes vehicle to vibrate due to its resilience characteristics. The part serves to damp shocks is referred to as a"shock absorber", and viscous resistance force is referred to as "damping force".
  3. 3.  Shock absorbers are a critical product that determines an automobile's character, not only by improving ride quality but also by functioning to control the attitude and stability of the vehicle  a bump stop is a rubber placed in the shock absorber piston to prevent it form bottoming out.
  4. 4.  Double-tubed shock absorber with a function as part of the surpport structure of the suspension. Like the double wishbone type, it is a shock absorber filled with low-pressure nitrogen gas that is supple and provides stable riding comfort.
  5. 5.  Structurally, this is a single-tube type placed upside down. In case of structs bears a heavy load from the vehicle body, however, this type of shock absorbers with large-diameter pipe provide sufficient rigidity.
  6. 6. Instructions Preparation 1. Park the car on a relatively level surface. 2. Loosen the wheel's lug nuts. 3. Place chucks (a rock or a wooden wedge) behind the rear tires. 4. Jack up the front of the car. Be sure to place the jack under the frame and not the suspension system. 5. Position jack stands under the car's frame. 6. Remove the wheel.
  7. 7.  Remove Old Shock  7. Loosen and remove the lower attachment bolts and nuts of the shock absorber, and remove them.  8. Grasp the shock absorber piston with a set of vice-grips.  9. Use a wrench to remove the upper attachment nut from the shock absorber piston rod.  10. Remove the old shock absorber.Replace Rubber Bushings and Grommets  11. Set the first grommet on the shock absorber piston rod with the convex side up.  12. Slide the rubber bushing on the shock absorber piston rod. Push it down until it is seated on the grommet.  13. Put the second grommet on the shock absorber piston rod with convex side down, so it seats nicely on the bushing.  14. Remove the plastic strip from around the shock, if one exists. Sometimes the factory will place one on new shocks to avoid compression during shipping.
  8. 8.  Observe your car from the front. With the car on a flat surface, it should appear perfectly level, i.e. both sides being the same height off the surface.  Push down on the front of the car to test for weak shock absorbers. This is not a scientific test and is somewhat subjective. But it can be helpful when taken in conjunction with other checks made.
  9. 9.  Visually inspect the struts or shock absorbers. Look for signs of liquid that is or has been running down the shock absorber. If present, then your shock absorbers could be bad. Once the seals begin leaking, the shock absorber becomes ineffective.
  10. 10.  Instructions  1. Push up and down vigorously on the front and then the rear of the vehicle. This is the oldest and most dependable way of checking shock performance. This may be difficult on some vehicles due to their body style and lack of protruding bumpers with which to push. The vehicle should exhibit resistance to pushing down, and when the front or rear is rocked, the vehicle should stop rocking immediately when released. If it keeps rocking, the shocks are worn out.  2. Drive the vehicle over a rough surface. If the vehicle has any amount of rocking or pitching it is a good indication of worn shocks. Drive the vehicle slow and momentarily tap the brakes. If the nose dives or rocks two or three times before coming to rest, the shocks are worn. The shocks do not support the vehicle--they just provide resistance to the up and down movement of the vehicle. If you held a shock and tried to depress it, you would find it extremely difficult. The same thing applies to trying to extend the shock.  3. Raise and support the vehicle on jack stands. Inspect the shocks for oil leaks, which indicate a bad seal. If the shocks
  11. 11.  Install the New Shock Absorber  15. Place the new shock between the upper and lower suspension arms.  16. Push the shock absorber piston rod through the hole in the upper suspension arm.  17. Tighten the upper nut onto the shock absorber piston rod.  18. Compress the shock, using slow and gradual pressure, until the bottom of the shock lines up with the mounting holes on the lower suspension arm.  19. Insert the bottom bolt through the lower mounting holes and the bottom of the shock absorber.  20. Screw in the lower nut onto the lower mounting bolt.  Finish Up  21. Replace the wheel.  22. Tighten the lug nuts onto the wheel's lugs.  23. Lower the car from the jack stands.  24. Screw in each lug nut one quarter of a turn.
