The document discusses three types of rear axle casings: 1) Split type which has two halves bolted together and requires removing the entire rear axle for repairs; 2) Banjo or separate carrier type which has a one-piece casing that carries the differential unit and allows removing half shafts for repairs; and 3) Salisbury or integral carrier type which is like the banjo type but has permanent housing tubes welded to the differential housing, making it the most widely used type today.

1. REAR AXLE CASING

2. REAR AXLE CASING
• It is used as casing for rear axles.
• They are classified into three types
1. Split type
2. Banjo or separate carrier type
3. Salisbury or integral carrier type

4. 1.Split type
• In this type, the axle casing is made in two halves
and then bolted together for assembly.
• This type has a major disadvantage that in case
of any fault, the whole of the rear axle has to
removed as a unit and then disassembled.
• This type is no longer produced or used.

5. 2.Banjo or separate carrier type
• This type of axle of one piece type, shaped like banjo.
• The complete differential unit is carried in a separate
carrier which is bolted to the axle casing.
• The two half shafts are put from sides.
• There fore in case of any need for repairs, the half shaft
can be taken out directly from the sides and of
differential assembly removed by opening by bolts

6. 3.Salisbury or integral carrier type
• This is similar in construction to the banjo type except
that in this the carrier.
• ie, the differential housing, has permanent housing
tubes pressed and welded in its sides.
• According to S.A.E nomenclature, it is called the
unitized carrier housing.
• This type of housing is most widely used these days in
case of rear drive cars.
