Note :
1. It is very important that the liquid gaskets listed above or their exact equivalent be used on the vehicle.
2. Be careful to use the specified amount of liquid gasket.
Follow the manufacture's instructions at all times.
3. Be absolutely sure to remove all lubricants and moisture from the connecting surfaces before applying
the liquid gasket.
The connecting surfaces must be perfectly dry.
4. LOCTITE 515 and LOCTITE 518 harden upon contact with a metal surface.
Do not apply LOCTITE 515 or LOCTITE 518 between two metal surfaces having a clearance of greater
than 0.25 mm (0.01 in). Poor adhesion will result.

REAR AXLE ASSEMBLY
GENERAL DESCRIPTION
194 mm (7.6 in)
220 mm (8.6 in)
The rear axle assembly consists of the rear axle case, the differential carrier assembly, the rear hub assembly, and
the rear axle shaft.
The rear axle assembly supports the greater part of the vehicle weight including the load. It receives the engine
torque through the clutch, the transmission, and the propeller shaft, magnifies the torque at the final gear, and
delivers the torque at a right angle to the rear axle shaft.

Install the axle shaft assembly on the opposite side and push it
in until it fits against the differential thrust block. Then,
measure the clearance (t) between the bearing holder and the
axle case flange and determine the thickness of the shim to be
installed by the following formula :
Measured clearance (t) + 0.3 mm (0.012 in) = thickness of
shim to be installed.
