Checking Tool and a torque wrench
to check differential bearings turning torque. The turning
torque should be 0.56 to 2.03 (5 to 18 in.
If the turning torque is too high, ‘install a 0.05 mm
in.) thinner shim. If the turning torque is too low , install
a 0.05 mm
in.) thicker shim. Repeat until prober
turning torque is obtained.

REAR AXLE General Information.
In the rear axle structure, the unit bearing is
fitted to the rear hub and bolted to the knuckle.
Also, the unit bearing utilizes a double row angula r
contact ball bearing.
The drive shaft has a T.J.
on the differential side and a B.J. constant-veloci ty
joint on the wheel side.
In vehicles with a
rotor for detecting the is
on the outer ring of the drive shaft B.J., and a
speed sensor is located on the knuckle.
The differential carrier provides elastic support b y,
means of a bushing. In addition, the VCU-type LSD
has been adopted in some models.
