Inspection and repair

1. Check the total clearance of the rear axle.
(a). Park the vehicle on flat road.
(b). Set the transmission to neutral and tighten the parking brake.
(c). Lift the vehicle and support it with safety bench.
(d). Separate the rear transmission shaft from main reducing gear. (Refer to “chapter 33
transmission shaft - transmission shaft assembly, replacement”)

(e). Rotate the flange of the main reducing gear
counterclockwise to the limit position of the side
and make matched marks on the flange and the
case of main reducing gear.

(f). Measure the total clearance of the rear axle.
The total clearance of the rear axle: ≤ 6 mm
If the total clearance of the rear axle exceeds the limit
range, then the gear clearance of the rear axle is too big,
Total
clearance of the main reducing gear must be removed to adjustment.
the rear axle
Hint:
25 Rotate the flange of the main reducing gear clockwise to
the limit position of the other side and measure the
distance between the two matched marks made on the
flange and the case of main reducing gear.This distance
is the total clearance of the rear axle.

2. Check the rear-axle housing
(a). Check whether the rear-axle housing cracks or leaks oil and weld up it if necessary.
