Differential Gear Assembly
1. Remove the differential bearing holder (1), noting the number of
shims L (4).
2. Remove the differential gear as an assembly and the shims R
(3).
(When reassembling)
• Install same number of shims as before disassembling.
IMPORTANT
• Adjust the backlash and the tooth contact after assembling
the differential gear assembly. (See page 3-S73).
(Reference)
• Increase the shim R (3) thickness until to get backlash between
hypoid pinion and hypoid ring gear (2). After that adjust the
correct backlash with the shim L (4) and the shim R (3).
• Thickness of shims L:
0.4 mm (0.016 in.)
0.5 mm (0.020 in.)
0.6 mm (0.024 in.)
0.7 mm (0.028 in.)
0.8 mm (0.031 in.)
0.9 mm (0.035 in.)
1.0 mm (0.039 in.)
1.2 mm (0.047 in.)
1.4 mm (0.055 in.)
• Thickness of shims R:
1.4 mm (0.055 in.)
1.5 mm (0.059 in.)
1.6 mm (0.063 in.)
1.7 mm (0.067 in.)
1.8 mm (0.071 in.)
1.9 mm (0.075 in.)
(1) Bearing Holder
(2) Hypoid Ring Gear
Hypoid Ring Gear
1. Remove the bearing (1) with special use puller set.
2. Loosen and remove the UBS screws (3), then remove the
hypoid ring gear (2).
NOTE
• When loosening and tightening the UBS screws (3), use a
hexagonal socket wrench to protect the screw heads from
damage.
(When reassembling)
• Apply liquid lock (Three Bond 1372D or equivalent) to the UBS
screws, and tighten diagonally them with correct tightening
torque.
