Clearance between Front Axle and Front Gear Case
1. Assemble the front axle (1) and 43T gear (4) and related parts
with "standard" thickness of shims (5) and (6) or "original" shims
(5) and (6).
2. Use thick grease to attach the solder strips to three evenly
spaced points on the face of the shim (5).
3. Assemble the front axle cover (2) and front gear case (3).
4. Remove the front axle cover (2) from front gear case (3) and
determine the average thickness of the solder strips with an
outside micrometer.
5. If the clearance is not within the factory specifications, adjust
with shim (5).
IMPORTANT
• Do not change the overall thickness of these shims during
the next step (backlash between 9T bevel gear and 43T
bevel gear).
