Inspection
Axle housing inspection and repairs are limited to the

following checks or repairs.
• Visually inspect axle housing for cracks, nicks, and
burrs on machined surfaces.
• Check carrier bolt holes and studs for foreign

material.
• Replace damaged fasteners. Look for loose studs or
cross threaded holes.

Any damage which affects the alignment or structural integ-
rity of the housing requires housing replacement. Do not
repair by bending or straightening. This process can affect
the material's properties and cause it to fail completely
under load.
• Check all seals and gaskets.
Note: Replace conventional gaskets with silicone rubber

gasket compound (included in many repair kits). The
compound provides a more effective seal against lube
seepage and is easier to remove from mating surfaces
when replacing parts.
Inspect Components
Inspect all steel parts for:
• Notches, visible steps or grooves created by wear
• Pitting or cracking along gear contact lines
• Scuffing, deformation, or discolorations. These are
signs of excessive heat in the axle and are usually
related to low lubrication levels or improper lubrica-
tion practices.
In addition, inspect the following for damage:
• Differential gearing.
• Bearings for loose fit on drive pinion, pilot bearing,
and differential bearings.
• All fasteners for rounded heads, bends, cracks, or
damaged threads.
• Inspect machined surfaces of cast or malleable
parts. They must be free of nicks, burrs, cracks,
scoring, and wear.
• Look for elongation of drilled holes, wear on sur-
faces machined for bearing fits and nicks or burrs in
mating surfaces.
Inspect Primary Gearing
Before reusing a primary gear set, inspect teeth for signs of
excessive wear. Check tooth contact pattern for evidence of
incorrect adjustment.
