Inspect Axle Housing
Axle housing inspection and repairs are limited to the follow -
ing checks or repairs:
• Visually inspect axle housing for cracks, nicks and
burrs on machined surfaces.
• Check carrier bolt holes and studs for foreign mate -
rial.
• 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 re-
pair 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 gas-
ket compound (included in many repair kits). The com-
pound 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 surf aces 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.
