Axle Shaft: Testing and Inspection
1. Inspect the front wheel halfshaft joint boots for evidence of cracks, tears, or splits.
NOTE:
-
Constant velocity (CV) front wheel halfshaft joints should not be replaced unless disassembly and inspection reveals unusual wear.
-
While inspecting the front wheel halfshaft joint boots, watch for indentations ("dimples") in the boot convolutions. Indentation must be
removed.
2. Inspect the underbody for any indication of grease splatter near the front wheel halfshaft joint boots, outboard and inboard locations. This is an
indication of front wheel halfshaft joint boot and/or front wheel halfshaft joint boot clamp damage.
3. Inspect for inboard front wheel halfshaft joint stub shaft pilot bearing housing seal leakage at the inboard front wheel halfshaft joint.
