What can fail
The axle housing may not be properly manufactured, allowing axle retaining nuts to loosen and detach. This could cause the axle shaft to separate from the housing, reducing braking and vehicle stability. You may notice noise, vibration, or differential oil leaks.
What the fix does
A dealer will inspect the rear axle assembly, retighten the axle retaining nuts, remove any weld spatter, and repair or replace damaged components as needed.
