WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
Rear axle housing lubricant leaks usually occur at the following locations:
- Drain Plug
- Fill Plug
Drain and fill plug leaks are usually caused by a loose plug. These leaks can be repaired by either tightening the plug or by using an approved sealer on the threads on the plug.
Other leaks such as axle tube to differential carrier housing or porosity leaks require the replacement of the rear axle housing.
