Sealing Surfaces

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 GMC Sierra, 2002 Chevrolet Tahoe, and 2002 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.

Front axles components are assembled using specific sealers. A leak at a surface sealed with sealant is usually caused by a poor fit of the components but can also be caused by the use of the wrong sealant. When correcting a sealant leak, inspect each component for distortion and for nicks or gouges that may prohibit the sealant from sealing properly and when re-assembling the component, use the proper sealant.
