Door Hardware Lubrication
WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
The mechanical components of the door are lubricated during assembly. If additional lubrication is required to any door hardware mechanism, lubricate with Superlube GM P/N 12346241 or Canadian P/N 10953474 or equivalent. Lubrication of the door hinge roller is not recommended. Lubricating the door hinge roller may allow the door hinge roller to slide against the door check link contacting surfaces causing uneven wear to the door hinge roller.
