GM Service Manual Online
For 1990-2009 cars only

Notice: With the removal of the wheel drive shaft for any reason, the transmission sealing surface (the tripot male/female shank of the joint) should be inspected for corrosion. If corrosion is evident, the surface should be cleaned with 320 grit cloth or equivalent in a rotational motion only. Do not clean with an oscillating motion. Transmission fluid may be used to clean off any remaining debris and the joint wiped dry before installation. Corrosion on the joint sealing surface may damage the transmission seals and cause a fluid leak.
