I have a 1999 Bravada. It has started to Thump and jerk at take off. What is the problem?

Question

Checked the transmission fluid, it is okay. Only does it for a short time, then stops.

Answer 1

Could be a CV joint going bad.   Usually from water getting into the joint from a tear or cut in the rubber protector.      Turn the wheels all the way in one direction to look at the CV boot and look for a torn rubber boot, or lots of oil leakage around one.    They are packed with lube when installed at factory or at replacement.   Water inside will kill them in no time.
