Default Re: Clunk on Aceleration from a stop

True, that annoying but subtle clunk from a stop. There was a "fix" for this but it still seemed to come back in some cases. There was an updated slip yoke for the shaft that was nickle plated. Problem was mostly in full size trucks but was also a problem on some early model h-2's. This was a very subtle clunk type noise and was not damaging but more of an annoying problem. All in all worth a look though. Another way to band-aid this problem was to remove the rear shaft and lube the splines of the slip yoke with a gm "special lube" similar to lithium grease but a little thicker.
