I would find a couple of "known good" axles and swap them in and test drive it... BTW if your teg is lowered more than 1 1/2
inches you may be putting the stock length axles in a severe bind. They may not have enough depth in the inner joints to allow sufficient movement inside causing them to jam at the bottom. Makes for premature and excessive wear, broken transmission or differential or even a possibly bent axle. The solution is to raise it back up some or get custom shortened axles ( a 1/2 inch shorter axle shaft should be OK).
