Rear Differential Knocking Sound
After looking through the forums I didn't, again, find exactly what I was looking for. Related to the rear differential, is it supposed to actually make a "locking or knocking" sound when going into reverse? Or even when shifting in 1st-5th? It's almost as if the transfer case is "free flying" when I'm off the gas and re-engages when I get on it again. As for the reverse portion, that knocking sound always comes up when going backwards as if there is a bit of "space" floating between the forward and reverse points... should I just have the transmission, transfer case, and rear differential rebuilt (was planning on doing this later)?
