I have recently purchased a 1994 Land Cruiser and after trailering it home, have come to find out the transfer case was completely out of fluid. So after filling, driving some, and draining it and filling again, when accelerating at speeds higher than 5-10 mph, it makes noise that I can only compare to chain slap, but I don't believe these transfer cases had chains? I could be wrong though, as this is my first experience owning a Land Cruiser. I can tell the noise is not coming from the engine, as it makes no noise in neutral, and the transmission shifts fine. I also feel like when I hear the noise, I can almost feel it in the transfer case shifter. Any suggestions would be appriciated!
