I just posted a question about rebuilding my transmission, but since these questions are for the 4-wheel-drive part of my truck, I figured it would be best to put them here. Can anyone suggest a good rebuild kit for the transfer case in my truck? It needs to be able to handle at least 350 hp. The other questions pertain to the front and rear differentials. Could I put a locking rear differential and a front limited slip differential in my truck and not sacrifice driveability? The only times I would use 4 wheel drive is in extremely inclement weather or on the beach. There may be other times that I would use it but 99% of the 4x4 time would be the previously mentioned circumstances. Also, if I just put a locking rear differential in, which one would be best in terms of quiet operation? I am considering a torsen differential. Thanks in advance.
