Well, I'm getting the bugs all sorted out on the new to me 7.3 F250 I picked up...now I need to address the leaking differentials. It seems easy enough, I just want to be sure to use the right fluid. Can I run straight synthetic or do I need to run some type of additive for limited slip? I would love to do the finned rear end cover, but I'm not spending money on that stuff right now. Thanks in advance for the help I'm sure you'll give me!:rockon:
