So while running my kit at the track yesterday I crashed like 10 times, nothing spectacular but flipped a few times and nose dived into the opposite side of a few jumps. Sooo today I decided to rip it apart and make sure everything held up good. Have everything apart and so far I've disassembled both the front and center diff. The front diff wasn't bad at all, just a tad low, but the center diff was almost on E. Both look fine inside, no metal shavings or anything. Haven't gotten to the rear diff yet but already know its been leaking a little like the front. This is an Associated RC 8.2 FT. Question is what can I do to keep my center diff from leaking if by some chance taking it apart and refilling it doesn't somehow solve the issue? I'd rather not have to tear down the center diff after every track day. Thanks in advance for any help.
