no, haven't had an issue. I'm running bellows too. 1500 miles so far. guess I need to switch to vent line extensions.
I don't know what kind of conditions the other guys been riding in but where I've been riding it's been super hot sugar sand we were having overheating problems from being so hot out probably the last four times I went riding maybe that could've had something to do with it maybe the little puddles that we did fine and went through my differential could've been so hot that I could've warped the seals I never had a problem before always ride in the same spot but it was always wet in and of water never ran that hot like I did the last few times I rode but the weird part is that all the other seals are good just the rear
But I do ride her hard and put up wet
That could have something to do with it to LoL
