I have been trying to tighten it the same way I did on my 2wd Slash but it keeps coming loose. It's a pain having to pull the back end off every time to tighten it again especially when I'm using it during a break at work. Also anyone having problems with small rocks getting into the driveshaft chamber and chewing up the driveshaft? Mine looks like it's been on a laythe lol. Don't know how long it's going to last. I think the opening in the front is letting the sand and rocks into the chamber. Maybe there's some way to cover it?
