Thanks for this info, love finding a post from 2011 that's still current!

I'm new and just got my 2.0 running last night, having diff issues. I read the article and see the suggestions, but I wanted to post this anyway...

When holding the wheels and giving her some throttle, my vehicle doesn't "jump" off the ground at all-implying the diff slipper screw (nut) is too loose. However, I tighten the thing almost all the way down and nothing changes...

I see the author recommends the AE diff set as one solution to the problem, and even a spacer, but before I buy anything else I wanted to post...

Could this be something else? Maybe the actual diff screw (and not the slipper) is too loose? It's got a Gen2 R5 13.5T brushless, so should be plenty of power to get these wheels off the ground when testing for diff? I literally turned it on last night for the first time, so I haven't done much experimenting yet...

Any thoughts?

Thanks.
