You sure you have the fronts installed in the front and not in the rear?
the rear UJ's are slightly shorter than the fronts. Ive also had this problem before, it was a case of not being aware of the difference when i reassembled the buggy

It could also be a worn diff outdrive.

Taking out some droop may work as a temp fix.

yeah I would say the unversal is the wrong one, to tell if you have the right one in there it will have 2 round ribs in the middle of the shaft.

Yup... and when they wear out... replace them with the Kyosho ones. They last longer. As someone said though, if your diff outdrives are really worn it could cause this. I have one with a slight chip on the "corner" of the slot, and I've had that happen ONCE.

After close inspection all I can find is a chipped corner on the out drive I am going to put a new out drive and shaft some new bearings and try it again its probly time to put some fresh diff oil in anyways. Mark

The chipped outdrive will certainly cause that. Replace it and see if that resolves it.

check for slop or cracks on the arms, c-hubs and knuckle arms. Anything loose at the hingpins or kingpins could also be causing the problem. Your upperarm holding the turnbuckle could could be stripped.
