R/R THS cvd keeps popping out from diff cup?

[bearster18]

on my revo 2.5 I put some THS cvds all the way around and my R/R keeps popping out all the time. Had to put it back in 3 times in one tank of gas. That's a pain the back side to keep taking the control arm loose to put it back in? Seems to sit fine in the diff cup when stationary but when out running around it pops out pretty easy. Any ideas or thoughts? All the rest of them sit in the cups like this one does and stay in.

Thanks,
Dan

Sounds like you need to get the extended drive cups.

probably so. I just used the cups that came with the CVDs

Extended cups, or trim the a-arms and sink the pivot balls deeper.

ok thank you.

second note though. I laughed out loud cause all I saw was pivot and balls deep.
