I just got a sliding balljoint camber kit for my 93 Integra. The instructions say to press out the old balljoint and press in the kit back into the upper control arm. Got to reading my Haynes manual and it says that you cannot replace the upper balljoint, you have to get a new upper control arm. Do I really need to get a new upper control arm? Don't know what to do, need to put camber kit in ASAP!
