Review on Moog RK620010 Control Joint Assembly by Phillip Jaylon

I first bought an 'upgraded' version of this part that Moog calls the 'problem solver'. It has a redesigned rear hub that includes a swivel instead of a rubber hub. It's supposed to last longer, which is probably because the original rubber bushings are prone to cracking. Unfortunately, the troubleshooter created a new problem by rattling when going over bumps, even when new. After about 3000 miles it got worse so I replaced it with one of the original rubber bushed control arms. The problem is solved! The picture shows a "Problem Solver" type control arm bushing (above) and this one (below).
