So before winter hibernation the rear shocks were horrendous. I think they only get about 50K out of them, maybe less? So might as well do the fronts too. Get it up on the lift and pull the upper arm assembly, get the strut assembly out and am like sh*t...might as well do the bushings right? Pull the control arms, press the bushings out (LCA big one is a beast!), compress the spring, pull the shocks and am like sh*t...might as well put some Eibachs in right? Always wanted a lower stance with my Riv and this one is no different. So as not to make this a whole project tying up my lift I got everything ordered and expedited.

Now I'm like sh*t...might as well do the ball joints too. I completely realize and understand that the arms are meant to be replaced as a complete unit...that these items are not meant to be serviceable. But I'm not that kind of guy. 😆 After searching around here and Google, and Rock auto, it's looking like Febest has both uppers and lowers. Rock auto has a GM genuine for the left lower only that's listed for special suspension FE4. Are they different from right to left? I thought both lowers would be the same, Moog has K500360 for the lower arms and is for both left and right but I don't see anything for the uppers.

Has anyone found anything other than Febest for uppers? If so what? For those that have Febest installed how are they working out?

When I installed the creative steel bushings I put these moog lower ball joints on, they show they work for CTS V and I haven't had a problem with them. Just have to be careful pressing them in, as I couldn't remove the rubber boot. I had already replaced with stock upper assembly so I didn't search for the upper ball joint. Heres a link for the Moog one I used.

I don't know if these will fit, but I used something similar for my V1 and C5.
