[QUOTE=Jetboy;3765892]FWIW - It's very likely the result of the bushings. Poly bushings are not an upgrade in many cases and are not appropriate for the rear control arms. The rear control arms require more complex motion than a simple hinge joint like the front suspension. The ends need to both hinge around the center bolt but also twist axially as the link rotates and flex out of alignment as them move through the various suspension motions.
Jetboy, as always thank you for your thorough reply! That makes sense and I'm not arguing at all. But.... if the bushings are the issue and these bushing seem to be a relatively common "upgrade" to the rear suspension. Why is this the only instance I've seen of the upper rear control arms failing?
My bad luck? (That actually makes sense, I am a walking perfect storm) I've run them longer than others? Maybe. (I looked it up I installed them almost exactly 3 years ago, November 2019. about 40,000 miles) It seems really odd to me
