Hi AW, these bushings are in the rear axle Lower Control Arm and they are supposedly Lemforder. These are at the inboard end of the rear LCA (FCP calls the LCA "swing arm")
Originally I had camber set at 1 deg. Over the past year I slowly saw the LR camber increase and I think one of the bushings simply collapsed, I will see once I pull the LCA out of the car. The RR didn't seem too bad. The LCA is #15 in this image.
I guess I will have to accept that these are high frequency maintenance items for now..... I have my own 20t press so at least it should be a one day job to pop them out, replace the bushings and put them back in.
Just feeling dumbfounded that this happened in such a short interval.
