When changing my rear anti-roll bar droplink and adding a polybush, I noticed the apparent poor state of the rubber around the lower rear subframe mount (the round one with the bolt in the middle).
Can anyone offer any advice as to the condition of this one? The other side looks similar as well.
Is it possible to change them without removal of the subframe? Can it just be unbolted, the old one removed, and a new one fitted?
Or should I just leave it alone?
