A couple of years ago, I fitted cheap front lower rear control arms. I really wish I hadn't. Anyway, I had a set of Lemforder front lowers and bought a set of meyle rear control arms. I was under the impression you had to take off the cv joint. As it happens, you don't. Which is nice. Got one side done this afternoon after doing a cv joint on the A6 and being called out to a kitchen fire. So I'll get the other side done tomorrow. already feeling better!
