I've just had the front right lower arm and bush changed to get rid of the horrible nocking and wooly steering. My advise to anyone wanting to do this on their driveway with axel stands is to not bother or allow 2 days where it isn't raining or windy. I had a local mechanic do it for me for Ã‚Â£70 which isn't too bad given the arm chewing nature of the job, but he said I'd have to keep an eye on the clutch as it's on it's way out because the pedal is heavy.
I havent noticed any difference in the clutch though
The main reason I bought the car was it had a new clutch fitted... but the bloke I bought it off transported timber in the car without using a dust sheet and managed to get white paint on the carpet...
