hi guys noticed a small knocking noise coming from the rear of my focus tdci sport and once jacked up noticed that it appears to be movement in the tie bar bush (the one that's like a blade that's bolted to the bottom of the body with two bolts) my question is is it just a case of pressing the old one out and a new one in? was thinking about removing all the subframe bits at the same time and renewing all the bushes for peace of mind and give it all a good paint, cant really justify polybushing the whole thing as im sure it will cost a fair amount.
