My car (1.8vvc) is now 17 years old, and done 30 000 miles. All the suspension is original, except the four shocks which I replaced with upgraded Nitrons last year. I have been getting an occasional knock from the rear A frame bush, so have removed the A frame from the car. Both 'race washers' were in a very poor condition, and I suspect that has allowed the frame to touch/knock on the de dion tube. To the eye all the bushes in the A frame seem in good condition. I have replaced the De dion bush 'just in case' which was a pig to remove and inspecting the removed bush it was in good condition. How long do bushes last on a road car - are the trailing arm bushes easy to replace?
