Trew has it spot on i
I'd then say HD springs, at least on the back but probably all-round, new shocks, but it might also be worth replacing all the rear end bushes ... ARB's, A-Frame and have a good look at the wheel bearings at the same time.![]()
It could be just the dampers (aka shocks) that need replacing. Check the rear body mounts as well and the bushes on the link assembly on the rear axles...... the problem i have is the disco when driving feels at the back like its moving a bit from side to side and some one said its my springs so i thought i would replace them.....
Terra Firma are the best that you can get. Avoid Britpart.
