I'm doing the lower rear bushes on Dean's car next week. The lower arm has one single-piece bush which is £40+ from Audi or £12 from Meyle. It also has a split bush which is £22 per half, as does the hub so £180 for all 8! The upper arm has three bushes but I've not priced those as they are fine on Dean's. Guess about £20-30 each.
The rear tie rod is only available as an assembly - no separate bushes. Those are also available from Meyle. Factor in a new eccentric bolt and washer for that as they rarely come apart nicely. There's a little link arm which doesn't get much action so doesn't wear much, and also link for the ARB. I think to do all the suspension bushes its a £600-800 shopping list. Double that to do the subframe mounts and diff mounts as well.
You'll need a press or a very large vice and corresponding drifts to change all the bushes. No doubt I will be making some tools to assist with the task when I get round to it
