On the wishbone tie bar that connects the two rear wishbones with the inner fulcrum bolts, behind the head of the bolt, I can't see anything on the parts diagrams, is it a bush I can change? I've used alot of heat in the area so it's probably US at this point.

My expensive rear end shopping list is almost complete

part 5 maybe? or 10/11? A bit hard to tell from the diagram there, site got updated and it's a bit harder to read now

 

The parts catalogue does not show any bushes as separate items for the #6 Wishbone Tie. If there are rubber bushes inside it for the fulcrum bolts, they may be the same as the bushes #19 that are for the other end of the fulcrum bolt, in the #17 Pendulum.

 

After going through quite a lot of old threads, I found someone mention it is the same as the lower pendulum bush

 

I struggle with that site after the update, I just use sng's site instead, much more user friendly

 

I noticed that as well, I had it as my go-to since it followed the factory parts list setup so closely, but the recent update (past few months or so? Haven't used it in a while) is much worse to navigate. I'll check out the SNG catalog
