I'm having lots of problems with my 1996 TDi300 90's rear anti roll bar "knuckles" rotating the wrong way after severe wheel articulation, which requires jacking up the rear and whacking the knuckles to get then rotated back the right way round. I don't really want to permanently remove the anti roll bars and today I was told that there used to be an easily detachable rear anti roll bar available, but the maker wasn't known. Does anybody have any ideas who this might be?
