Garage told me this (ARB + BAR)
Ok so i decided to take my car up to a local independant audi/vw specialist in Gildersome Leeds (M.T Motors) for a quote on the knocking noise i have had.
i said to the mechanic.
"it seems to bang when i go round sharp bends, the sound comes from the drivers side mostly - I think it could be the ARB bushes as i have heard thats a common problem"
To which he said
"ah yes i know for definet that it will be that, but you cant just change the bushes as they have changed the way they fit, you have to replace the whole bar too."
He quoted me £200 including labor to replace the ARB and Bushes.
Am i missing something ? i didnt think the bar would have to go too from reading other posts about the issue!
