Depending on the year Audi fitted non replaceable bushes, meaning the whole anti roll bar needs to be replaced. Saying all that it hasn't stopped us at the garage opening the brackets changing the bushes and spot welding them back up. Never had an problems and that's over 20 A3s. But if you wish to change the whole bar from what I can recall its £95 from TPS.
i might just open the bracket and then bolt it back down . the bracket looks like it is in two half's but just cant separate them , so in my case i don't think i will have to weld them up.
how do you mean weld them up.what do the ones that are permanently on the bar look like ? do they look like its in two halfs ?
