To fit 2000 model S3 I need the part number for a rear bush, which a mechanic has called a rose joint bush! GSF have no idea what i am talking about, and said they do not list anything like i am describing. Audi main dealer said take a picture and bring it in to help them identify the part i want. The bush in question, is the lower rear bush that the track arm bolts onto. The middle of bush can turn, as if on a ball joint, to look at it looks like a normal bush. It can be bought as part of a kit on ebay for £130, but i only need one bush: Audi S3 98 > 02 Quattro Rear Suspension Arm Repair Kit on eBay (end time 07-Mar-11 12:05:12 GMT) Know what bush i mean? Is rose joint bush the correct name? Do you know the part number? Anyone know where i can get one from? Other than main dealer.
