Greetings! New poster here from Tulsa, OK with a question about rtab... I have a '98 328iC with the original rear trailing arms (107k miles). Due to terrible tire wear I went to my tire shop to find the trouble and was informed that my rear trailing arm bushings are very worn. They said it was not possible to replace just the bushings as it only comes complete (and quoted me $1700.00!!!). Another shop said if they are the original rta then they have to be replaced but with aftermarket rta the bushings only can be replaced. I don't know who to believe at this point! So, can the bushings only be replaced on my original rta? If so what should I expect to pay for parts and labor? Is there a "better" aftermarket bushing that anybody can recommend? If the entire rta needs to be replaced, what's a fair price for that? Thanks!
