I have an '01 325i with 210,000 miles on it. I am placing an order to replace all four wheel bearings, rotors, pads and rubber lines with braided steel lines. I'm curious if, with the high mileage on it, I should replace the rear axles while I'm in there. They need to come out in order to replace the bearings so figured this would be a good time to do it. What are your thoughts? Thanks in advance.
