Hi all... I'm a new Buick owner (91 LeSabre) (well, the car is not new, but is new to me.. ) and I have a quick couple of questions for the gurus out there. First, can anyone give me some basic info about replacing wheel bearings? How tough? I'm no mechanical genius, but between my father and I should be able to tackle this. The shop wants $225 for the job and surely I can do this much, much, much cheaper. I did a search but didn't find much reference to this. The car is vibrating, especially at highway speeds and more so when turning the wheel to the left and we're really suspecting the bearing. Second question... the power windows in the back do not work. I found another website that made it sound like that was a common problem with these cars. How tough to replace those and how expensive if a shop does it for you? Thank you in advance, really would appreciate the help!:TU: Rachelle
