I just replaced mine on a 1995 Bmw ic. I had to redo a bodyshops work. Someone hit me. So part of the repair was they replaced my wheel bearing and lower control arm. Well they didn't seat the bearing correctly and when I happened to lift my car on my hoist I notice play in bearing. I took my wheel off and notice they hit my bearing hub to install the bearing and they expanded the nub that centers the wheel to the hub. Because it was expanded the wheel was force on the hub and it gouged my wheel were it mounts to the axle hub. I had to replace the bearing and the hub.
I am currently still trying to get them to return my money for what I repaired.
I guess my point is that you should take to a legitimate shop that does these type repairs.
I think they didnt have the proper tools to do such a repair. Also when replacing your bearing you should align car afterwards. I marked my control arm location so I could reinstall to the exact location so I didn't realign the car.
I think if you have never done this repair before and don't have some that has done this repair with you I do suggest that you take to someone else. The bearing when installed needs to be preload and you need to have a feel for this.
Hope this helps.
This is a pretty major job, i just had mine done on the left rear side and you have to take evertyhing off clear down to the axle, a friend of mine is a mechanic and took about 5 or 6 hours for one side. yeah you can get the bearing pretty reasonably at bimmerparts.com, i bet the dealer would charge 3 or 4 hundred dollars a side. dide mine for about 100 a side
it's not really hard at all. it's just labor intensive. get the bearing (+\- $40.00 ). spend 15 bucks more on the mechanics manual (discount, pep-boys) and read up on it. if you need more explaining e-mail me and i will more than happy to tell you how. hek, i am not a mechanic and i have already done this twice in the life of my car and only the frst time took about 5-6 hours to complete. you will also need a hub since the outer bearing race will be stuck to it and more than likely you will damage it, but if you can save it you'll save about 75.00 bucks
