Do all our wheel hubs rust like this?




Is this rust normal in the outer bearing (or whatever you call it!)? I was a little surprised given I don't live in the snow, etc.

Presumably it's just surface rust and nothing to worry about?

Yes, cleaned my wheels yesterday and all 4 looked like that. My 135i was the same.

Thanks Ian, one less thing to worry about. Am getting three "road rashed" wheels fixed over the holidays, so that's enough to spend on the 1M this month!

Yup, that's what I did when I saw rusty water oozing from the seam between the center hub cap and the wheel... Brushed on some copper anti-seize and it's all good.

Also noticed that. Just included it in the 1M issues log (http://www.1addicts.com/forums/showthread.php?t=760815).

Below is a different subject re your query. Didn't check on my 1M, so this might be normal too for installation/fixing purposes.

Interesting. I know in the photo it looks like the collar nut is broken or bent, but in "real life" it looked like a normal part of the design. I'm pretty sure BMW bend the collar nut in two places when they install in the factory to prevent it from backing out. Anyone else happen to have looked lately?

Thats exactly what it's done for, to prevent the nut from backing out. If you take a look at any BMW, not just ours, this is done to the nut.

Thus proving, again, this is not a real M car.
