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

Collar nut of your 1M:

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?
