AWR-fix: Front Wheel Bearing Remove & Replace

[andrewwynn]

UPDATE: Replaced another bearing, added dimensions of the press parts so somebody could DIY out of plumbing parts etc. I also learned a new trick to push the axle out if rust is making it impossible. This was my 7 th wheel bearing replacement I have one more that I'll do this coming week.


======= Original Post =========

Just replaced my right front bearing a second time. It's the only one ever replaced and I learned why they fail from a BMW service bulletin: harsh Impact with a road hazard not age or miles.

Anyhow I took a bunch of step by step photos and annotated the process and put them in a photo album. Make sure to enable captions to see what the steps were.

I started the photos after removing the hub. I used a slide hammer to remove the hub but I used a heavy weigh to help hold the knukle to reduce impact on the three ball joints attached.

That's the album. You can post comments on individual photos if you have questions.

It took me a few hours to do the job but it always takes twice as long when documenting and it was stupendously warm the day I did this so I started exhausted.
