Help: Wheel bearing hub stuck on knuckle

[dirtydub01]

When I was in the same situation just months ago in my B6 S4 I backed out all the bolts about half way from the back of the bearing and put an extension on the back of the bolt and the other end of the extension on the frame. Had a buddy start the car and slowly turned the wheel, Viola a hydrailic press! Took a couple turns into the bolt then your hear it break free. A couple raps of the air hammer and it was out. Not exaclyt an Audi approved method I'm sure but its "Oh Shit I'm out of options" approved for sure.

Brilliant idea! I just ordered the other bearing, I may try the built-in hydraulic press option before the angle grinder, and report back.

angle grinder sounds a little intense.
here's my experience.

my slide hammer happened to get half the bearing out
the outer race or pulled out with the slide hammer and the rest remained.

i ultimately just removed the whole knuckle and brought it to a local shop.
they pressed the rest of the bearing out for like $20

or if you have a work bench there's a few ways to smash it out using heavy hammers and other large objects. im sure you could look up some techniques on youtube.
i don't believe my explanation would suffice.


good luck.
