Wheel bearing removal
« on: November 10, 2012, 06:57:50 AM »
I've tried a drift, heat and penetrating oil but still can't drive these bearings out. I did remove the retainer and I'm trying to drive each side "out" by catching the tiny lip of the bearing with a drift.  Any tips I haven't tried? Could I even get a puller between the inner spacer and the bearing?

You'll need to use a bit of force to push the spacer over to the side a bit so you can get a bite on the inner race and drive them out. I usually use a big screw driver.
Or use a blind bearing puller.
Either way you have to force the spacer out of the way.

Just use your hand to cock the screwdriver to the side or do I need to apply more than hand pressure?

Depends on how strong you are and how big a screwdriver you use.  ;)
You may have to give it a whack.
You'll bend the tabs on the spacer but that's ok, you can bend them back before you reinstall.

I had the same problem till I read the posts on here. That retainer need to be bent down so you can get good contact with the side of the bearing. Mildly heating the hub around the bearing can make the aluminum expand a bit before the steel does. Get a good piece of the bearing edge exposed and give it some good whacks in a circular pattern and it will come out. Take your new bearings and shove them in the freezer now so they freeze down good. They will almost drop in place. Tap them down with the old bearing.

I'm not saying it's time to try this but this is something I've done when I can't get a good catch with a drift punch. Use a Dremel with a cut off wheel small enough to fit inside the bearing's inner race. Grind a notch that the drift punch can catch onto. I've done this as a last resort when nothing else works.

Can I have a motorcycle when I get old enough?
If you take care of it.
What do you have to do?
Lot’s of things. You’ve been watching me.
Will you show me all of them?
Sure.
Is it hard?
Not if you have the right attitudes. It’s having the right attitudes that’s hard.

once you get the spacer shifted, hit the isht out your drift on one side of the bearing, and the repeat on the opposite side. repeat. itll come out.

On a side note, had problems shifting the spacer on the rear. Went to autozone, they loaned me a blind hole bearing puller. Super easy with that.
