Removing bearing from drive flange?
Slater - 26/8/06 at 08:56 PM

How do you remove this bearing from the drive flange? see pic below.

Do I need a puller or is there a locost method?

I just want to remove it to give it a good clean and put it back, as I put the complete upright/hub into the electrolysis bath and ended up with rust debris in the bearing.

you will either need a puller, or you will prob destroy it trying any other way, i would not even bother trying to take it apart and clean it, they are not designed with that in mind, and surely a new bearing wont set you back too much?

They can be difficult to remove without damaging them, depending on how tight they are. Probably not worth the risk, just give it a good clean with petrol etc. then blast it with airline, repack with grease and reassemble.

Shouldn't actually be horribly tight. A good clean bearing will just slide onto a good clean hub. You might get it moving by tapping a screwdriver between the inner race and the hub. If not then i wouldn't bother. A good dip in a tub of degreaser deep enough to submerge the bearing and a fiddle with a toothbrush should do the job.

Looking at the state of the rollers in your picture, they seem to be well past there best. Just lever it of and fit new, at least then you know its going to be OK. Other way you take it of, clean and re-fit, re-pack with grease, and then find out its nackered, and "say wish I had replaced it". . Regards Ray

They do seem to vary tremendously, I've had bearings that I could literaly lever of with a prybar, but then again I broke a hydraulic puller getting a bearing of my MR2's front upright! Eventualy got the angle grinder onto it and weakened the race enough that a few taps of a chisel cracked it.

Just had another go with degreaser, chisel/screwdrivers and prying the thing off. No luck, I'll try and either borrow or buy a puller. It needs to come off as the oil seal had disintgrated so I need to get the bearing off to put a new seal on. May as well just get a complete new bearing set. more ££££££ but at least I'll know it's got a new bearing.
Thanks anyway.

If you remove the cage an rollers (be brutal) a bead of weld on the bearing face from a mig welder should expand it enough to make it drop off.

Replacing the bearing is definitely the best course. The amount of work to do the job later would be frustrating, to say the least. Besides, safety counts! With that in mind, I'd just cut most of the way through the race with an angle grinder...a couple of smart raps with a hammer, and it should fall right off. No point in messing with a puller if you're going to replace the bearing anyway!
