broken rear hub bearing?

smudge.g · 24th April 2022, 14:08

Having had my rear hub bearing fall to pieces when I tried to remove the hub from the stub axle to replace the ABS sensor, I bought a 'quality good condition' used part online and tried to fit it today. However, when trying to remove the hub after a test fit, the bearing in this one also fell to pieces (ie the outer metal rim remained on the axle exposing the steel bearings. Can I assume that simply shouldnt happen and the bearing should remain in 1 piece? I have never changed this part before these issues so not sure what should or should not happen!! Thanks for reading.

Your ‘used’ hub presumably came off another car without falling apart, so I guess it shouldn’t happen.

I have removed many rear hubs and never had one come apart

I suspect that you may have corrosion on the stub axle which is creating a tight fit ; this will need lightly cleaning off . Such corrosion could also explain why you have a problem with your abs as any rust particles can interfere with the reluctor ring to sensor signal .
I would think that you can lightly press the bearing back together , although I've never had to do that myself . Anyone ........ ?

You can, just make sure that you don't introduce any dirt into it, fitted a pair of rear bearings to mine then about a month later did the rear back plates,n/s bearing rear outer race stuck on the stub axle just popped it back in and slid the hub back on. Probably because they were Ebay specials at £27 but will stay there until it starts rumbling

This does go on and happened to me on a number of occasions. They can be re-assembled assuming the plastic ring remains in place (Usually white or beige in colour) If this is in place there is a good chance that the abs system will be largely unaffected and all will work ok. My advice is to ensure that everything is clean and the stub which it slides onto is dressed out with some fine wet n dry paper to remove any roughness, followed by a wipe over and a thin smear of grease. The bearing should not be messed with too much, if it has spat any balls out, replace with a new unit.

Thanks guys for the suggestions. i was a bit alarmed after 2 hubs had the same issue although this 2nd one looks much better condition than my original! regards.

While I understand that re-using a hub can save a few £, and one from a breaker is not uncommon. But remember to mark the hub when removing in pairs as the bearing has been wearing in one direction, if you introduce the opposite direction of rotation to a used bearing, it could last for a lesser time or fail prematurely/become very noisey quickly.
