WORN vw rear HUBS, outter spun bearing. How much too much?

Hi fellas. This as been tinkering with my mind the last week. it appears the drivers side rear hub (not the carrier), i spose in other terms, the stub axle, has a slight worn contact surface with the outter bearing. Its got a slight lip, almost invisible but can feel with the finger.

Any solutions? NO WHERE near big enough for a sleeve, its tiny but there.

I just replaced a hub on the celica after the outter bearing spun on it. It was in worse state though, typically caused by loose axle nuts, cause both the vee dub and silly car had em' loose.

One oldmate mechanic suggested usually the procedure is to fill it with araldite (stub axle and internal bearing contact surface, apparently thats the usual situation (APPARENTLY), again he recommended a new one for the celica due to the 'amount' of wear.

So all in all, i spose i should put a picture. but any thoughts? suggested + - wear tolerances?

regards,
Christopher.

years ago i was showed an old school mechanics trick for this very situation
ive done it with a few tractor bearings and slasher gearboxes and its worked a treat and they cop 100x the abuse car wheel bearings do

the seat in the housing for the outter race you get a centerpop and centerpop a heap of divets all the way around but at an slight angle so it creates a small bur.
this with a dose of loctite bearing compound works everytime

never thought of doing with a car wheel bearing though as it would be a pain in the arse to get back out when the bearing needs replacing

Yes, I've seen mechanics do that on tractors many times over the years...
and they make a loctite expressly for that purpose...

usually they can be replaced using normal tools and large hammers... lol
there are a few different products that can be used to stop the tapered outer cup from spinning...
and naturally a dose of lithium based MOLY grease and it will last for ages... so long as the axle nut is tightened...
this probably also would work with Roller bearings too...
like on the rear axles of IRS beetles... NU206 etc...

cheers

PS: chris... If its going to cost a packet, there usually is another way... Lee

DONT CENTRE POP ANYTHING.
That is rough, and I will bet you wont find that method in any "mechanics" book.

Yes, there are modern chemical products that can take up wear for under bearings,
but it will be tough to get the bearing to be in the original centre line if wear is excessive.

That centre pop method is fine if it is for a tractor and no parts are available,
but if your stub axle bearing surface is worn, find one that is not worn!!

Buy some measuring equpment so that the one you get, is not worse than the one you have now.

If you had to put a tolerance on the diameter, I would say that about 0.05mm would be a fair wear limit.
(Compared with the unworn section).
