rear wheel bearings

I'm refurbishing the rear brakes etc in preparation for re - installing onto my replacement subframe. One of the stub axles has a bearing seized/worn as it feels lumpy when turned (i haven't taken it apart yet) , got the hubs dismantled, disks off, just the dust shields / camber adjusters / hubs and abs sensors left attached.

Excuse my laziness but do these have an inner and an outer bearing? And Can the hub nut be re-used as I don't think these have the good old fashioned split pins!

Any tips appreciated.

Just buy a new bearing and do the job right!

The only problem you may have is that when you remove the old bearing the race may be welded to the stub axle, get your self an angle grinder and carefully thin the race and then split it with a hammer and flat blade screwdriver or chisel. A new bearing will come with a new hub nut and race, the only thing you will probably have to do is add more grease to the new bearing as they are not generous in their application.

Its a relatively easy job! and if you are going to do it do it right, so buy a new bearing.

ER.

Clicking on this link just took me to a windows security message telling me that I had just downloaded viruses and trojans etc!

I think I'll get a new bearing.

I've done a few - many years ago, didnt realise the "bearings" comprised of the whole unit the disk/wheel/abs wheel is mounted on, I thought I'd just be relacing a couple of bearing races front and back that fit inside! Arent these available seperately??

Perhaps just coincidence - but its the fist time its happened on this computer!

Its one of those programs trying to sell you their anti-virus software, I just ignored it, the system I'm running has a very good anti-virus package and firewall, so I'm not concerned,

Thanks for the link I managed to get to it eventually. I've done that kind of thing before but always replaced with new bearing sets. I wont know what the issue is with mine of course until I get it to pieces.

Its easy and not particularly expensive (about £60 - buypartsby or shop4parts). You just need to know if you have the earlier optical (toothed) or later magnetic abs sensor - change happened about 2000. My inner race was stuck on the stub axle but got it off by heating it. Others also advise packing extra grease in the new bearing as they can be a bit lacking.

Does anyone know the size of the hub nut? Its way bigger than anything in my socket set, so will need to order the right one.

Also from these pictures do I have the optical toothed abs sensor (looks like teeth on the inner hub)?

cheers

Make sure you tighten the new hub nut to the correct torque.

(page 382 of Alfa Romeo GTV 916 Repair Instructions Vol 1)

Will I need a breaker bar to get this much torque?

Something like that!

A torque wrench going that far up the scale will probably cost you £100 if you dont have one (like me).
