ECR Posted January 24, 2013 Share Posted January 24, 2013 I've just cracked the flange on one of my front hubs whilst changing a wheel stud (it fell on the floor !). Caterham can no longer get the Vauxhall race hubs which were steel (well certainly not alloy) so I'm obliged to fit the uprated hubs on both sides. Are there any gotcha's to this ? Do I remember a bad batch of bearings circulating (or was that rear hubs ?) . Off to Portugal in March and I'd hate to have a hub problem. And Does anyone have a spare VX race hub ?

Stationary M25 Traveller Posted January 24, 2013 Share Posted January 24, 2013 A good upgrade. Same size bearings inner and outer. Chunkier stub shaft. Better bearing seals ..... no more felt !! Link to comment Share on other sites More sharing options...
Paul Deslandes Posted January 24, 2013 Share Posted January 24, 2013 you might consider it too risky but have you considered getting it specialist welded? (its only 25% of th studs after all 😬) Did you sort the clutch? Link to comment Share on other sites More sharing options...
ECR Posted January 24, 2013 Author Share Posted January 24, 2013 Too many pieces to weld ... (and I wouldn't fancy it anyway) Link to comment Share on other sites More sharing options...
Englishmaninwales Posted January 24, 2013 Share Posted January 24, 2013 Quoting ECR: Do I remember a bad batch of bearings circulating (or was that rear hubs ?) There was a faulty batch of rear hub bearings about 4-5 years ago. Malcolm Link to comment Share on other sites More sharing options...
elie boone Posted January 24, 2013 Share Posted January 24, 2013 ECR, i have 2 compete uprights ( upright ,stub axle hub,trunnion ) from my Ginetta that i don't need and could sell it's the Spitfire PCD and at least 1 stud is not a tight fit so you have to renew the studs.

CageyH Posted January 25, 2013 Share Posted January 25, 2013 As long as you have access to a hydraulic press, the job is pretty easy. The hardest part is getting the old stub axle out. Link to comment Share on other sites More sharing options...
Harry Flatters Posted January 25, 2013 Share Posted January 25, 2013 Roger, as CageyH says, you definitely need a press to remove the stub axles and when they go, they go with a big bang Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted January 25, 2013 Share Posted January 25, 2013 Presumably a different design to my 2002 build ? I slackened the nut that holds the stub shaft into the upright a few turns and hit it with a big hammer to break the taper. Job done. Link to comment Share on other sites More sharing options...
ECR Posted January 25, 2013 Author Share Posted January 25, 2013 Yes, I have a press ... Are the hubs still cast alloy like the previous version ? I had fatigue cracking problems with those which is why I went to the steel race hubs. Elie It's the steel hubs that I wanted .. (although now I know the new ones are billet made I've decided to go with them) Edited by - ECR on 25 Jan 2013 08:05:09 Edited by - ECR on 25 Jan 2013 10:16:47 Link to comment Share on other sites More sharing options...
Harry Flatters Posted January 25, 2013 Share Posted January 25, 2013 Roger, the uprated hubs are CNC machined from billet ali Edited by - Harry Flatters on 25 Jan 2013 08:20:47 Link to comment Share on other sites More sharing options...
Harry Flatters Posted January 25, 2013 Share Posted January 25, 2013 Ian, I too have seen the stubs come out with a whack, but usually they need a press. Link to comment Share on other sites More sharing options...

ECR Posted January 25, 2013 Author Share Posted January 25, 2013 Thanks Harry I'm content to use them now they're billet made. My existing steel hubs are 16/17 years old so well overdue for replacement considering the use they've had. I'm happier to part with the £250.00 now .... Last time I removed the stub axles a press was certainly needed ! As you say, when they go they go with quite a bang. Link to comment Share on other sites More sharing options...
ECR Posted January 29, 2013 Author Share Posted January 29, 2013 Right, the upgrade kit has arrived. Not got it to the car yet, I'm just unpacking the box. All looks straightforward except for the 2 collars/shims. On the invoice one is described as " outer collar - 2003.-front hub-between nut and bearing" I guess that is the thick one and it fits outboard, and the large nut tightens against it. Where does the other (thin) shim go ( against the upright ?) Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted January 29, 2013 Share Posted January 29, 2013 From distant memory again ... One goes on the shaft, between the bearings. It will be the same thickness as the shoulder inside the hub. Edit ... the acid test (of my memory) will be ........ getting the disc in the middle of the gap in the caliper Edited by - Stationary M25 Traveller on 29 Jan 2013 18:03:26 Link to comment Share on other sites More sharing options...
ECR Posted January 29, 2013 Author Share Posted January 29, 2013 Hmmm But the bearings are both taper roller and presumably both the outer races are pressed in to registers. Wouldn't a spacer between the bearings defeat the object .... ? Edited by - ECR on 29 Jan 2013 18:40:42 Link to comment Share on other sites More sharing options...

Paul Deslandes Posted January 29, 2013 Share Posted January 29, 2013 Not sure if this is the kit that you bought and I would have thought that it should have included instructions etc. In case not and its of some help, here is a rather poor copy of them as issued by CC some time ago.

Stationary M25 Traveller Posted January 29, 2013 Share Posted January 29, 2013 Cheers chaps .... my memory was clouded by years of working with a hosereel clutch with two plain bearings and a spacer in between. Link to comment Share on other sites More sharing options...
ECR Posted January 29, 2013 Author Share Posted January 29, 2013 Thanks guys Shopping tomorrow ☹️ so fitting will have to wait ... I'd have thought that the kit (which is what I purchased) would have included some instructions as well ...
