Pendennis Posted February 20, 2011 Posted February 20, 2011 On my S3 I have pre 2003 front wheel bearings. I am looking to uprating to the larger bearings (after 2003). I am hoping I can retain the alloy hubs and just replace the stub axle and bearings. Has anyone done this and could confirm this is all I need to do. Looking at CC website they want to sell new hubs as a kit 😳
mic Posted February 20, 2011 Posted February 20, 2011 I think you will have to change the hubs as the outer bearing is bigger than the old type.
elie boone Posted February 20, 2011 Posted February 20, 2011 Best to buy the hub kit, you can always sell the old axle, nut and hub
Mowerman Posted February 20, 2011 Posted February 20, 2011 Recently done it myself, bought the kit from CC, and as Mic said.... The stub axles will come out with good few hammer blows....make sure theiy're not pointing towards the car!!!!! The new bearings will require a press to get them in... Kev
rj Posted February 20, 2011 Posted February 20, 2011 Ian, You certainly need both axles and hubs. /regin
Pendennis Posted February 20, 2011 Author Posted February 20, 2011 Thanks Guys, looking at the differences via the CC website, it appears the stub axle is a bit beefier on the outer area as is the outer bearing, but the inner bearing and stub axle section looks the same. Need to save up 😬
Stationary M25 Traveller Posted February 20, 2011 Posted February 20, 2011 Does look a nice upgrade. Is it worth doing ? The 2002 axle certainly looks very small in comparison. Quite expensive !
Simon.H Posted February 20, 2011 Posted February 20, 2011 Good upgrade IMO, if only to ditch those silly felt 'seals'. Old vs new picture here from when I upgraded mine after a wheel bearing ceased. http://niknak.org/g/cars/my-cars/02-caterham-7/10-02-28seized-wheel-bearing/20100303002.jpg/0/maxsize-681 I took my uprights off and put them in the vice for better access. Easier to beat the old stubs out Edited by - Shad on 20 Feb 2011 21:36:00
elie boone Posted February 22, 2011 Posted February 22, 2011 inner and outer bearing are the same on the new stub axle
Stationary M25 Traveller Posted February 22, 2011 Posted February 22, 2011 Are they sealed one side only on each bearing ... fitted with seals outwards .... with grease in the middle of the hub ... rather than 'sealed for life' bearings ?
Pendennis Posted February 22, 2011 Author Posted February 22, 2011 Either that Ian or sealed both sides as there is not a dust cap supplied with the upgrade kit
Stationary M25 Traveller Posted February 22, 2011 Posted February 22, 2011 I was looking at the photo on the CC on line parts site .... of the bearings, not the hub upgrade kit. Appears to be sealed one side only, so I am assuming the bearings are repackable ?
Pendennis Posted February 22, 2011 Author Posted February 22, 2011 Just got home and found the kit has arrived, well done CC Ian your right, one side is sealed and yes they are repackable. They (new inner & outer bearings) are very similar to the existing inner, though more roller races and still repackable. I haven't got round to putting it together yet, but I have got a question to Shad or anyone else who has done the upgrade and can remember The kit comes with a fat and thin washer, where do they go Would I be right in presuming the thin washer goes between the inner bearing and upright face and the fat washer goes between the outer bearing and the retaining nut Cheers
Simon.H Posted February 23, 2011 Posted February 23, 2011 Yup that's right on the washers. I ended up buying a couple of extra of the thin washers from CC to get my discs perfectly centred in the calipers, think I have two on each side now
