Hamish Posted October 26, 2019 Report Share Posted October 26, 2019 Where is the best source for uprated, beefy, strong front stub axles for TR3a and the associated hub bearings. I don’t know the age of mine and they have had a few years of abuse just in my limited ownership. Your thoughts welcome on sources. H Quote Link to post Share on other sites
stuart Posted October 26, 2019 Report Share Posted October 26, 2019 I have used the Moss ones with parallel bearings with the ally hub kit Stuart. Quote Link to post Share on other sites

Yes thats the one though I see they have changed the bearings from the last time I fitted them, they were sealed bearings. Stuart. Quote Link to post Share on other sites
Waldi Posted October 26, 2019 Report Share Posted October 26, 2019 If they were sealed bearings, they were probably not the taper bearings shown now, which are adjustable. Waldi Quote Link to post Share on other sites
Hamish Posted October 26, 2019 Author Report Share Posted October 26, 2019 Can you use either bearings in the same hub ? is there a quality / strength difference ? Quote Link to post Share on other sites
stuart Posted October 26, 2019 Report Share Posted October 26, 2019 IIRC They changed hub suppliers and the new hubs have these taper bearings whereas the old ones didnt. Stuart. Quote Link to post Share on other sites

Chilliman Posted October 26, 2019 Report Share Posted October 26, 2019 Got this same kit sat on the shelf waiting to be fitted - I've just checked and it now comes with Timken tapered roller bearings as Stuart refers to... Quote Link to post Share on other sites
Waldi Posted October 26, 2019 Report Share Posted October 26, 2019 2 hours ago, Hamish said: Can you use either bearings in the same hub ? is there a quality / strength difference ? Hi Hamish, If the previous sealed bearings were single race ball bearings and the current bearings are tapered roller bearings, that is an improvement. Firstly because they are adjustable, secondly because of the (very likely) higher load capacity. I say “very likely” because I do not know the actual bearing numbers, but the taper bearings have a line contact, which normally results in higher load capacity compared to ball bearings of similar size.

Hamish Posted October 26, 2019 Author Report Share Posted October 26, 2019 Thanks Waldi that’s nice to know. Are there uprated stub axles without the light weight hubs as a kit ? or do you need the new hubs with uprated stubs ? Quote Link to post Share on other sites
harrytr5 Posted October 27, 2019 Report Share Posted October 27, 2019 Classic Car Developments supply the same type of kit. They will also fit longer studs if needs be. Good company. Regards HarryTR5 Nutter Quote Link to post Share on other sites

harrytr5 Posted October 27, 2019 Report Share Posted October 27, 2019 I thought they came from the same supplier Stuart, but just goes to show how wrong I was. Thanks for the heads up though. Regards Harry TR5 Nutter Quote Link to post Share on other sites
roy53 Posted October 28, 2019 Report Share Posted October 28, 2019 Hamish you might find help by talking to Nigel Reuben the TVR builder who developed the uprated parallel bearing stub axles. ROY Quote Link to post Share on other sites

Waldi These are the tapered & sealed wheel bearings that were provided in my kit. Both inner and outer wheel bearings are the same, Vastly improved with an nice reduction in unsprung wheel weight.

Andy303 Posted October 29, 2019 Report Share Posted October 29, 2019 I have read on another forum that fitting just the spacer, ala MGB, is sufficient to strengthen the stock stub axle for street use and provide the desired bearing separation. TRF sells the spacers, HP660, stateside: http://trf.zeni.net/TR4-GB/89.php Quote Link to post Share on other sites

TRF sells the spacers, HP660, stateside: http://trf.zeni.net/TR4-GB/89.php Their spacer seems to go with the uprated stub axle not a stand alone part. Revingtons do a spacer kit to fit the standard stub, this just deals with so called pad knock off. Its a bit of a faff to fit as you have to shim it up correctly which takes a few goes to sort out, personally if your worried about the strength of the stubs then do the whole thing with the straight shafts and hubs. The TRF kit is expensive for what it is. Stuart. Quote Link to post Share on other sites
Waldi Posted October 29, 2019 Report Share Posted October 29, 2019 I simply replaced both stub axles by new std ones. They should give me another 50 years of roads ahead, by which time I will have entered the top 100 of oldest people, in my town at least:) Waldi Quote Link to post Share on other sites
Hamish Posted October 29, 2019 Author Report Share Posted October 29, 2019 Thought I’d share with you why I’m looking into upgrading. 185 sticky tyres will create some added stress when doing this. But interestingly I don’t suffer pad knock back in the current arrangement. And the spins finished the season 2nd in class and 7th overall. Quote Link to post Share on other sites
