A little Help With Drive Shafts
Discussion
I have an odd problem. I have finally managed to get my diff. installed and so turned to the drive shafts. They are all cleaned up and painted and ready to go in, but when I tried to fit new UJs I found one drive shaft took standard GUJ102s as per Triumph TR6 and the other was slightly larger. The new UJs didn't fit. The flange ears are wider apart too, althoug they fit at the diff and upright ends.
The drive shafts look slightly different too:
I wondered whether I might have one Triumph 2000 shaft and one TR6 shaft, but I dont think so. Both are designed to take GUJ102s
Any ideas what is happening here?

]Thanks for the reply Adrian,
I have checked the flanges on the diff and uprights and all four are identical as far as the connecting face is concerned. All the drive shaft flanges match the female flanges on the diff and upright. It's just that the distance between the ears is slightly larger on the second shaft. If I measure the distance between the circlip channels, on the two, one is 84mm and the other is 89mm (best I can do with my eyesight!)
Puzzled.....Do Tuscans run an updated drive shaft? The rogue one does look like it is generally beefier. Thicker coller and thicker arms to carry the bearing cups

The Jag diff cars run with the larger UJ, but then your larger unit looks after-market, that said, I thought that the register on the upright end was different from the diff end.
Adrian@
I can only vouch for my car, the registers are identical. I can swap the driveshaft flanges from upright to diff and they fit fineAdrian@
Perhaps I should fit Tuscan UJs

My Vixen with upgraded TR6 diff has odd drive shafts - I got them from DG, and didn't realise until I got home. One looks 'classic' Triumph, the other looks like an aftermarket one, and uses larger UJS and a different flange design. (It looks quite different to the photos )The splines are the same though, which implies you would be able to get a single 'odd' UJ which is a different size...
(It all fits together perfectly, so perhaps TVR did do some aftermarket ones ?)

Left hand shaft in photo is off a Winget dumper truck, right hand one is Triumph 2000 based
Thanks Steve. The dumper tuck connection has been mentioned on here before; are these the correct shafts or have they been mixed up? Can you tell me which UJ to use?Edited by Astacus on Monday 28th May 07:02

Instead of pissing about pushing spiders and yokes into holes you could always just get 2 brand new driveshafts made up at about £120ea which will fit, be new, not have any ovality in the yokes and match end / end and weight to weight...
Just a thought??
N.
Yup, thought. In fact the triumph one is new, and I replaced one dud yoke, which was oval. Original was identical but rusted utterly solid. The new yoke was, let's say, of disappointing quality.Just a thought??
N.
The other one was fine (shockingly) and the yokes had nothing wrong with them. I know what you mean about having identical drive shafts, but ............
I don't know... There really should be no balance issue side to side. It rotational balance I would be concerned about on a road car. Shaft yoke and spiders works out at about £180 quid
And I was going to spend the money on new wires
Meh

Well, I never realised there were so many types of UJ!
I found a website with a GKN catalogue and did a bit of measuring with a micrometer and it does indeed look like my second shaft has 1310 type UJs. I am going to order a couple, try and get them by Saturday and see if they fit. cheers again Ian.
Dewi, thanks for the offer. If I can't get them to fit I will mail you.
