Cardan Propshaft (Scorpion?) UJ replacement
JDB:
Evening - a little bit of help please.
I have a (I think) Scorpion Cardan Propshaft, the UJs were a little worn, I have replaced the front one (part no STC 3466 I recall).
I need to replace the rear one (STC 3466 again I think) and the one with the whole through for the ball joint - does anyone know the part number and the method of extraction/replacement?
Prop is on a Disco 300tdi if it makes any difference.
Pics as below

I'm not getting you mate, probably me being dense but...
3 ujs, 2 at the front one at the back, lets call them back middle and front starting from the Tbox.
I haven't got one but from those pics they just look likle standard UJ's, circlips off, few whacks with the appropriate socket in both directions, pop them out, fit new ones. You've done two already, is the 3rd different?
It looks almost as if its just 2 uj's butted up to a spacer/mating plate. Is that where the ball joint you mention is, through the middle of there?
If it is I can't see any bolts or owt so I'd strip both middle and front UJ's, remove the yokes and see whats what when you've just got the centre part of the double joint in your hand.
Stu.
JDB:
..... the middle UJ has a hole through it for a shaft - at the end of which is a ball and socket joint which is part of the join to the third UJ mount - see the 2nd photo - you can just see the side of the ball. Normal "whacking"does not work! Its not as simple as 2 UJs welded together!
Range Rover Blues:
I can't seeform the photo if they are held in by circlips but you are right, a normal UJ overhaul kit is useless for the Cardan joint.
Have you tried contacting Scorpion direct?
If they are no help trawl the yellow pages for a propshaft specialist, I'd recomend Propshaft Technology in Rotherham but you aren't local.

Hi
It looks a bit like the early series v8 shafts.
They had nylon injected around the "circlip "groove, which is machined into the UJ and not out side as you would expect.
If you have no joy with scrapiron try these guys www.propshaft.co.uk/
They rebuilt one of my carden shafts.
regards
wizard :twisted:
