locost rotoflex/cv conversion

Yeah, but one Volvo does two Triumphs.  The Metros are taking a bashing though, I robbed 5 last weekend and that's just 2.5 Triumphs worth  ;D

I quite like the Escort inner joint idea.  Might be a space issue though as the Tripod 'pot' is quite long and there really isn't much room..... :-/  Measure carefully before expending money/effort modding the joint!

May be worth considering Nissan shafts if thinking of going down this path.
Are readily available second hand and cheap.
Look stronger than Triumph ones from what I saw when fitting a pair to a sedan.
CVs are more ideal for transmitting rotary movement but more ideal than actually required for this purpose and are much heavier.  Universals are quite adequate for the range of angular movement used in a non-steering driveshaft.
Relying on a rubber boot to prevent a very expensive repair worries me having stripped a few VW Transporters in the process of building a camper.

The Datsun shafts are a larger diameter as they have ball bearings between the two shafts to provide the plunge. Not saying it can't be done but they are a larger diameter.

The Datsun conversion works wonderfully on the big cars, although I have heard rave reviews regarding a CV conversion for 2000 / 2.5 / Stag / TR (IRS); not cheap though.

I think the CV is the way to go for Rotoflex, as Slimboyfat says 'they were designed for it'.

To resurrect this thread. I have completed my conversion and driven it, what a difference.  :)

TBH 3 changes have been made to the rear suspension in one go.

  • Escort / Volvo CV conversion using OE bearings.
  • 1/2" Lowering Block
  • Alloy Wishbones

No wind-up to the drive-line (2.5PI & 185/60-14"), less vicous when driving over bumps - less unsprung weight curtesey of the wishbones, doesn't feel quite so twitchy with the lowering block.

and the brakes feel more solid  :-/
