grab a few second hand 80/100/GU cv's and experiment? heat control will be the key, the only real drama you might have is finding a boot to suit that doesn't expand and/or shred at highway rpm.
could probably even use smaller/cheaper CV's, tailshaft torque will only be 1/3 - 1/4 axle torque.

The boot on a tailshaft CV will be doing far less RPM than a FWD CV boot. Didn't the company that makes the drilled greasable CV make a CV boot for late 70 series CV's?dumbdunce wrote:grab a few second hand 80/100/GU cv's and experiment? heat control will be the key, the only real drama you might have is finding a boot to suit that doesn't expand and/or shred at highway rpm.

Mal's bushrangie runs 100 series CV's in the shafts. I was told by the guy that made them that he drilled out the flange so that the CV would be a press fit, pressed in the CV, welded it up, left it to cool naturally and they're still going.
Two other options, www.yuri4x4.com or Dobbin Engineering

bzzt a tailshaft CV in a 4WD will spin at least twice as fast and more like 3 - 4 times faster than a front wheel drive CV.sierrajim wrote:The boot on a tailshaft CV will be doing far less RPM than a FWD CV boot.

I like the booty 100 series option. got me thinking about doing the front on my 80Mal's bushrangie runs 100 series CV's in the shafts.

Dobbin makes them and we run them on Glen's, Pete's and Phill Nobles Trucks all with 44" plus tyres ,strong but not much good for hyway driving if you run them to much angle as heat is a problem.Boots are easy to get but speak to Glen he can make you a shaft any length for about $800 complete bolt in

Cooter , I have tried to run a rear cv about ten times in my zuk , I used a 1.3 suzuki cv and parted of the stub axle , then left just enough to weld a standard zuk flange on , one I cut off a standard tailshaft , then welded it to the bell. The main problem is heat as they spin up to five times the speed they where meant to , so they will get hot spots where the ball bearings contact the bell of the cv. This will cause it to be notchy and become loose. Also the boots will shred as the grease melts it runs out and the centrifigal force breaks the boot and the extra heat doesn't help. I managed to find some boots via Garth and Glen which did the job but I could only grease the bell only which isn't much grease. This stopped the boots breaking but Istill had the overheating problem. I ended up angling my transfer case sideways in the car and down at the rear. This fixed my tailshaft angle problem and I know run uni's. I still have my front cv as when angled down at the rear the front uni could not cope with the angle so it is a cv and has no problem. All the guys run cv's in there comp cars but there comp cars don't do 110 down the freeway for hours on end. The commodores might run a cv in there shaft but the angle wouldn't be much and the final drive ratio would be nothing like a 4wd , but if you wanted to you can run any cv you want as stated there is not as much pressure on the tailshaft compared to axles , Just m2c , Cheers Paul.

fill them with oil not grease, that way they won't get as hot. keeping it in there may be a problem though.
Also cv's are exactly that constant velosity, so ideally you have no angle on the uni as the steeper the angle gets the more the speed changes during rotation.
also depending on the application i would be careful with failure. Nothing is more annoying than something like this letting go.
What about patrol double cardian tailshafts from the front of leaf sprung utes. I bought one for $100
