I have no experience with zuks but lots with toyota's. I would think you need a cv to be vibe free. I will be using a cv on my build for sure. I'll be curious what the zuk pro's have to say.

I run a cv shaft. Never tried anything else with my toyota rear. Heard to many people saying it was the better way to go.

I run a non-cv rear Toy shaft to Toy rear axle vibration free. Would have to check pinion angle as it wasn't setup according to angle. I did have some vibration from spring wrap and pinion angle being off but corrected those problems and great now. Cut the eyes off an extra leaf and added under the main leaf, removed a shim from the spring pad. Yj's on shackle reverse, Toy's, on 33's. I can get the angle if you like.

You want the two flanges (t-case output and rear diff. input) to be parallel for the non-cv driveshaft...

DemoMike is right. From what I've seen the correct setup with a non CV shaft is to have the flanges parallel. Running a centered rear diff on a Zuk makes a compound angle and a CV won't work correctly. With an offset rear diff and a CV shaft, you want the pinion as straight as you can with the driveline pointing at the tcase.

CV drive shaft is the he's way to go if you are running a centered axle IMO

re: pinion angle

do a search for driiveshaft at acks faq (see link in siganature). There you will find two links to web pages that thoroughly explain driveshaft geometery.

All you have to do is match the examples which basically involves getting the faces of the flanges at either ends of the driveshaft to orient parallel to each other. Natually, if one end is a slipyoke, the smaller face of the slipyoke opening must be in a parallel plane with the flange on the differential.

The exception is CV driveshafts but even these have a correct installation description in the articles.

You will get the idea once you read these articles.

... and yes, I like CV joint driveshafts, too!

I hope that this helps!
