Hi Fella's,

I've got a Double, Double Cardin 1330 Drive Shaft in my TJ:



Sorry for the monster pic.

My reasons are running this shaft was because I wanted to see if it would fix the small amount of vibrations that I was getting from my 8.8 being offset 3" to the passengers side. Also, I got for free from someone who owed me a favour and its a tad stronger than my old 1310 XJ Front Shaft cut to fit out back.

Anyway, when I originally installed it I kept the same Pinion Angle as I did with my previous Double Cardin shaft. The result was some very serious vibes.

I dropped the pinion angle down to almost the same as it would be with a normal standard 2 joint driveshaft. Seems to be much better. So because this shaft has 2 CV Joints should the angles be set the same as a regular shaft?

Thanks

Scotty

Thanks for confirming that for me....

I looked at all the Custom Driveshaft sites but none had any info on angles for this type of shaft.

Double carden joints are self cancelling, effectively acting as one complete driveline, which is why they're referred to as a CV. This allows a double CV drive line to run at independant angles. However, excessive angle on a CV joint with still cause some vibration (not a true CV joint, in other words). If you experience more vibration when zeroing the angle on one end, I would suspect excessing angle or balance problems.
