I'm doing a SOA on my CJ and wondering if I should go CV or point my pinion at the rear output shaft of my Tcase.

I hear CV are a bear to change?... Any info would be great.

what would your shaft angle be if not using a cv shaft?
that's your sign, not just whether it's harder to change
parts on...

To minimize driveline vibration, the pinion and transfer case yokes need to be at the same angle from parallel. If you point your pinion at the T/C, then you need to go the CV shaft to rid the vibrations. Two u-joints at the same angle cancel the vibes, and a CV type driveline has two u-joints in it that are at the same angle when the joint bends. If you don't have the pinion yoke joint straight, you will still have vibes with the CV shaft. If you have the vibes, eventually you will stress out the joints prematurally and will have failures. This might happen in other components as well.

So, you either need a non-CV shaft with the T/C and pinion yokes at the same angle, or you need a CV shaft with the pinion pointed at the T/C. Since the non CV shaft will be working at twice the angle as a CV, it will tend to wear out faster.

So, JUST GET THE CV AND KICK UP THE PINION> :flipoff2:

on a cj-5 c/v it- on a cj-7 maybe check your angles and see if your more than 10 degree's off the t-case- Jess

on my 7, i have a regular drive shaft with SOA. It does not vibrate at all

there you go- jess
