I pointed the pinion of my 14 bolt @ the X-fer case and I expected to have some driveline vibrations and I have a C-V joint I can put in.

So far from 0-50mph there is no vibration. I have yet to take it to highway speed since it's not registered or insured.

Does this mean I DON'T need a C-V joint. Or should I still use one to extend the life of my joints??

Thanks in advance :)

Your going to destroy your rear joint.

Your suppose to have equal angle on the joints when running a 2 joint shaft.. that way the u joints are actually working.

Your suppose to point the pinion 2-3 degrees down from the output of the tcase if you are running a cv rear driveline, enough angle on the rear joint to make sure its constantly working.. If there is no angle on the rear.. you will end up burning the joint up

just my .02

Mine has been pointed straight at the rear of the case for years without a CV and I have never lost a joint. I think that is a bullshit theory about it wearing out joints.

Well, what you're supposed to do and what works are two different things. My pinions pointed directly in line with the shaft. I'm constantly greasing the 1410 to try and avoid overheating issues since there's very little movement of the bearings. None the less, the suspension has enough up and down travel to hopefully cycle the bearings throughout the cap and thus, I haven't cooked a u-joint yet. I have brute force and ignoranced one out of the yoke, but I've never actually cooked one, yet.

what you will probebly end up with is what's called gear rattle- it happends on a slight coast at 45 mph and above not on the gas and not off the gas - like a float - as for the wear life it does have an affect running a c/v because the actual operating angle is 1/2 of what your real angle is split- Jess

Thanks, I was aware of the equal angle Theory, that's why I have the C-V to put in. According to Jess, I just need to get it in. (read below)

Actually I forgot to mention this: I pointed the rear pinion 1-2 degrees above the line of the X-fer case because in the future I plan to run a different engine/tranny/Xfer that Will be longer than my current set-up, and will be moved back in the frame. So I expect that when that set-up is installed I will either be pointing directly @ the X-fer case or 1-2 degrees below it.

That's good to know. At least now I can expect it, instead of driving down the road and going OH S#!T!!! WHAT WAS THAT!!!


Oh and Jess, any opinions on the comment of pointing the pinion directly at the X-fer case , or 1-2 degrees below it, while running a C-V'd driveline??
