pinion angle???

[jamesgeologist]

You can run zero to slightly negative castor to bring your pinion angle up, however you risk uneven wear of your tires and poor handling on the street. Your steering will not return to center without your input and you will find every groove in the pavement. When I went to a 6" lift and custom control arms, I adjusted the uppers out so the pinion pointed at the t-case. Like I said, it'll solve the ugly driveline vibes, but there are trade offs. You may want to look into having your knuckles cut and turned so you keep -7 degrees of castor and your pinion points in the right direction. The fact that you have solid shafts in the axle shouldn't cause your problems. You notice it now because the d-shaft is spinning now when it wasn't before. Every Cherokee/Wrangler/Grand that doesn't have the vacuum disconnect has to go down the road with the front d-shaft spinning somehow....and none of them have manual hubs. Change the pinion angle and it will solve your problem!!

If you're going to the expense/trouble to cut and rotate your knuckles, do yourself a favor and swap out the 30.

I knew my superior powers of observation would come in handy one day!!

When you run a CV, the pinion angle at the axle must have a -0- angle on it. Meaning that the pinion must point directly at the T case.

Yes, you are getting vibs due to this angle.

Wow, I didn't know you were a driveline guy???? 3 degrees down max on the u-joint, 0 is ok with a link suspension but may need to fine tune it.

And I thought you were a skiier...

If you put the pinion where it's supposed to be your caster should be ok. I had a long talk with a few people who have experimented alot with the XJ,TJ,blah blah blah. Anyways, with your tire size you can actually roll the pinion up and still have good alignment.
