I searched through the threads and found some good information but was looking for some direct feed back to my sitch. Here is the lowdown.
I found this thread an a fella on there said something about the angle needing to be between 26-30 degrees. My angle is 19 degrees currently measured from the flat spot on the flange on the rear of the housing.

I have the cheap SYE kit from RE and CV Drive shaft. My pinion angle is at 19 degrees now and I am getting vibs. It's a very long story about how it go to be that way. I wheeled my suspension for probably about 2 years with no issues. Then the winter salt started to take it's toll on the spherical bearings in the CA's. One day I was toeing some heavy weight (another very long story) and my ujoint went in the drive shaft. I had the drive shaft rebuilt and rebalanced and all of the sudden I have vibs. So I went through loops and loops with the drive shaft I had it rebuilt and checked twice. My father had just passed away and I was moving my mom ... that is why I was towing heavy stuff around. After my dad passed I inherited some money and all of stuff to do. So I had a shop put 4.56 gears and a super 35 kit in for me. While they were in there I told them I think my pinion angle needs adjusting and they adjusted it for me (they messed it up). Vibs never went away. Ok that is the long story.
Now this is what I have done this year. I took the control arms out and found that the Spherical joints were messed up. They were seized and rusted beyond belief. PS I think this is where the vibs where coming from the whole time but I just didn't know it. So I rebuilt the whole suspension and have it all tight now. This brings me to today where I still have vibs. When I installed the lift I just adjusted my control arms to the length that they recommended and everything worked out well. So needless to say I never have known what the correct pinion angle should be.
Wheeeewwww .....
Can someone just put me at ease and give me some advise as to what my pinion angle should be?
I did a frame of on my first jeep (a 79 CJ7) and never had to mess with the pinion angle on that either (I threw this in so you all don't think the TJ is my first venture in to the world of jeeps). I have had allot of experience with bolting things on and building things up. Not much fab ... I just got a MIG so that will change now. And I just got a garage so no more layin in the driveway and running in and out of the house.
Well I'm off to take off the upper control arms and see if I can adjust them out a bit.
Thanks
