Hmm, I never thought of that. I used what I believe to be 4wd rear UCA’s. That would be why it made the symptoms a lot worse. I guess the control arms would need to be shorter than stock rather than longer which is what these are.

Its funny you mention that, because I can’t tell if maybe the caps on the UJ aren’t the right size or if its like what you said, but I swear I saw the cap move around in the yoke a little bit, and as I think back to it I remember those caps sliding in a little too well, I originally thought it was because we had put them in the freezer.

I had my drive shaft completely rebuilt and balanced, didn't help.
Balanced my tires on Hunter road force machine, didn't help.
Finally replaced upper and lower rear control arms, adjustable on both. Lined up rear pinion angle with drive shaft to with 1 degrees. Now it can go up to 100 MPH and it's smooth as silk.

I guess I don’t know enough about driveline geometry evidently. I will be trying 2 things next before I bite the bullet on that one. 1) put in new, reliable UJ’s from Moog, and 2) get an aftermarket DS from those Texas Driveshaft Specialist guys, I don’t care much for the OEM driveshaft, and if the yokes are worn out then it doesn’t matter how many UJ’s I put in and times I adjust the pinion angle. All else fails, Any aftermarket 2wd control arms you would recommend?
