Since pinion angle takes precedence over castor, I would think that if you had way to much positive castor that you would be getting some really bad driveline vibes front the front. Just get under there and make sure that the front diff is pointed straight at the t case input. My swaying on the highway issue was from worn out control arm bushings.

I do have bad vibes. I orders adjustable control arms as mine are fixed. When u say worn was there a lot of movement like a clunk or just soft

How many plies are the tires and what's your tire pressure set at? That will change everything to what the door says.

These were the originals when I bought it. 128,000 miles on a stock ZJ. Wandered all over the road. And felt like I had no shocks in the turns.

Yes, I just installed my new adjustable lower arms set my caster to 6.5 degrees and it helped a lot. It's drive able now but still sways a little bit. I am going to order adjustable uppers and new rear bushings to see if it will go away completely
