Jeep squeaking while rolling?

So I attempted to adjust my castor last night on my pr44 unlimited. I ended up turning my upper control arms clockwise 2 full rotations. This made my pinion point to the ground just a hair if hardly any. I drove it home everything seems good when I was pulling in the parking lot I heard a pretty bad squeaking as I was rolling only does it when I'm moving. It sounds like my drive shaft or something I'm not sure though I'm running coast 1310 front and rear drive shafts. Any thoughts?

If I understand correctly you set your pinion angle and 0* or maybe even negative if itís pointing at the ground a little. If your pinion is at 0* on your prorock unlimited your caster will be at 10*. Not sure why you would want that? What size lift do you have? If you have much lift and your pinion is set at 0* your likely getting some driveline vibrations, not sure about the squeaking though.

What was your goal when you adjusted youíre your control arms? More caster? Less caster, pinion angle?

if you have the PR Unlimited, why did you adjust your pinion angle? are you running a huge lift? The PR44 Unl already has positive castor built in and the brackets are mounted to adjust pinion angle for 2.5" + lift.

I would adjust my control arms back and see if the noise goes away. What size lift? Auto? stock transmission skid? A large lift with the stock auto trans skid has been know to cause rubbing, but I doubt that's it (this usually happens when the front axle droops when wheeling).
