what did you measure?

 

I jacked it up the rear on the diff and then measured the distance between the top of the rim and the fender

 

When the truck is on the ground, the left side is 1.5" lower and when I jack it up on the differential it is 0.5" lower.

 

Before you throw parts at it measure all 4 corners. Watch the video I posted above, clear explanation front or rear.

 

Thanks Hummerz - I watched the vid last night and measured everything. I'm pretty confident it's the rear. I've already replaced the shock absorbers and when I'm on the highway and hit a bump the a$$ end rolls like a mf from side to side. Also, at 15-20mph, it's constant bumping up and down like a bouncy ball. On the way home from work today I heard a squeak from the left side when making a slight left turn with a bump. It's either the shocks, springs, or tires (right?). I've eliminated two of the three. I think I'm gonna bite the bullet and do it.

 

Shocks have nothing to do with ride height. Measure all 4 corners! Most common issue unlevel:

 

Could the Tbars cause the bad sway/roll on the highway?

 

 

Measure center rim to fender on all 4 corners and post the results:
