3 months ago now I put on pro comp leafs and to even it out decided that the cheapest way to level it out was to torque up the torshion bars. After
10K i now have the most annoying squeek comming from the driver front. The angle of the ball join is a bit to much and am pretty sure after spraying silicon on all the bushings that my problem is the severe angle. There was a place called sport truck out by me and are out of business now so I don't know who I can call on advice. If anyone can help please let me know because this squeek makes me go insane!!!

 

Ball Joint shot is my bet happened on my 2000 F150 about 5000 miles after 3" body lift and full crank on torsion with 35" tires. Looked good but ball joint was the issue for me lower one passenger and yes it will make you insane.

Good Luck.
Mike
