LR UCA Install Rubbing Issue

I just got my 3" Pro Comp lift installed. Had stock UCA for about a week and it drove fine with little to no rubbing. Tuesday I had LR UCA installed and now my rubbing is much worse than before. Here's the specs:

Wheel specs: 275/70/r18

and Alignment specs are
Front left -0.2 Camber
Front left 2.4 Caster
Front left 0.07 Toe

Front Right -0.2 Camber
Front Right 2.8 Caster
Front Right 0.05 Toe

Any help will be much appreciated. The rubbing happens when I turn about 45 degrees and go up driveway or hit any dips. it rubs on the back body mount. Also, when in reverse, I turn the wheels to the left and reverse, the front right tire rubs? I can feel it vibrating the truck...Not fun. Not sure what to do from here. More Caster? I read somewhere that 3.3-4 Caster is less likely to rub the back body mount. Help!

 

yeah, go get your caster closer to 3 and you should be fine.

 

I'd just trim fenders a tad. Otherwise you have to mess with the caster settings of that ball joint and it'll require a new alignment.

 

+1...My dealership adjusted the caster when I went and had my truck aligned about 6 monsths. I knew something was wrong when I was rubbing the rear mount more. I have the LR UCA's and 285/65/18's.

 

Would 3.3 Caster be too much? I am thinking that Caster at 3 might still rub. How much difference in inches is it with a +.5 caster change?

 

I cut the fenders on the front already. But the rubbing is on the body mount. Metal on the back side of the inner fender.

 

Do you know what your Alignment specs were after the dealership adjusted it? This way I can get a better idea of what to set it at.

 

I know alot of guys have there Caster at 3 or 2.8.. And they are running 285's with no issues... But they also got wheels with a 4.5" BS...

 

body mount is easy enough to cut as well.

 

yeah just use a hand grinder and it should take care of it.
