So I have removed the mud flaps, chopped the cab mounts, folded the pinch weld, cut the fender metal, trimmed the fender plastic, and trimmed the fender liner. I still rub on compression with the wheel turned at various points, especially under full lock on the cab mount chop plate. Right now my lift and allignment stats are as follows.
American Racing Artillery 17x9 4.53" backspace -12mm offset
Nitto Trail Grappler 285/70R17 33.15" x 11.81"
OME 885x with trim packer below left coil
Desert Products Uniball UCA
TSB leaf with ICON 3 leaf add a leaf and overload removed
Caster 2.4 Left 2.6 Right
Camber 0.0 Left and Right
Tow .02 Left and Right
It seems to me the 2 degrees of posititve Caster from the Uniball UCA actually caused rubbing and that for the limited lift I have I did not really need it. Oh well... I'm not removing it.
To me this leaves only ONE thing I can do to move the wheel forward and stop rubbing. I have to add Caster to move the wheel forward in the wheel well.
My questions are these... how much does each degree of Caster move the wheel forward? How much Caster is too much? What happens as the wheel compresses if I add too much Caster?
I am estimating I need the front wheels about .25" more forward to get full clearance.
