I'm w/ T R...........I've previously done alot of front end/alignment work as well. Let me try to put his statement another way; say [just guessing] the specs call for 5 deg positive camber each side with a tolerance of 1 deg plus or minus and 4 deg positive caster each side plus or minus 2 deg. For the sake of argument, they read as follows; R/S...........4.5 deg positive camber & 3.5 deg positive caster; L/S............4.2 deg positive camber & 4.5 deg positive caster. In theory, they are within tolerances. However, with the offsets all going right, the vehicle may want to pull that direction [1 deg caster off-set & 3/10 deg camber offset]. This is just an example; don't know what your actual numbers are. Point is, even if the numbers ' are in spec ', if you have large enough camber or caster offsets, or both, going in that direction, you may still get that pull. The rule of thumb we always went by w/ anything rear-wheel drive was camber offset as close to zero as possible and approx 1/2 deg caster offset going to the left, in theory, to compensate for any crown in the road. As far as the offset camber bushings on the upper ball joint; heck yeah, if your guy doesn't mind taking the time and you don't mind spending the money, great idea!!! They can tend to be a pain on the Dana's though. Also, with the tires, just one more suggestion; instead of back to front, try cross-rotating them [right to left, left to right]. Good luck!!!!!!!!!
