Slight Tire Rubbing -- Caster Question

[Johnny4runner]

Do I need to increase my caster to avoid tire rubbing? And if so, can I just dial in +2* more caster with my LR UCA (via the upper ball joint adjustment), or should I go back to the shop for a complete alignment? Or both--dial in +2* more and take it back and ask for more caster. The current setting of the LR UCAs is +2*, in addition to the +2* built into the LR UCAs. How high should I go on the caster, a total of +4* or more? Or should I just cut off the offending portion of the body cladding that is rubbing?

I lifted my 4Runner about a year ago and for the most part everything is great. But I still get some rubbing at the rear of the wheel well on compression with the wheels turned--usually the driver's side. The rubbing is on the bottom corner of the body cladding (not the body mount which has already been chopped). Definitely not a problem most of the time, but it can be annoying when caught in an odd position off-road. I'm lifted about 3" in front and running 285/70/17 GY DT (great tires BTW).

Increasing caster through the UBJ will create MORE rubbing in the rear, as it will move your tire back. I would first try to take the UBJ back to the neutral position +0 and then get as much caster as you can out of the LCA. The LCA caster adjustment will rock the knuckle away from the rear where the UCA adjustment rocks it back. Most of us are able to get caster within spec without adding any through the UCA adjustment. If that doesn't get you enough clearance, which I suspect that it might not. Most of us trim out the inner fender for clearance. Hope that made sense and helps. Good luck.
