I have a 99 F-250 SD 4x4 RABS and am having problems with RF brakes grabbing harder than the LF. I have replaced the following:

All front slide pins
Front Calipers
Front Caliper brackets
Rotors
Pads
Front flexible brake lines
Tires and wheels for winter


The RF wheel accumulates at least twice as much brake dust as the LF. Plus, the RF will flat spot a tire, unlike the LF.

 

check wheel bearings

 

I just did the RF with a new timken.

Could hitting a curb bend the knuckle? I hit it hard enough to knock the steering wheel off center, I'm not sure if I knocked the toe measurement off, as I did not see the alignement printout.
