If you havent disturbed the steering wheel, (removed it) or the pitman arm on the steering box shaft. Jack both wheels up and scribe a line with a nail or awl down the center of each tire while rotating the tire. This gives you a line to measure from on each tire, then center the steering wheel up and lower the wheels back down while the steering wheel is held center. Measure the distance between the front tires at the front of the tires and the distance between the rear of the front tires. You should measure about a 1/16th to an 1/8th inch narrower at the front of the tires...Take a look at the front tires (while the steering wheel is centered) to see any noticeable misalignment of one or the other tire in relation to the rear tires...Thats how I align my front ends and I'm running 275/70/16's on one of my 72 C-10's with zero scrubbing and very little wear on two year old tires with 20K miles on them. I dont get any scrub or wheel hop like you described when I turn in either extreme...Wheres your steering wheel when your tracking straight down the road, is it centered?
