I purchased a 98 wrangler with a 4" lift. It has 35x12.5r15 tires on it. This think is all over the road! Have replaced steering stabilizer and one front axle u-joint. Is it just the wide tires in the grooves in the road that is doing it? Any ideas? Thinking of moving to 10.5 to see if it makes a difference. Its time for tires anyways.
