Rotate the front tires to the back on the same side. Also make sure you do not have a really loose front wheel bearing. Best test for the wheel bearing is to pull back and push the top of the wheel in and out and listen. Each side should be about equal. Deal with any abnormal clunk. Ocasionally someone previous did not seat the bearing races and they get pushed in after awhile creating too much bearing play. Both above easy, quick and cheap to check.
