I have a drone coming from the frontend of my truck. It is really noticable above 60 mph. It seems to go away when making a tight right turn at speed. I checked it today and can only guess maybe a u-joint is getting bad or my right front tire has slipped a belt. Tires are Cooper with about 38,000 miles on them and they get rotated every 10,000 miles, tread is still very good. Everthing appears tight, no vibration and steering is tight for a truck with 139,000 miles. Any help appreciated.
