thumping noise Sign In

i have an 04 chevy silverado 1/2 ton 4x4 on 35 in. tires. it started going thump thump thump repeatedly while driving down the highway. it slows down as the truck slows down and gets faster as the truck gets faster. it has 86,000 miles. it still runs fine so its not in the motor. any suggestions would be helpful.

Are the tires brand new? A unevenly worn tire will cause what you are describing. Espcially on a 35 inch tire.

the tires are about 6 months old. there is no uneven wear and they look fine.
