Noise – Thumping or Thudding Wheel Sound
by John Mosko
Description of Problem:
You hear a thud or a thump that comes from the wheel area and corresponds
to the rotation of the wheels and tires.
You likely have a bulge, bump, flat spot, or other issue with one of
the tires on the vehicle.
1. Inspect the tires. Generally speaking, the thud or thump coming from
the wheel area is usually indicative of a problem with one or more tires.
Look over the tires for any discernable issues including bumps, bubbles,
flat spots, or exposed steel wires. Tires can get these imperfections
or issues due to wear over time, or they can also be caused by trauma
such as hitting c chuck hole or curb and damaging the tire. If you find
any noticeable damage, switch the wheel for your spare and have the
tire replaced as soon as possible.
2. If your visual
inspection does not net any results, you will need to lift the car up
with a jack to inspect further or take the car to your mechanic. While
up on the jack, you should be able to freely rotate the tires and scan
them for flat spots or other issues you may not have been able to see
while the car was on the ground.
