Q: Clunking noise hear it at speeds of 35-40 loud

asked by on May 23, 2017

There is a clunking noise you hear at 35-40mph. Mechanic at Dealer don't know what it is. Wheel bearing been changed, bushing been greased

My car has 16900 miles.
My car has an automatic transmission.

Hi There, What you are describing sounds like a bad or worn out ball joint. A ball joint is designed to pivot through multiple planes. Of course, because the ball joint constantly pivots at different angles, it tends to wear out more rapidly than bushings. A load-bearing ball joint supports the weight of the vehicle, while providing a hinge point for the steering system. Load-bearing ball joints are designed to cancel the effects of normal wear by centering themselves in their sockets. Non-load-bearing ball joints, on the other hand, maintain precise dimensional tolerances in a steering or suspension system. Wear in a non-load-bearing ball joint will cause a noticeable change in the camber, caster or toe angle of a front suspension. Consequently, non-load-bearing joints are preloaded to compensate for wear. Common symptoms of worn out ball joints are clunking noises, excessive vibration, steering wander and squeaking. I would recommend having an expert from YourMechanic come to your location to diagnose and replace the ball joints on your vehicle.
