Strut Mount Bearing Noise – Clunk When Turning Explained

A clunk or click that appears only when turning the steering wheel at low speed is one of the most common front-end complaints, and the cause is almost never the power steering pump or the rack. The noise comes from the top strut mount bearing, which allows the strut to turn with the steering wheel. When that bearing wears out, every steering input produces a click or clunk that the driver hears in the cabin. The fix is usually inexpensive, but it is often misdiagnosed.

What the driver feels

A clunk or click when turning the steering wheel while parked or at low speed.
A noise that follows the direction of the steering wheel, left or right.
A slight stiffness when turning the wheel in one direction.
A groan or creak from the front end when turning into a driveway.
A click that appears when turning the wheel back to center.
Vibration felt through the steering wheel at low speed.
Uneven tire wear on the front shoulders.
A noise that gets worse in cold weather.

Why the mount bearing clicks

The top strut mount sits between the strut tower and the strut body. On a Toyota Camry or Honda Accord, the mount contains a bearing that lets the strut rotate as the steering wheel turns. The bearing is sealed and packed with grease from the factory, but after many years the grease dries out, the race wears, and the bearing develops play. Every steering input then produces a click as the worn race moves.

The noise is most noticeable at low speed because that is when the steering wheel moves slowly. On a Ford Focus or Nissan Altima, turning into a parking lot moves the steering wheel through several full turns, and each degree of rotation passes over the worn bearing race. At highway speed, the steering wheel only moves a few degrees, so the noise is absent. This is why the driver says the noise is only when parking, not when driving.

Diagnosing the strut mount noise

With the car parked and the engine off, turn the steering wheel left and right and listen for the click.
Have an assistant turn the wheel slowly while you put your hand on the strut tower to feel for the click.
Bounce the front corner up and down while listening for a clunk, which indicates a worn mount.
Inspect the top mount from the engine bay: look for cracks in the rubber and play at the center nut.
Compare left and right: the noisy side is the one with the worn bearing.
Safety note: With the engine off, power steering assist is gone, so the wheel will feel heavy. Keep feet clear of the front wheels.
Check the sway bar links at the same time, because they also clunk and are often confused with mount noise.
If the noise only appears when turning while driving slowly, it is almost certainly the strut mount bearing.

Replacing the strut mount

Replace the strut mount bearing in pairs on the same axle, because both sides wear at the same rate.
If the struts are also over 80,000 miles, replace the whole strut assembly including the mount at the same time.
When replacing just the mount, the spring still has to be compressed, so budget for the shop labor.
Torque the center nut to specification at ride height, not on the lift, to avoid pre-loading the bearing.
After the job, test the steering wheel left and right to confirm the click is gone before the car leaves the shop.
