knocking noise over bump
MAZDA 6 Hatchback (GH)

Features and types of knocking

It is unrealistic to understand the root cause of the knock in the front suspension on small bumps by sound. If you are careful while driving, you will notice some features:

1) A dull sound that appears on the left and right when the car shakes on bumps while driving. In this way, wear of the strut mount is manifested.

2) A knock when turning the steering wheel to the left and right side is present when the load on the broken shock absorber. These parts of the car usually fail one by one, and when you turn the steering wheel, this becomes clear.

3) A ringing knock on a flat road usually indicates a worn thrust bearing.

4) A severe squeak that appears while driving on gravel roads in front-wheel drive vehicles indicates a serious problem in the ball joints.

5) When a small fractional sound occurs when the machine overcomes irregularities, you need to revise the stabilizer bushings.

6) A knock in the front suspension when starting off often indicates that the suspension arms are not fully fixed.

7) When the car knocks when braking or picking up speed, more often the suspension has nothing to do with it, you need to check the engine mounts.
