Why does the front wheel of Audi A4L make abnormal noise when passing over speed bumps?

[LeRiley]

Audi A4L front wheel abnormal noise when passing over speed bumps may be due to the power steering belt of the left front wheel making noise; replace the belt. The second type of noise could be from the brake pads or a deformed metal piece behind the brake disc rubbing against it. Other reasons: There are many reasons for front wheel abnormal noise. A rhythmic sharp noise might be caused by friction from the brake pads being too close to the brake disc. Continuous sharp noises could indicate a damaged bearing, while continuous dull noises might suggest an issue with the drive shaft. Normal phenomenon: Some abnormal noises do not affect driving but are merely uncomfortable to hear, such as noises inside the cabin, which are usually caused by loose panels rubbing against each other.
