What Causes the Front Wheels to Make a Thumping Noise When Driving on Rough Roads?
2 Answers
The reasons for the front wheels making a thumping noise when driving on rough roads are: 1. The shock absorber of the left front wheel is damaged; 2. The top rubber of the left front wheel shock absorber is damaged; 3. The lower control arm of the left front wheel suspension is faulty. The functions of tires are: 1. To transmit driving force, braking force, and steering force to achieve vehicle operation; 2. To support the vehicle load; 3. To reduce and absorb vibrations and impacts during driving, avoiding severe vibrations that could damage vehicle components. Methods for tire maintenance include: 1. Regularly cleaning stones stuck in the tire treads; 2. Minimizing exposure to direct sunlight; 3. Promptly checking tire pressure; 4. Paying attention to suspension maintenance; 5. Regularly inspecting front wheel alignment; 6. Being mindful of driving habits, such as choosing smooth roads and avoiding objects that could puncture or scratch the tires, as well as chemical spills that could corrode the tires.
I've been driving for decades, and the thumping noise from the front wheels on rough roads is a common issue. The most frequent cause is worn-out or leaking shock absorbers, which fail to absorb bumps, resulting in direct metal-to-metal contact and noise. It could also be due to loose suspension ball joints, worn tie rods, or wheel hub bearing problems. I remember last year when my car kept making noise, and the inspection revealed a completely detached ball joint – it was almost a disaster. For safety's sake, don't push your luck; get it checked by a professional immediately. Overinflated or underinflated tires can also worsen the noise, so developing a regular maintenance routine is crucial. Newer cars might be more durable, but older vehicles require extra attention to the suspension system – fixing issues early brings peace of mind.
