What Causes the Front of the Car to Shake?
2 Answers
The reasons for the front of the car shaking include: misalignment of the front wheel positioning angles, excessive toe-in; low tire pressure or imbalance caused by tire repairs; deformed wheel spokes or unequal number of tire bolts; loose installation of transmission system components; bent drive shaft, dynamic imbalance, deformed front axle; failed shock absorbers, inconsistent stiffness of front leaf springs, and deformed frame. Additional information: 1. Adjustment: Check whether the front wheel positioning angles and the front wheels meet the requirements. If misaligned, adjustments should be made; lift the front axle and test the rotation of the wheels to check the static balance of the wheels and whether the tires are excessively deformed. If necessary, replace with good wheels for comparison tests. 2. Shock Absorber: The shock absorber is a device designed to accelerate the attenuation of frame and body vibrations to improve the car's ride smoothness (comfort). Most cars' suspension systems are equipped with shock absorbers.
As a veteran driver with twenty years of experience, I've encountered the issue of car front-end shaking multiple times. Common causes include unbalanced tires, which cause strong vibrations at high speeds; deformed wheel rims, especially after hitting potholes; loose suspension systems or failed shock absorbers that increase bumpiness; bent steering rods that make the steering wheel vibrate; and damaged engine mounts that transmit engine shaking. Don't ignore minor shaking—it can affect handling at high speeds. First, slow down to a safe area, then visit a professional repair shop as soon as possible. Regular maintenance can prevent recurrence.
