What Causes Vehicle Body Shaking During High-Speed Driving?
2 Answers
Reasons for vehicle body shaking during high-speed driving: 1. Inaccurate front wheel alignment angle, excessive toe-in; 2. Low tire pressure or tire imbalance caused by repairs or other reasons; 3. Front wheel rim deformation or unequal number of tire bolts; 4. Loose installation of transmission system components; 5. Bent drive shaft, dynamic imbalance, deformed front axle; 6. Failed shock absorbers, inconsistent stiffness of front leaf springs, deformed frame; 7. When the automatic transmission lock-up clutch and torque converter are locked, the engine power output and transmission input become rigidly connected. If not released promptly during braking, the transmission will drag and brake the engine, causing vibration.
I've experienced body shaking several times while driving on the highway, which is usually caused by tire imbalance. When your speed exceeds 100 km/h, if the tires are unevenly worn or not properly balanced, the car will shake like it's dancing. Sometimes wheel hub deformation can also cause this, especially if you often drive on rough roads. Problems with the suspension system, such as damaged shock absorbers or loose linkages, can also exacerbate the shaking. If the drive shaft is bent, it's more prone to issues at high speeds. It's recommended to slow down and pull over for inspection as soon as you notice shaking to prevent the danger from escalating. Personally, I get my tires balanced every time I experience shaking, and it solves the problem quickly. Regular maintenance, paying attention to tire pressure and wear, can effectively prevent these issues. After all, safety on the highway comes first—don't gamble with your life.
