What Causes High-Speed Vehicle Body Vibration?
2 Answers
High-speed vehicle body vibration can be attributed to the following 5 causes: 1. Incorrect front wheel alignment angles, excessive toe-in. 2. Low front tire pressure or tire imbalance caused by repairs or other factors. 3. Deformed front wheel rims or incorrect number of tire bolts. 4. Loose installation of transmission system components, bent drive shaft, power imbalance, or deformed front axle. 5. Failed shock absorbers or inconsistent stiffness of front leaf springs. When vibration occurs at higher speeds and causes steering wheel shake, you can first lift the drive axle and place safety blocks under the front wheels. Start the engine and gradually shift into higher gears.
I once experienced severe body shaking at high speeds, which turned out to be a tire issue. Uneven tire wear or incorrect tire pressure (either too low or too high) can cause imbalance. Additionally, deformed axles or aging suspension components like shock absorbers can amplify vibrations at high speeds. It's advisable to check tire pressure before every highway trip and maintain consistent standard values. If you feel shaking, immediately reduce speed and stop to inspect the wheels for obvious wear or foreign objects. Don't ignore such minor issues, as they may damage other components and increase repair costs. I once wasted money on a major suspension system overhaul. Pay more attention to wheel balance and suspension condition during routine maintenance—prevention is much more convenient than post-failure repairs. Safety comes first; highway accidents can be disastrous.
