What Causes Vehicle Body Shaking at High Speeds?

[CarolineMarie]

Vehicle body shaking at high speeds is caused by: 1. Unbalanced wheels: Wheel imbalance is a common issue in many vehicles. During manufacturing, it's impossible to ensure perfect mass distribution in tires and rims. Worn tires can cause rotational imbalance, leading to body shaking; 2. Excessive steering gear clearance: Over time, wear between rack and pinion gears creates play, resulting in body vibration; 3. Loose suspension components: Suspension parts are connected via ball joints and rubber bushings, but as these wear out, components become loose, making the suspension sloppy and causing body shaking during driving.
