What are the causes of shaking during acceleration from 80 to 100 and when pressing the accelerator?

[LeMalia]

Shaking during acceleration from 80 to 100 and when pressing the accelerator is mainly caused by issues with wheel dynamic balance and wheel alignment deviation. The details of these two causes are as follows: 1. Wheel dynamic balance issue: Dynamic balance is a necessary adjustment for every vehicle. If the dynamic balance of the four wheels is disrupted, the vehicle will experience shaking or bumping problems at high speeds. 2. Wheel alignment deviation: After the vehicle has been driven for a period of time, the alignment of the four wheels may deviate, causing changes in the camber and toe angles of the tires, which significantly reduces the vehicle's driving stability.
