Why does the steering wheel shake when driving fast?

[Minnie]

Here are the reasons why the steering wheel shakes when driving fast: 1. It is a manifestation of poor wheel dynamic balance. Go to the after-sales service for a dynamic balance check. 2. Check whether the front and rear shock-absorbing support rubber blocks of the engine and transmission are normal. Go to the after-sales service for inspection and repair. Additional information: 1. Dynamic balance: If the shaking occurs at 80-120 mph and disappears above or below this range, the four-wheel dynamic balance should be checked first. Possible causes include the detachment of tire balance weights, failure to perform dynamic balance after tire repair, or inaccurate measurements by dynamic balance machines in some small roadside shops. 2. Tires and rims: The deformation of tires and rims is usually caused by careless driving habits, such as driving too fast on rough roads, climbing curbs, or passing over speed bumps at high speeds, all of which can lead to this issue.
