Can a wheel alignment fix vibration?

Wheel misalignment

Another common cause of steering wheel vibration is the incorrect positioning of the wheels. In most cases, a wheel alignment will stop the shaking by ensuring all wheels are positioned in the same direction. One of the quickest ways to diagnose misalignment is to check the tire's tread.

Can alignment cause vibration at high speeds?

Failing wheel bearings also often cause the affected wheel to wobble back and forth while moving.

How is a car vibration diagnosed?

What do Unbalanced tires feel like?

Balancing also contributes to ride comfort: Imbalanced tires will wobble or hop up and down, which causes vibration. If a front tire isn't properly balanced you'll likely feel vibration in the steering wheel. If the problem is in the rear the tremor will be noticeable in the seat or floor.

Can a transmission cause vibration?

Grinding, Shaking and Other Bad Vibrations

An automatic transmission is more subtle in its signals, but they are unmistakable. Transitions into gear and between gears will cause some vibration at first; but then, as the problem persists, gear changes become more jarring and cause shaking.
