Why Does the Steering Wheel Feel Loose and Shaky on Rough Roads?

[Greg]

The reasons for a loose and shaky steering wheel on rough roads are as follows: 1. Excessive braking force: Frequent hard braking causes the brake discs and brake pads to overheat, leading to deformation when cooled, which results in steering wheel vibration. This issue is usually resolved after replacing the brake discs and brake pads. 2. Worn or loose tie rod ball joints or detached rubber bushings at the joints: Additionally, irregular tire wear can contribute to the problem. It is recommended to have a professional inspection at a repair shop and replace any damaged components. 3. Twisted or deformed drive shaft: Or loose, dry, or rusted universal joints on the drive shaft. Since these components are located beneath the vehicle, they are often overlooked during maintenance. Therefore, during each maintenance session, ensure that the service personnel apply grease to all applicable lubrication points.
