Here are some of the reasons why the steering wheel and dashboard may shake when you are in reverse with your foot on the brake:
* Drivetrain components: When you put the car in reverse, the gears in the transmission engage and the driveshaft begins to rotate in the opposite direction. This can cause a slight vibration in the drivetrain, which can be felt through the steering wheel and dashboard.
* Engine mounts: The engine mounts are designed to absorb vibrations from the engine. However, if the engine mounts are worn or damaged, they may not be able to absorb the vibrations effectively, which can cause the steering wheel and dashboard to shake.
* Transmission fluid: If the transmission fluid is low or dirty, it can cause the gears in the transmission to slip, which can also cause a vibration in the drivetrain.
* Wheel alignment: If the wheels are not aligned properly, it can cause the tires to wear unevenly, which can lead to a vibration in the steering wheel and dashboard.
If you are experiencing a shaking or vibration in the steering wheel and dashboard when you are in reverse with your foot on the brake, it is important to have the car inspected by a qualified mechanic as soon as possible to identify the cause and prevent any further damage to your vehicle.
