Steering wheel shakes profusely if you go over 50mph What is wrong with it?

Potential Causes of Steering Wheel Shaking at High Speeds:

1. Unbalanced Tires:

- This is the most common cause.

- It occurs when the weight of the tire and wheel is unevenly distributed, causing vibrations at specific speeds.

- Get the tires balanced by a professional.

2. Wheel Alignment Issues:

- If your wheels are not aligned properly, it can cause the steering wheel to shake.

- Have the wheel alignment checked and corrected if necessary.

3. Worn Suspension Components:

- Worn parts in the suspension system such as tie-rods, ball joints, or control arm bushings can cause shaking at various speeds.

- Inspect and replace worn components.

4. Brake Rotors Warping:

- Warped brake rotors can shake the steering wheel when braking or even while driving.

- Have the brake rotors checked and replaced if necessary.

5. Damaged Rims:

- If the rims are damaged or bent, they can cause the steering wheel to shake at high speeds.

- Check for bent rims and have them repaired or replaced.

6. Driveshaft Issues:

- Problems with the driveshaft or universal joints can also lead to shaking at certain speeds.

- Check the driveshaft and repair/replace any damaged components.

7. Loose Steering Components:

- Inspect the steering rack, steering column, and other related parts for any looseness or damage.

- Tighten or repair loose components.

8. Engine Misfire:

- If one of the engine cylinders is misfiring, it can cause vibrations that are transmitted to the steering wheel.

- Check for engine issues using diagnostic tools.

9. Faulty CV(Constant Velocity) Joints:

- Worn CV joints can lead to shaking at different speeds, particularly when accelerating.

- Inspect the CV joints and replace them if needed.

10. Transmission Problems:

- Issues within the transmission, such as faulty mounts or a damaged torque converter, can cause vibrations.

- Have transmission issues diagnosed by a qualified mechanic.

11. Differential Problems:

- A faulty differential (the component that distributes power between the wheels) can cause vibrations.

- Have the differential checked by a professional.

12. Poor Road Conditions:

- In rare cases, rough or uneven road surfaces can cause temporary shaking.

If you are unsure of the cause, do not disregard the issue. Have the vehicle checked by a qualified mechanic to ensure safe driving conditions.
