BMW 7-Series Steering Wheel Shaking & Vibrating (Causes & Fixes)

Updated: Jan 9

The most common causes of a shaking steering wheel in a BMW 7 Series include unbalanced wheels, misaligned wheels, tyre damage, bent rims, defective wheel bearings, worn engine mounts, and loose lug nuts.


Damaged suspension or steering components, as well as excess or under-inflated tyre pressure, are less common causes.


The 7 Series is a very big and heavy car that is vulnerable to strong impact forces from potholes, curbs, and so on, and its suspension components, wheels, and tyres are easily damaged.

Causes of Steering Wheel Shaking in a 7-Series

There are many causes of steering wheel shaking and wobbling in your BMW.


Always start your inspection with the most evident issues, such as imbalanced or out-of-alignment wheels. A good starting point is to inspect the rims and tyres for apparent signs of damage.


Uncommon causes of steering wheel shaking include:

  • Suspension and steering components that have been damaged

  • Tyres that are under-inflated or over-inflated

  • Uneven tyre wear

  • Damaged driveshaft


To resolve this problem, take your 7-Series to a garage or tyre shop for professional advice.


BMW Steering Wheel Vibration at Idle

There are several potential causes for steering wheel vibration at idle in a BMW.


One possible culprit is a faulty A/C compressor. The A/C compressor is responsible for pumping refrigerant through the air conditioning system, and if it's not functioning properly, it can cause vibration.


Another potential cause is a faulty belt or chain, such as a timing belt or auxiliary belt. These belts and chains are responsible for driving various engine components and if they're damaged or malfunctioning, they can cause vibration.


Another possible cause of steering wheel vibration at idle in a BMW is damaged engine mounts. Engine mounts are responsible for securing the engine to the frame of the vehicle, and if they're damaged or worn out, they can cause vibration.


Faulty fuel injectors can also cause steering wheel vibration at idle. Fuel injectors are responsible for delivering fuel to the engine, and if they're not functioning properly, it can cause vibration.


If you're experiencing steering wheel vibration at idle in your BMW, it's important to have it diagnosed and repaired as soon as possible. Ignoring the problem can lead to further damage to your vehicle and can potentially compromise your safety on the road.


Imbalanced Wheels

Poorly balanced wheels are a common source of steering wheel vibration in the BMW 7 Series, especially at high speeds.


  • When just the front wheels are out of balance, the vibration is generally most perceptible.

  • If the rear wheels are substantially out of balance, the whole body of the car will tremor.

  • If the front wheels are uneven, the steering wheel will wobble.


Causes of Improperly Balanced Wheels

Uneven tyre wear, potholes, and other road hazards may cause your wheels to become unbalanced. This produces an uneven shift in the tyre and rim's centre of gravity.


As a consequence of the wheel's vibration and the centrifugal force that occurs at high speeds, the steering wheel begins to tremor and wobble. In addition to the wheels, other elements of your car may see additional wear and tear.


Should New Tyres Be Balanced?

After installing new tyres, you should have the wheels properly balanced to minimise vibrations and premature wear caused by wheel imbalance.


How Wheels Are Balanced

Wheel balancers are specialised machines that are commonplace at most tyre shops and may be used to balance wheels by a professional technician.


  1. In a machine, the wheels are rotated while sensors monitor the rotation to calculate the imbalance.

  2. According to the computer, little weights are affixed to the inside barrel of the rim.

  3. These weights keep the wheel balanced and enable it to revolve smoothly.

Bent & Damaged Rims

A bent rim may also cause your BMW 7 Series' steering wheel to shake and vibrate.
