Common Causes of Steering Wheel Noise in BMW E90
If you’re experiencing a strange noise while turning or a buzzing sound when turning the steering wheel in your BMW E90, there are several common causes that could be the culprit.
Tie rods and sway bar stabilizers
One possible cause is worn tie rods or sway bar stabilizers. These components can become loose or worn out over time, leading to noise when the steering wheel is turned. Regular inspection and maintenance can help prevent this issue.
Faulty steering rack or column
Another potential cause of steering wheel noise is a faulty steering rack or column. This can result in knocking or clicking sounds. If you suspect this is the issue, it’s important to have it diagnosed and repaired by a qualified mechanic.
Steering wheel trim and slip ring
The steering wheel trim or slip ring could be rubbing against other parts, causing a squeaking noise. Checking and adjusting the trim, as well as applying a lubricant to the slip ring, may help alleviate the noise.
By identifying the specific cause of the noise, you can take the necessary steps to address the issue and enjoy a quieter driving experience in your BMW E90.
Lubricating the Steering Spindle Bearings
One common fix for steering wheel noise in BMW E90 models is to lubricate the steering spindle bearings. These bearings, located at the bottom and top of the steering spindle, can become dry and cause squeaking or creaking sounds. To lubricate the bearings, the car needs to be jacked up, and a lubricant spray with a long flexible tube can be used to reach the bearings. Tri-Flow or a similar penetrating lubricant is recommended. It’s important to thoroughly coat the bearings and manipulate them to ensure the lubricant is distributed evenly. This can help reduce or eliminate the noise.
Regular lubrication of the steering spindle bearings can be a preventive measure to keep them in good condition and prevent noise from developing. It is recommended to include this task as part of routine maintenance for BMW E90 vehicles.
Procedure for Lubricating Steering Spindle Bearings:
- Jack up the car and secure it with jack stands for safety.
- Locate the steering spindle bearings at the bottom and top of the steering spindle. They will be visible once the protective covers are removed.
- Use a lubricant spray with a long flexible tube to reach the bearings. Tri-Flow or a similar penetrating lubricant is recommended.
- Thoroughly coat the bearings with the lubricant, ensuring all surfaces are covered.
- Manipulate the bearings by turning the steering wheel back and forth to distribute the lubricant evenly.
- Once the lubricant is applied, reassemble any protective covers that were removed.
- Lower the car from the jack stands and test the steering wheel for any remaining noise. If the noise persists, further investigation may be required.
By following these steps, you can effectively lubricate the steering spindle bearings in your BMW E90 and mitigate steering wheel noise issues.
Checking and Adjusting the Steering Wheel Trim and Slip Ring
If you’re experiencing grinding or clicking noises when turning the steering wheel in your BMW E90, one potential solution is to check and adjust the steering wheel trim and slip ring. Over time, the steering wheel trim can rub against other parts, causing unnecessary friction and noise. By inspecting the trim for any signs of rubbing or damage and making necessary adjustments, you can help alleviate the noise and improve your driving experience.
Additionally, applying a light coating of copper paste lubricant to the slip ring can help reduce friction and prevent noise. The slip ring is an electrical connector located behind the steering wheel, and lubricating it can ensure smooth operation and minimize any clicking or grinding sounds.
It’s important to follow the proper procedures outlined in the Bentley manual when removing and reinstalling the steering wheel to access the trim and slip ring. This will help ensure that the adjustments are made correctly and safely.
Table: Steps to Check and Adjust Steering Wheel Trim and Slip Ring
| Steps | Description |
|---|---|
| 1 | Safely jack up the vehicle and remove the necessary components to access the steering wheel. |
| 2 | Inspect the steering wheel trim for any signs of rubbing or damage. Make adjustments as needed to ensure it doesn’t contact other parts. |
| 3 | Apply a light coating of copper paste lubricant to the slip ring to reduce friction and prevent noise. |
| 4 | Reinstall the steering wheel and other components following the proper procedures outlined in the Bentley manual. |
By following these steps and ensuring that the steering wheel trim and slip ring are properly adjusted and lubricated, you can potentially eliminate grinding and clicking noises when turning the steering wheel in your BMW E90.
Replacing Worn Components
If lubricating the steering spindle bearings and adjusting the steering wheel trim and slip ring do not resolve the steering wheel noise, it may be necessary to replace worn components. This could include the tie rods, sway bar stabilizers, or even the entire steering rack or column. Consulting a qualified BMW technician or mechanic is recommended to accurately diagnose the issue and determine the appropriate replacement parts needed. It’s important to address worn components promptly to prevent further damage and ensure smooth and quiet steering.
When it comes to solving the screeching noise when turning the steering wheel on your BMW E90, replacing worn components is sometimes the only solution. Over time, the tie rods, sway bar stabilizers, and other steering components can wear out, leading to excessive noise and potential safety issues. If lubricating the steering spindle bearings and adjusting the steering wheel trim and slip ring do not alleviate the noise, it’s crucial to consult a qualified professional to accurately diagnose the problem and determine which components need to be replaced.
