What Causes the Squeaking Noise When Turning the A6L Steering Wheel?
1 Answers
If there is abnormal noise when turning the steering wheel and the steering feel is noticeably uneven, it may be due to excessive clearance caused by wear in the steering gear's meshing gears. Replacing the steering gear should resolve the issue. Other possible causes of steering wheel noise include: 1. Friction Between Plastic Components: Friction between plastic components can cause steering wheel noise. The steering wheel is composed of various plastic parts, and if the gaps are too small during rotation, abnormal noise may occur. This is especially common in new cars and usually improves after a break-in period. If the noise persists after break-in, try reinstalling the steering wheel. Another possibility is friction between the airbag clock spring and the steering column. This could be due to manufacturing or assembly issues. Owners who have disassembled the steering wheel should pay extra attention, as it might indicate a broken airbag clock spring or a loose connector. Replacing the clock spring or securing the connector can fix the problem. 2. Direct Friction Between Limit Screw and Limit Device: The limit screw has a protective nylon sleeve that can wear out over time. Without this sleeve, when the steering wheel is turned to its limit, the metal-on-metal contact between the limit screw and the limit device produces a squeaking sound. It is recommended to replace the limit screw or apply grease to it for temporary noise reduction. Additionally, steering wheel or column noise may be temperature-related, as thermal expansion and contraction can cause friction between plastic components.
