How to Solve the Steering Gear Noise Issue in Mercedes-Benz?
2 Answers
Here are the specific causes and solutions for steering gear noise in Mercedes-Benz: 1. Friction between the steering column and floor mat: If the noise comes from below the steering wheel when turning, check the steering column and car floor mat. An oversized aftermarket floor mat may directly contact the steering column, causing friction noise due to lack of lubrication. Applying lubricant can solve this issue. 2. Lack of oil in the shock absorber plane bearing: If the noise comes from outside the car when turning, it might be due to insufficient oil in the shock absorber plane bearing. Open the hood and listen if the noise comes from the shock absorber top mount. If confirmed, applying grease can help; if the noise persists, replacement is necessary. 3. Loose stabilizer bar bushing: Check if the stabilizer bar bushing is loose or damaged. A loose or damaged bushing can cause noise not only when turning but also on uneven roads. Tightening with shims can fix a loose bushing, while a damaged one requires replacement.
I noticed abnormal noises from the Mercedes-Benz steering gear, which requires serious attention. There could be multiple causes, such as insufficient or aged power steering fluid causing a whining sound during pump operation; or worn steering tie rods/universal joints producing clicking sounds when turning; even loose wheel hub bearings can generate noise. For initial DIY troubleshooting: Pop the hood to check power steering fluid level - if below minimum, try topping up with fresh fluid. Always use manufacturer-recommended fluid, as mixing types may worsen issues. If no improvement, inspect steering components for looseness or wear signs - like shaking tie rods to listen for play. Regular fluid changes and scheduled maintenance prevent problems. For severe noises, promptly visit professional repair shops - their diagnostic tools pinpoint issues accurately, avoiding driving hazards. Mercedes vehicles demand precision; negligence risks major failures.
