What Causes the Clicking Sound When Turning a Mercedes-Benz?
3 Answers
If there is a sound when the steering wheel is turned to its limit, it is a normal phenomenon, as this sound originates from the steering gear. If not, it is recommended that the owner visit a service center to check whether the steering gear's clearance is within a reasonable range. It could also be due to loose screws or clips on the underbody guard, which can produce sounds when turning. Below is more information about Mercedes-Benz: 1.

Oh man, that clunking sound when turning the steering wheel on a Mercedes – I know exactly what you mean! My car had the same issue before, and the noise was downright unnerving. After taking it to the shop, I learned it's most likely due to loose tie rods or ball joints. Think of them like the joints in your arm – over time, the rubber boots age and crack, the grease inside leaks out, and then it's just metal grinding against metal, hence the clunking. It's especially noticeable during low-speed turns or going over speed bumps. If left unfixed, the steering play will keep increasing, making the car feel unstable. And if the boot completely fails, the steering could lock up – now that's seriously dangerous! Get your mechanic to lift the car and check for wheel wobble. If anything feels loose, replace it ASAP. Nowadays, they usually replace the tie rod and ball joint together as a complete assembly for convenience.
After all these years in the repair business, I've found that the clunking sound in Mercedes-Benz vehicles often points to genuine issues with the steering gear itself. Mercedes steering systems are incredibly precise, especially those with electronic power assistance. Inside, there are gear racks that, when severely worn or with loose mounting bolts, can cause excessive play during steering. This results in a loud 'clunk' as the rack hits the limit block, sounding like someone's tapping the chassis with a wooden stick. The noise might be less noticeable in summer but becomes pronounced in cold weather as the oil thickens. Another common scenario is a failed thrust bearing, where turning the wheel while stationary produces a sharp, spring-like 'ping' noise, reminiscent of a snapping spring. Neither of these issues should be tackled DIY—they require specialized tools for data calibration and should be diagnosed by a reputable specialist workshop.
