MDMH757 Posted 1 hour ago Share Posted 1 hour ago I recently acquired a 2017 Mercedes GLC 250d x253 with 50,000 miles from the original owner. The vehicle produces a ticking noise, which I have documented, when the steering wheel is turned to the left. I am uncertain whether this occurs when we turn right. I inadvertently captured it on camera. The vehicle occasionally exhibits a sensation of traversing an obstruction in the road while reversing with full or partial steering lock, and forum discussions suggest this phenomenon may be referred to as "crabbing."? I enquired with the original owner, who stated that warranty repair was performed to address the "crabbing" issue; yet, the problem appears to persist. Is there any information on a ticking noise when rotating the steering wheel, as well as a clunking sensation when reversing and turning? I have encountered discussions indicating that the problem may pertain to the steering knuckle, and that Mercedes might provide coverage due to it being a manufacturing defect. I possess a Mercedes extended warranty. Thank you for your attention. Quote Link to comment Share on other sites More sharing options...
Black_raven Posted 1 hour ago Share Posted 1 hour ago Winter tires or all-season tires are necessary to prevent crabbing. I installed XL tires on my GLC; a significant error. I refrain from fully locking the vehicle on cooler mornings. I will either install crossclimate tires or adapt to the current situation. Unable to assist with the ticking.

paulh2602601 Posted 1 hour ago Share Posted 1 hour ago The hub may require lubrication. Simple resolution. Remove the tyre, clean the interior of the alloy, apply grease to the hub and then reattach the tyre. Quote Link to comment Share on other sites More sharing options...

MotoGravity Posted 1 hour ago Share Posted 1 hour ago I am uncertain about the purpose of lubricating the hub or the origin of this concept. If it occurs solely at full lock, it is undoubtedly the tires slipping on the pavement due to the 4MATIC technology. Quote Link to comment Share on other sites More sharing options...
NAVITEL Posted 1 hour ago Share Posted 1 hour ago I possess a 2021 GLC equipped with Michelin Pilot Sport SUV tires (non-runflat) and have not seen this issue whatsoever. I suspect there was a modification for the suspension of certain earlier vehicles, but I cannot confirm this with certainty. I admire these vehicles; best of luck with yours.

MotoGravity Posted 1 hour ago Share Posted 1 hour ago Mercedes-Benz modified the steering knuckles circa 2019/2020. This altered the orientation of the front wheels. £500 for each side. Are your tires XL? Quote Link to comment Share on other sites More sharing options...
ElectricEclipse Posted 1 hour ago Share Posted 1 hour ago I possessed an Audi that exhibited similar behaviour. The brake pads (Mintex) were found to be ill-fitting, exhibiting significant looseness and movement within the calliper. It ceased when I applied the brakes, when I removed my foot. Generic pads from ECP resolved the issue. Quote Link to comment Share on other sites More sharing options...
