Wheels/Tires - Hard Metallic Knock from Front Wheel Bearing Are Mercedes Benz Truck ML 63 AMG
2010 Mercedes Benz Truck ML 63 AMG (164.177) V8-6.3L (156.980) Maintenance: By Symptom Wheels/Tires - Hard Metallic Knock from Front Wheel Bearing Are Hard, metallic knock from area of wheel bearing on front axle when cornering slowly or while parking Topic number L133.25-P-051401 Version 1 Design group 33.25 Axle housing, stub axle Date 04-09-2013 Validity Model 164 as of VIN 164 ###.#A 557 500 Model 251 as of VIN 251 ### #A104835 Reason for change Complaint: When negotiating a gentle corner at walking pace (5-8 km/h) or while parking / maneuvering, a single, loud metallic knock is heard from the area of the wheel bearing on the front axle. Cause: Wheel bearing bore in steering knuckle may not have sufficient press fit, therefore insufficient overlap between wheel bearing outer race and steering knuckle. Micro-movements result in the relevant noises. Remedy: Replace steering knuckle with wheel bearing. In the case of follow-up repairs (steering knuckle already replaced), only replace the wheel bearing and secure it using "Loctite 648" Note : Use the Chassis Ear to facilitate diagnosis. Experience has shown that in many cases the noise is caused only by the steering knuckle on the left-hand side in the direction of travel. For this reason repair the left-hand side first. To date we are only aware of problems occurring on vehicles produced from October 2009 onwards.
