The GMB Wheel Bearing Hub Assembly is a direct-fit replacement for Mercedes-Benz C-Class models built from 2016 to 2019. All seals, clips, grease and hardware needed for the fitment are supplied in the kit. Fit with a press and the correct drift; hammering the assembly will damage the new bearing. Symptoms of failure usually include a hum that changes with cornering load, or vibration under acceleration. The assembly is built to original equipment tolerance with pre-set bearing preload where applicable. The Steel component is heat treated for wear resistance and fatigue life under load. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. Every unit is supplied new with a 12 Months warranty against manufacturing defect.
