This bulletin applies to all Mercedes-Benz vehicles equipped with front-wheel drive and 4x4. A squeaking noise may be heard at the full steering lock at the front axle. The painting of the rubber boot during production can result in a squeaking noise at the outer joints at full lock.
Raise the vehicle on a hoist, then turn the steering wheel to full lock on both sides while rotating the wheels by hand. If there is a squeaking noise near the full lock position, clean the boots on the left and right outer joints and coat the boots with lubricant P/N A 000 989 36 60. There should be no reason to replace the side shafts due to this complaint.
