Technicians should particularly check whether the rubber bellows on the joints are worn, damaged or leaking. Because any splash water that gets in washes out the special grease, this then allows dirt particles to enter the joint.

Vehicle owners may complain of a howling noise in the drivetrain in the area of the rear axle between 80 km/h and 110 km/h (50 mph to 70 mph). The cause could be resonance in the drivetrain stimulated by the meshing of the gear set in the rear axle differential (drive pinion/ring gear).
The mission of ZF Aftermarket’s Technical Training department is to provide in-depth knowledge of automotive technology to industry students, technicians and professionals.
