Drive shafts — general information (Mercedes-Benz S-Class W140)

The car is driven by transmitting torque from the gearbox to the wheels via two drive shafts of different lengths. The right shaft consists of two parts. The dust boots of the inner joints are made of rubber, and the outer ones are made of thermoplastic (thermoplastic is more resistant to external influences).

Each shaft consists of three main parts: the inner tripod joint, the shaft itself, and the outer constant velocity joint (CV joint). The inner joint of the left shaft is fixed inside the box with a locking ring. The inner joint of the right shaft is installed in a specially designed socket of the intermediate shaft.

The intermediate shaft, in turn, enters the bearing located inside the box and is fixed with a bracket attached to the rear side of the cylinder block. The outer joints of both shafts (CV joints) end in splined shafts that enter the splined hubs of the drive wheels. The shafts are fixed in the hubs with nuts.
