Drive Shaft:
The drive shaft is the (drive) shaft between the gearbox and the differential (cardan) at the rear. A drive shaft is used in four-wheel drive and rear-wheel drive vehicles and is mounted in the center beneath the car, above the exhaust, from front to rear. The drive shaft is attached to the gearbox and the differential/cardan using coupling disks (rubber discs also known as “Hardy disks” or “Hardyscheibe” through which bolts pass). In the middle of the drive shaft is the support bearing with a universal joint. This support bearing is attached to the underside of the car’s body and allows the shaft to rotate freely without play. The universal joint allows a slight height difference between the gearbox and the cardan (due to the engine block’s mounting on the motor supports).
If the support bearing is mounted incorrectly (too far to the left or right), the drive shaft will make an uneven movement and cause vibrations. This is because the two shafts are no longer aligned, creating an angle. Therefore, it is necessary to reinstall this support bearing as straight as possible in its original position.
