General description of drive shafts (Audi A4 B5)

1. The torque from the differential to the front wheels is transmitted via two drive shafts, made of a solid log or pipe, depending on the model. Both shafts have splined ends connected to the wheel hub, secured with a large bolt. The inner joints of the shafts are attached to the gearbox flanges with six bolts.

2. Constant velocity joints (CV joints) are installed at both ends of the shaft to ensure the movement of the wheels when the vehicle is moving. Petrol models with manual transmissions have both ball-type joints with cages. Diesel models and models with automatic transmissions are equipped with shafts with outer ball-type joints and inner ones with tripod-type roller joints.

3. Rubber or plastic covers are attached to the hinges with clamps. Inside the covers there is grease, which is also stuffed into the hinge. The cover protects the hinge from dirt penetration.
