Audi A3 1.8 Tfsi Quattro

Common signs include severe vibrations under acceleration or unusual noises from the wheel arches. If you notice the car shaking under load but settling down when you lift off the accelerator, this often points to a worn drive shaft.

The outer CV joint sits closest to the wheel and accommodates steering angles; it typically clicks when cornering when worn or broken. The inner CV joint sits against the gearbox or differential and accommodates suspension travel; it usually causes vibrations during acceleration.

No, the front and rear drive shafts have different lengths and specifications. In addition, they often differ between the left and right side. Always check your car's model year, gearbox and exact engine code to select the correct fitting position.

This is most often caused by internal play in one of the CV joints or an imbalance in the propeller shaft. Because the Quattro system distributes power to all four wheels, vibrations can feel more pronounced than on a two-wheel-drive car.

We recommend inspecting the CV boots at every service or wheel swap. A split boot quickly leads to constant velocity joint failure due to the ingress of dirt and moisture.

It is often possible to replace just the CV joint if the shaft itself is undamaged. However, if multiple joints are worn or the shaft is heavily corroded, replacing the complete drive shaft is often more cost-effective and dependable.
