Audi A3 Sportback 1.4 TSI

The most common signs are vibrations during acceleration or knocking noises when cornering. If you notice shuddering through the chassis that disappears when you lift off the accelerator, it is often the inner joint or the shaft itself that is worn.

It depends on the component. Outer CV joints are often identical on both sides, but drive shafts almost always differ in length between the right and left sides. Always filter by make, model and engine variant to verify the exact fitting position.

Yes, if you catch damage to the CV boot early before dirt and moisture have contaminated the joint, you can save money by replacing just the boot and repacking it with fresh grease. If the joint has already started making noises, the entire CV joint must be replaced.

The outer joint sits at the wheel hub and allows steering movement, whilst the inner joint sits at the gearbox and accommodates the in-and-out plunge of the shaft as the suspension travels. They feature different designs and wear in different ways.

Cars fitted with a DSG automatic transmission often have different spline counts and sometimes different driveshaft lengths compared to manual gearboxes. It is therefore crucial to check your transmission type and select the exact engine and model when ordering.

Replacing a complete drive shaft is usually much faster and fully refreshes the driveline on that side. It eliminates the risk of the remaining joint failing shortly afterwards, ultimately saving on workshop labour costs.
