Frequently Asked Questions about Audi A4 B9 – Drivetrain & Power Transmission
How do I know if my Audi A4 B9 needs a new drive shaft?
Common symptoms include vibrations under acceleration, clicking noises when cornering, or visible damage and grease leaks from the drive shaft boots.
What is the difference between the inner and outer CV joint on an Audi A4 B9?
The outer CV joint is located near the wheel and typically causes clicking noises when cornering. The inner CV joint sits close to the gearbox and usually causes body vibrations when accelerating.
Does the same propeller shaft fit all Audi A4 B9 Quattro models?
No, the propeller shaft can vary depending on gearbox type and engine variant. Always select your car's make, model and engine to find the correct version.
Why does my Audi A4 B9 vibrate under acceleration?
This is frequently caused by wear in the inner CV joints. When these become worn, play develops, leading to imbalance and vibrations as torque is transferred.
Can I replace just the CV boot if it is split?
Yes, if you catch the damage early before dirt and moisture have ruined the joint, you can replace just the CV boot and repack it with fresh grease.
How do I find the right spare parts for my car?
Select your make, model and engine variant in our search filter, and the range will automatically show only the parts compatible with your specific Audi A4 B9.
Is it difficult to replace a drive shaft on an Audi A4 B9 myself?
It requires the right tools and sound technical knowledge of the suspension. For an experienced DIY mechanic it is entirely feasible, but following the correct tightening torques is essential.
