Inner CV joints for Audi A4
The Audi A4 is renowned for its sophisticated chassis engineering and precise handling, but maintaining this performance requires every part of the drivetrain to operate flawlessly. The inner CV joint plays a crucial role here. At CVJoint24, you will find one of the most comprehensive ranges of inner CV joints for the Audi A4 on the market. With over 200 matched products, we cover everything from the early B5 models right through to the latest generations. Each component is thoroughly selected to meet or exceed original specifications, providing you with a long-term solution to issues with vibrations or noises.
Owning an Audi A4 often entails high demands for reliability. Because the model is available in a wide variety of configurations – from economical TDI engines to powerful petrol units and the legendary Quattro system – the demands on drivetrain components vary considerably. We possess deep technical knowledge of these variations and supply parts specifically engineered for the differing torque outputs and loads within your car's drivetrain. By choosing the right part from a specialist, you ensure that your car continues to deliver the driving dynamics it was built for.
What does the inner CV joint do on an Audi A4?
The inner CV joint on an Audi A4 is fitted closest to the gearbox and serves a different function from the outer joint. Whilst the outer joint primarily manages steering angles, the main duty of the inner joint is to absorb the changes in length that occur as the car's suspension moves up and down. This is commonly referred to as a "plunging joint". Without this flexibility, the drive shaft would snap as soon as the vehicle traversed a bump or during heavy acceleration when the body squats or lifts.
On the Audi A4, the inner joint is frequently a tripod design or a ball-type construction, depending on the gearbox type and engine torque. It transmits power from the gearbox output flange to the drive shaft with minimal friction. As the Audi A4 is often designed with a longitudinally mounted engine, the positioning of the inner joints is critical to minimise angular errors and vibrations. A properly functioning inner constant velocity joint is therefore vital for smooth power delivery without energy loss, which would otherwise adversely affect both fuel economy and ride comfort if the component is worn.
Common signs of wear
Wear in an inner CV joint on an Audi A4 typically presents different symptoms compared to a failing outer joint. The most classic symptom is vibration or juddering through the vehicle's body under acceleration. These vibrations are often felt most distinctly at speeds between 50 and 90 km/h and usually vanish the moment you release the accelerator pedal. This happens because the internal rollers or balls within the joint have created small indentations in the housing, preventing the shaft from centring itself properly under load.
Another common sign is noise, frequently described as a dull thudding or clicking sound when driving over road imperfections or under sudden throttle application. It is also essential to inspect the CV boot regularly. If the boot splits, the specialised CV joint grease leaks out while dirt and water ingress. This drastically accelerates wear and can cause total failure in a very short time. If you notice grease splattered on the vehicle's underside or around the gearbox near the drive shaft, it is high time to check your inner CV joint before more extensive and costly damage occurs.
How to choose the correct inner CV joint
Choosing the correct inner CV joint for an Audi A4 can be challenging, as there are several technical specifications to bear in mind. Knowing the model year and engine is not always sufficient, as Audi frequently utilised different suppliers and technical configurations within the same production run. The most critical factors to verify are the number of splines (teeth) on the shaft, the diameter of the flange mating with the gearbox, and whether the joint is a tripod or ball-type design. Furthermore, parts often differ depending on whether the car has a manual or automatic gearbox (such as Multitronic or S-tronic).
To make the selection straightforward and dependable, we always recommend filtering by your car's make, model and engine variant. This isolates the parts that are technically compatible with your specific car configuration. If you are carrying out the job yourself, it is also good practice to count the splines on the old part before fitting to ensure total accuracy. Remember that an inner CV joint on a Quattro model can differ between the front and rear axles, so take care to check the fitting position in the product description. With our extensive inventory and specialist expertise, we help you avoid incorrect orders and ensure your Audi A4 receives the exact part it requires.
Related parts to check
It is also worth checking these exact pages for the same vehicle when working on the inner CV joint:
When a drivetrain component displays wear, adjacent components on the same car often require inspection as well. Comparing these exact pages for the Audi A4 makes it easier to determine whether the issue stems purely from the inner CV joint or another neighbouring section of the power transmission system.
This is particularly relevant on models where vibrations, play and unusual noises can shift symptoms across multiple components within the same drivetrain. A quick check of related categories reduces the risk of replacing the correct type of part while overlooking an adjacent component that contributes to the very same fault.

Frequently Asked Questions about Inner CV Joints for Audi A4 - Quality Drivetrain Parts
What are the most common symptoms of a failing inner CV joint on an Audi A4?
The most common signs are body vibrations under acceleration, often noticeable between 50 and 90 km/h. Unlike outer CV joints, clicking noises rarely occur when turning; instead, the issue typically presents as an imbalance under load.
Can I replace just the inner CV joint, or do I need to replace the entire drive shaft?
On most Audi A4 models, you can easily replace just the inner CV joint. This is often a more cost-effective solution if the rest of the drive shaft and the outer joint remain in good condition.
How do I know if my Audi A4 uses a tripod joint or a ball-type CV joint?
This usually depends on your gearbox type and engine variant. The most reliable way to find the correct version is to select your car's exact make, model and engine on our website, where we list detailed technical specifications for each configuration.
Does the same inner CV joint fit both front-wheel-drive and all-wheel-drive Audi A4 models?
No, they can vary. On Quattro models, inner joints are fitted both front and rear, and these are rarely identical. Always check the product description to confirm whether the component is intended for the front or rear axle.
Are the CV boot and grease included when I buy an inner CV joint from you?
Yes, our inner CV joints are supplied as complete kits containing the joint itself, a vehicle-specific CV boot, high-grade CV joint grease, and all necessary clips and fitting hardware.
Why does my Audi A4 only vibrate when accelerating?
This is a classic symptom of a worn inner CV joint. Under acceleration, torque loads the joint; if pitting or wear grooves have formed inside the housing, this creates an imbalance that resonates as vibration throughout the vehicle.
Is it difficult to replace an inner CV joint on an Audi A4 yourself?
It requires moderate mechanical experience and the correct tools, as the drive shaft must be unbolted from the gearbox output flange. Audi A4 models frequently use XZN (spline) bolts for this mounting, so ensure you have the appropriate sockets ready before starting the job.
