Inner CV joints for Audi 100 S4 Turbo Quattro
The Audi 100 S4 Turbo Quattro is an iconic performance car that combines potent turbocharging with the legendary Quattro all-wheel-drive system. This combination places exceptionally high demands on the vehicle's drivetrain, and particularly on the inner CV joint. The inner CV joint is fitted closest to the gearbox or differential and is responsible for transferring torque to the drive shafts regardless of suspension movement. For a car with the power potential of the S4 Turbo Quattro, it is vital that these components are in top condition to maintain both performance and safety on the road.
When maintaining an Audi 100 S4 Turbo Quattro, you should never compromise on quality. A worn inner constant velocity joint can cause secondary damage to other parts of the transmission system, which quickly becomes costly. At CVJoint24, we understand the technical nuances of Audi's classic performance drivetrains and supply parts that meet or exceed original equipment specifications. Choosing the correct spare parts ensures your car continues to deliver the driving experience it was built for.
What does the inner CV joint do on the Audi 100 S4 Turbo Quattro?
The inner CV joint, often referred to as the inboard joint or tripod joint depending on the design, has a specific function distinct from the outer joint. While the outer joint manages large steering angles, the primary job of the inner joint is to accommodate axial movement. As the wheels travel up and down over road imperfections, the effective distance between the gearbox and the wheel hub changes. The inner CV joint allows the drive shaft to extend and plunge smoothly without interrupting power transfer or creating tension in the system.
On an Audi 100 S4 Turbo Quattro, these joints work under constant load, particularly under hard acceleration where the Quattro system distributes power between the front and rear axles. The inner joint must cope with both the immense torque from the five-cylinder turbo engine and the vibrations inherent to a high-performance drivetrain. A properly functioning inner joint minimises friction and ensures power reaches the road as efficiently as possible, which is fundamental to the car's driving dynamics.
Common symptoms of wear
Wear in an inner CV joint usually presents differently from wear in an outer joint. The most typical symptom of a failing inner CV joint on an Audi 100 S4 Turbo Quattro is vibration felt through the car body or seat during acceleration. These vibrations tend to disappear when you lift off the accelerator or coast. If the vibrations intensify at specific road speeds or under heavy load, it is a clear sign that the joint's internal raceways are worn or the lubrication has degraded.
Another common sign is abnormal noise, often described as a dull thud or clunking sound when shifting between forward and reverse, or under sudden throttle application. It is equally important to inspect the CV boots regularly. If a boot splits, the grease leaks out and dirt gets in, rapidly ruining the precision-machined surfaces inside the joint. For a performance vehicle like the S4, acting quickly on these symptoms prevents vibrations from damaging the differential or gearbox output bearings.
How to choose the correct inner CV joint
Selecting the right inner CV joint for an Audi 100 S4 Turbo Quattro can be tricky, as variations exist depending on the model year and exact chassis number. The most crucial check is the spline count on both the shaft side and the gearbox flange side, as well as the outer diameter of the joint housing. Because the S4 features an uprated drivetrain compared to standard Audi 100 models, parts from smaller engine variants do not fit. You need components built to withstand the turbo model's higher torque output.
The most reliable way to find the correct component is to select your car's make, model and engine in our selector. This filters out incompatible options and presents parts tailored to your specific vehicle configuration. Always check the product description to ensure all necessary fitting hardware—such as fresh high-pressure grease, a durable CV boot, and circlips—is included in the kit. Replacing the complete joint rather than attempting to patch up a worn unit is almost always the most cost-effective and dependable long-term solution.
Related components to inspect
We recommend also checking these exact pages for the same vehicle when working on the inner CV joint:
When one drivetrain component shows signs of wear, nearby parts on the same car often require attention as well. By checking these exact pages for the Audi 100 S4 Turbo Quattro, it becomes much easier to determine whether an issue lies with the inner CV joint itself or an adjacent part of the drivetrain.
This is particularly relevant on models where vibrations, play and unwanted noises can transfer symptoms across several driveline components. A quick inspection of related categories reduces the risk of replacing one part whilst overlooking an adjacent component that causes the same fault.

- Drive shafts for Audi 100 S4 Turbo Quattro
- Outer CV joints for Audi 100 S4 Turbo Quattro
- ABS rings for Audi 100 S4 Turbo Quattro
Replacing worn components at the same time reduces driveline imbalance and ensures completely vibration-free power delivery. The ABS reluctor ring in particular is an item that is frequently overlooked, yet it is straightforward to replace whenever the drive shaft is already removed.

Frequently Asked Questions about inner CV joints for Audi 100 S4 Turbo Quattro
What are the most common symptoms of a failing inner CV joint on an Audi 100 S4?
The most common signs are vibrations through the body of the car under acceleration, typically noticeable at speeds between 50 and 90 km/h. Unlike outer CV joints that click when cornering, inner joints cause shuddering and shaking that stops as soon as you lift off the accelerator.
Can I use an inner CV joint from a standard Audi 100 on my S4 Turbo Quattro?
No, usually not. The S4 Turbo Quattro features a heavy-duty drivetrain engineered to handle higher torque. It is vital to check the spline count and dimensions carefully, or select your exact model and engine on our website to find the correct part.
Are the boot and grease included when I buy an inner CV joint from you?
Yes, our inner CV joint kits are supplied complete, containing the joint itself, a tailored CV boot, high-quality grease, circlips, and new bolts where required to ensure a correct and secure installation.
How often should I inspect the CV boots on my Quattro?
We recommend a visual inspection at every oil service or at least once a year. On a four-wheel-drive car such as the Audi 100 S4 there are more boots to keep an eye on, and spotting a split early can save you the cost of replacing the entire joint.
Why does my car only vibrate under acceleration but not when coasting?
This is a classic symptom of wear in the inner CV joint's internal tracks. Under load, the internal components are forced against the worn surfaces, generating imbalance and vibrations. When coasting, the load is removed and the shaking subsides.
Is it difficult to replace the inner CV joint on an Audi 100 S4 myself?
It requires good mechanical knowledge and the right tools, as the drive shaft must be removed and the joint is typically bolted to the gearbox flange. For an experienced DIY mechanic it is entirely doable, but correct torque settings and absolute cleanliness are essential.
