Inner CV joints for Audi A4 S4 Quattro
The Audi A4 S4 Quattro represents a fine balance between everyday practicality and high-performance sportiness, placing demanding requirements on the vehicle's mechanical parts. The inner CV joint is one of the most vital links in this setup, transmitting power straight from the engine's torque via the gearbox. On a car equipped with the sophisticated Quattro system, drivetrain precision is paramount to distribute power seamlessly between the front and rear axles. At CVJoint24, we supply inner CV joints engineered specifically to withstand the higher loads experienced by an S4 model compared to standard versions. By choosing the right spare parts, you preserve your car's sharp acceleration and stability whilst minimising the risk of costly future repairs. Our range covers the exacting requirements necessary when maintaining these high-performance vehicles.
What does an inner CV joint do on the Audi A4 S4 Quattro?
The inner CV joint on an Audi A4 S4 Quattro is typically a tripod joint or a heavy-duty plunge joint. Its primary purpose is to allow the drive shaft to plunge in and out axially, which is essential as the car's suspension articulates over road imperfections. Without this flexibility, the driveshaft would either be forced against the gearbox or pulled apart during substantial suspension travel. On an S4 Quattro, with its stiffer chassis setup and controlled suspension travel, the joint is subjected to rapid and intense load shifts. The inner joint also acts as a damper, isolating vibrations from the engine and gearbox to prevent them from reaching the wheels and entering the passenger cabin. Understanding the role of this component explains why replacement part quality is crucial for your overall driving experience and long-term vehicle durability.
Common signs of wear
Symptoms of a worn inner CV joint on an Audi A4 S4 Quattro can be subtle initially, but they deteriorate quickly under load. The most noticeable sign is a distinct vibration or shudder through the car body during acceleration, particularly between 60 and 100 km/h. Unlike wheel imbalance, these vibrations typically vanish as soon as you lift off the accelerator. Another telltale sign is a clunking noise when shifting between drive and reverse, indicating excessive play inside the constant velocity joint. It is also vital to inspect the CV boots regularly. A split boot allows the lubricating grease to escape whilst letting in road grit and moisture. This creates an abrasive paste that rapidly ruins the hardened contact surfaces inside the joint. If you notice grease splattered across the inner wheel rim or gearbox casing, inspect the joint without delay.
Choosing the correct inner CV joint
Selecting the exact inner CV joint for your Audi A4 S4 Quattro demands precision. Knowing the model year alone is often insufficient, as Audi frequently implemented running technical changes during a production run. You need to check the spline count on the shaft entering the joint as well as the splines connecting to the gearbox flange. Additionally, the outer diameter of the joint housing is a critical measurement to ensure clearance in the compact front-end assembly. We have made finding the correct part straightforward: simply select your car's make, model and engine variant in our store. Our vehicle selector filters the exact components matched to your specific vehicle configuration. This ensures that the spare part you order fits correctly on installation, saving you valuable time and frustration in the garage.
Related components to inspect
Please feel free to check these matching pages for the same vehicle when working on the inner CV joint:
When a drivetrain component develops wear, neighbouring parts on the same car often require attention too. Comparing these exact pages for your Audi A4 S4 Quattro makes it straightforward to establish whether an issue stems solely from the inner CV joint or from an adjoining area of the power transmission.
This is especially important on performance models where vibrations, play and unusual noises can transfer across multiple drivetrain components. Checking related categories helps avoid replacing one worn part whilst overlooking another that contributes to the very same symptom.

When overhauling the drivetrain on an Audi A4 S4 Quattro, it is good engineering practice to review the entire power transmission assembly. If the inner joint is worn out, the outer CV joint has likely endured comparable mileage and stress. In many instances, renewing the complete drive shaft assembly proves more cost-effective and saves workshop time. On Quattro-equipped vehicles, checking the propeller shaft is also essential, as prop shaft centre bearing vibration can easily be mistaken for CV joint trouble. Do not forget to inspect the ABS rings, as corrosion or cracking can trigger faults in the braking system.

Frequently asked questions about inner CV joints for Audi A4 S4 Quattro
How do I know if the inner CV joint is worn on my Audi A4 S4 Quattro?
Vibrations or shuddering through the body shell under acceleration, which disappear when you lift off the throttle, are the most common signs of a worn inner CV joint.
Can I replace just the boot if the joint still feels fine?
Yes, if you catch a split boot early and the joint has not started to make noises or vibrate, replacing the CV boot and applying fresh grease can be enough.
Are inner CV joints different between manual and automatic gearboxes on the S4 Quattro?
Yes, there can be differences in the splines, overall length and mounting flanges depending on which gearbox your Audi is fitted with.
Why does my Audi A4 S4 Quattro vibrate under acceleration?
This is often caused by wear or play in the inner CV joint, which introduces an imbalance into the drive shaft as engine torque is transferred.
Are grease and fitting accessories included when I buy an inner CV joint?
Yes, our inner CV joints are supplied as complete kits with a CV boot, specialist grease, clips and any circlips or snap rings needed for installation.
