Audi A8 4.2 Quattro drivetrain
The Audi A8 4.2 Quattro represents an engineering pinnacle where effortless power meets refined precision. The drivetrain in this luxury saloon is built to handle the high torque output of the potent V8 engine, delivering legendary Quattro all-wheel drive with unwavering stability. Maintaining these components is vital for preserving the car's distinctive driving dynamics and safety. As a driveline specialist, we understand the exacting demands placed on an Audi A8 4.2 Quattro, where every part of the power transmission system must interact seamlessly to prevent unnecessary wear on the gearbox and differentials. Choosing the right spare parts ensures your car's performance remains at its absolute peak for years to come.
When it comes to the drivetrain of an Audi A8, it is not merely about turning the wheels, but about preserving the silent, vibration-free ride that defines the model. Worn parts can quickly degrade cabin refinement and, in worst-case scenarios, lead to costly mechanical breakdowns. We supply car parts rigorously tested to withstand the loads imposed by all-wheel drive, especially under hard acceleration and challenging driving conditions across European roads. Our focus is on providing components that match or exceed original specifications, ensuring your Audi remains the high-performance thoroughbred it was when leaving the factory.
How the Audi A8 4.2 Quattro drivetrain is designed
The drivetrain layout on the Audi A8 4.2 Quattro is both sophisticated and robust, engineered to deliver maximum traction in every scenario. The setup centres on a longitudinally mounted engine ahead of the front axle, paired with an advanced automatic gearbox incorporating an integrated Torsen differential. This centre differential actively distributes torque between the front and rear axles depending on available grip. Power reaches the rear wheels via a central propeller shaft for the Audi A8 4.2 Quattro, while the front wheels are driven by short, heavy-duty drive shafts running straight from the transmission casing. This symmetrical layout is the foundation of the car's balanced handling.
Each wheel connects via drive shafts fitted with both inner and outer CV joints. These constant velocity joints are vital, allowing the wheels to travel smoothly with the suspension while enabling the front wheels to steer. On an Audi A8 4.2 Quattro, these components are engineered to endure substantial torque, but they rely strictly on intact CV boots to retain lubricating grease and seal out abrasive dirt. The technical sophistication of the Quattro system means tolerances are exceptionally tight, making exact-fit replacement parts an absolute necessity to prevent driveline imbalance and unwanted noises.
Common faults and symptoms
Several distinct symptoms indicate that driveline components are wearing out on your Audi A8. One classic warning sign is a rhythmic clicking or snapping sound when cornering sharply at low speeds. This almost invariably points to a worn outer CV joint on your Audi A8 4.2 Quattro, frequently caused by a split CV boot that has allowed grit and road grime to contaminate the bearing surfaces. Conversely, if you feel shuddering or vibration through the floorpan or seats under brisk acceleration, the issue can often be traced to a failing inner CV joint on the Audi A8 4.2 Quattro or a worn prop shaft centre bearing.
Another common issue on this model affects the braking and active safety electronics. If the ABS warning light illuminates on the dashboard, or if you feel the ABS pulsing unexpectedly under light braking on dry tarmac, an ABS ring on the Audi A8 4.2 Quattro has often cracked or suffered heavy corrosion. Because the Audi A8 relies on advanced electronic stability programmes, an intact ABS reluctor ring is essential for the system to operate correctly. Ignoring these early warnings can cause persistent vibrations that ruin gearbox oil seals or lead to total joint failure, leaving you stranded at the roadside.
Common replacement parts for the Audi A8 4.2 Quattro
For the Audi A8 4.2 Quattro, we at CVJoint24 have developed a range covering the most critical driveline maintenance requirements. Our warehouse currently stocks several variants of driveshafts, catering to the various axle positions and technical revisions introduced across the model's production run. We also supply 3 types of outer CV joints and multiple inner CV joints, giving you the flexibility to replace a worn joint instead of buying a complete shaft assembly if the shaft itself remains in sound condition. This provides a cost-effective and technically sound repair.
In addition to drive shafts and joints, we stock 1 dedicated propeller shaft that comes fully balanced and ready to install—essential for eliminating high-speed driveline resonance. To keep the vehicle's braking and electronic safety systems operating without error, we also supply 2 distinct types of ABS rings. With these specialised components in stock, we make it simple to find exactly what you need for your Audi A8 4.2 Quattro. Every part in our inventory is carefully selected for durability, meeting the uncompromising standards expected of a luxury performance vehicle.

Frequently Asked Questions about Drivetrain Parts for Audi A8 4.2 Quattro
How do I know if a CV joint is failing on my Audi A8 4.2 Quattro?
The most common signs are a clicking noise on full steering lock (outer CV joint) or vibrations through the car under acceleration (inner CV joint). If you spot grease on the inside of the wheel rim, it could be due to a split CV boot, which quickly leads to premature wear of the joint.
Can I replace just the ABS ring, or do I need to replace the entire CV joint?
On the Audi A8 4.2 Quattro, it is often possible to replace just the ABS ring if it has cracked or rusted through, provided the CV joint itself is otherwise in good condition. We supply standalone ABS rings to make the repair more cost-effective.
Why is it important to select the correct make, model and engine when searching?
The Audi A8 4.2 Quattro was manufactured with different technical specifications depending on model year and chassis number. By selecting your car's exact make, model and engine, our catalogue ensures you receive parts with the correct spline count and length, activating our fitment guarantee.
What causes propeller shaft vibrations on an Audi A8?
Propeller shaft vibrations are often caused by imbalance, worn universal joints or a failing centre bearing. Because the prop shaft rotates at high speed, even minimal play or imbalance can cause noticeable vibrations in the cabin.
Are mounting fittings included when I buy a CV joint from you?
Yes, when you purchase a CV joint kit for your Audi A8 from us, it normally includes everything required for the replacement, such as a CV boot, grease, clips and, where applicable, a new centre bolt or circlip.
How quickly can I receive my parts for my Audi A8?
We aim to dispatch orders quickly on weekdays for prompt delivery across Europe. As a Swedish driveline specialist, we keep most parts for the Audi A8 4.2 Quattro in our own warehouse to minimise your waiting time.
