Inner CV joints for Audi A5 Sportback 40 TDI Quattro
Maintaining the drivetrain on a high-performance vehicle like the Audi A5 Sportback 40 TDI Quattro demands components of the highest standard. The inner CV joint plays a central role in your car's power transfer, especially alongside the Quattro all-wheel-drive system which places stringent demands on durability and precision. This specific model variant requires parts capable of handling the high torque generated by the 40 TDI engine, whilst preserving the refined comfort and stability expected of an Audi. We supply inner constant velocity joints engineered to meet or exceed original equipment specifications, ensuring long service life and dependable operation in all driving conditions.
What does the inner CV joint do on the Audi A5 Sportback 40 TDI Quattro?
Fitted closest to the gearbox or differential, the inner CV joint serves a distinct purpose compared to the outer joint. Whilst the outer joint primarily accommodates steering angles, the main task of the inner CV joint is to allow the drive shaft to plunge in and out longitudinally. This travel is vital because the distance between the gearbox and the wheel hub changes constantly as the car's suspension articulates over road surfaces. On an Audi A5 Sportback 40 TDI Quattro, this movement is crucial for delivering smooth power to all four wheels without stressing the drivetrain. Without a properly functioning inner joint, suspension movement would cause severe mechanical strain on both the gearbox and suspension.
Common signs of wear
Wear in an inner CV joint usually reveals itself differently to that of an outer joint. The most frequent symptom is a shudder or vibration felt throughout the cabin under acceleration, particularly at higher speeds or under heavy engine loads. In contrast to an outer joint, which typically clicks when cornering, a worn inner joint produces a deeper, duller noise or shaking that appears to originate from the centre of the car or the floorpan. If you notice unusual vibrations when accelerating in your Audi A5 Sportback 40 TDI Quattro, or spot grease leaking from the CV boot near the gearbox, it is crucial to inspect the inner joint promptly before consequential damage spreads to other drivetrain components.
How to choose the correct inner CV joint
Finding the correct inner CV joint for your Audi A5 Sportback 40 TDI Quattro can be intricate, as specifications often vary depending on the production date and exact factory equipment. Key details to verify include the number of internal and external splines (teeth) as well as the outer joint diameter. To ensure a seamless process, we recommend filtering by make, model and engine variant in our store selector to view components matched to your car. Sourcing the right part first time prevents unexpected fitment issues and guarantees exact compatibility, giving you complete confidence during installation and long-term reliability.
Related components to check
It is also advisable to inspect these related parts for your car when servicing the inner CV joint:
When a drivetrain part develops wear, adjacent components often undergo similar stress. Reviewing these relevant pages for the Audi A5 Sportback 40 TDI Quattro makes it straightforward to confirm whether an issue stems purely from the inner CV joint or another connecting section of the drivetrain.
This is especially important on four-wheel-drive models, where vibrations, play and unwanted noises can readily travel along the driveline. A quick check of related categories helps you avoid replacing one worn part whilst overlooking another connected component that contributes to the very same problem.

Frequently asked questions about inner CV joints for Audi A5 Sportback 40 TDI Quattro
What are the most common symptoms of a failing inner CV joint on an Audi A5 Sportback?
The most common signs are vibrations throughout the car under acceleration and load. Unlike outer CV joints that click when cornering, inner joints typically cause shuddering or shaking that can be felt through the bodywork.
Can I replace just the inner CV joint, or do I need to replace the entire drive shaft?
You can certainly replace just the inner CV joint if the rest of the drive shaft is in good condition. It is often a very cost-effective way to cure vibrations.
How do I make sure the CV joint fits my 40 TDI Quattro?
The most reliable method is to select your car's exact make, model and engine variant in our vehicle selector. This matches your vehicle's specific details with the correct spare parts in our catalogue.
Are a CV boot and grease included when I buy an inner CV joint from you?
Yes, our inner CV joints are supplied as complete kits including the required CV boot, high-grade grease and fitting hardware such as circlips.
Why does the inner CV joint wear out on an Audi A5?
Wear is frequently caused by a split or damaged CV boot allowing grease to escape and dirt to enter, or simply through natural wear and tear after many kilometres handling high torque.
Is there a difference between inner CV joints for Quattro and front-wheel-drive models?
Yes, Quattro models often feature specific dimensions and mountings to handle the power distribution of all-wheel drive, so choosing the correct variant is essential.
