Inner CV joints for Audi A5 40 TDI
Maintaining the drivetrain on an Audi A5 40 TDI requires components capable of handling the torque and precision demanded by modern Audi engineering. The inner CV joint is mounted closest to the gearbox and plays a critical role in the car's power delivery by managing the angular changes caused by suspension movement. For an Audi A5 40 TDI, choosing the right quality is especially vital, as the characteristic torque of the diesel engine places considerable strain on the internal mechanism of the CV joints. At CVJoint24, we specialise in these exact driveline parts so that you can feel confident your car will retain its original driving characteristics and high level of comfort. Our range is carefully selected from leading manufacturers to meet the strict demands on durability, materials and precise fitment required for German premium cars.
What does an inner CV joint do on an Audi A5 40 TDI?
The primary task of the inner CV joint is to transmit power from the gearbox to the drive shaft whilst allowing the shaft to plunge inwards and outwards (axially) as the suspension moves up and down. Unlike the outer CV joint, which primarily handles large steering angles at the wheels, the inner constant velocity joint focuses on absorbing the longitudinal movements that occur when driving over uneven road surfaces. On an Audi A5 40 TDI, this system is exceptionally sophisticated in order to minimise NVH (Noise, Vibration, Harshness). If this component does not work optimally, you lose the smooth, seamless power delivery that characterises a modern Audi, negatively affecting both fuel efficiency and the overall driving experience. The inner joint is often a tripod or ball-type design depending on the specific gearbox configuration in your 40 TDI, which makes choosing the correct spare part even more essential.
Common signs of wear
Wear on an inner CV joint often presents as subtle yet irritating symptoms that gradually worsen over time. The most common sign by far is vibration felt through the car's bodywork or seats under acceleration, particularly at speeds between 70 and 110 km/h. Unlike wheel imbalance, which is typically felt through the steering wheel, vibrations from an inner joint correlate directly with engine load. You may also notice a clicking or clunking noise when switching between forward and reverse gears, indicating play within the joint's internal bearing raceways. Another critical sign is a split or loose CV boot; if the specialised grease leaks out and road grime or moisture gets in, the hardened contact surfaces are rapidly destroyed. For an Audi A5 40 TDI owner, it is sensible to inspect these drive shaft boots at every service to prevent complete failure.
How to choose the correct inner CV joint
Finding the correct inner CV joint for your Audi A5 40 TDI can present a technical challenge, as Audi often uses different suppliers and specifications depending on the production month and equipment trim. To guarantee a perfect installation, you should check the number of splines (teeth) on the shaft, the outer diameter of the joint, and the way it secures to the gearbox. The safest and easiest way to navigate this is to select your car by make, model and engine here on cvjoint24.com. We have invested substantial resources into building a database that maps your car's exact technical specifications. This eliminates the risk of ordering the wrong part and ensures you receive a component ready to fit directly without modifications, saving valuable time in the garage.
Related parts to inspect
It is also worth checking these matching pages for the same vehicle when working on the inner CV joint:
When one drivetrain component shows signs of wear, it is common for surrounding parts on the same car to require an inspection as well. Comparing these exact pages for the Audi A5 40 TDI makes it easier to determine whether an issue lies with the inner CV joint or another neighbouring part of the driveline.
This is particularly relevant on models where vibrations, play and noises can shift symptoms across several parts in the same drivetrain. A quick check of related categories reduces the risk of replacing the correct component type while overlooking an adjacent part that contributes to the very same problem.
By reviewing the complete drivetrain at the same time, you ensure your Audi remains dependable and avoid future vibration issues stemming from worn components left behind.

Frequently asked questions about inner CV joints for Audi A5 40 TDI
How do I know if the inner CV joint is failing on my Audi A5 40 TDI?
The most common symptom is body vibration during acceleration, particularly at higher speeds. Unlike wheel imbalance, these vibrations are usually felt more through the seat than through the steering wheel.
Can I replace just the inner CV joint, or does the entire shaft have to be replaced?
On an Audi A5 40 TDI, it is often possible to replace just the inner CV joint. However, if the drive shaft itself or the outer joint is also worn, replacing the complete drive shaft may be more cost-effective.
Are the boot and grease included when I buy an inner CV joint?
Yes, our inner CV joints are supplied as complete kits including the CV boot, high-quality grease, clamps and any bolts or circlips required for installation.
Why does my Audi A5 40 TDI vibrate under acceleration?
Vibration under acceleration is a classic sign that the inner constant velocity joint has developed play or that the grease has leaked out, creating an imbalance in power transmission under load.
Do all inner CV joints fit the Audi A5?
No, there are variations depending on the engine option and gearbox. For the Audi A5 40 TDI, it is important to check the spline count and diameter, which is easiest by selecting your exact model and engine in our vehicle selector.
How quickly will the spare part be delivered?
We dispatch our stocked parts quickly across the EU so that you can get your Audi A5 40 TDI back on the road as promptly as possible.
