Outer CV joints for Audi Q5 Sportback 40 TDI Quattro
Maintaining the drivetrain on a modern, technologically advanced SUV such as the Audi Q5 Sportback 40 TDI Quattro is crucial for both driving comfort and long-term safety. The outer CV joint sits at the very end of the drive shaft, right next to the wheel, and is the component that allows the wheel to steer freely while the engine's power propels the car forward. Because the 40 TDI Quattro model is equipped with a sophisticated all-wheel-drive system, these components are exposed to specific loads, particularly during heavy acceleration and tight cornering. With us, you will find the right Outer CV joints that match the exact technical demands of your car's drivetrain. We understand the importance of an exact fit to avoid future issues with vibrations or noises in your Audi Q5 Sportback 40 TDI Quattro.
What does the outer CV joint do on the Audi Q5 Sportback 40 TDI Quattro?
The outer CV joint, or constant velocity joint, is primarily tasked with transferring torque smoothly from the gearbox and drive shaft to the front wheels at a constant rotational speed. This must happen regardless of the steering angle or the movements of the suspension. On an Audi Q5 Sportback 40 TDI Quattro, this is especially critical because the Quattro system actively distributes torque between the axles to optimise traction on varying road surfaces. The outer joint must handle tight angles at full steering lock while dealing with the high torque output from the TDI engine. To work optimally, the joint is protected by a CV boot filled with specialist grease. This boot is vital as it retains the lubrication while sealing out moisture, road salt and dirt that would otherwise quickly ruin the precision-ground bearing surfaces inside the joint.
Common signs of wear
There are several clear warning signs indicating that an outer CV joint on your Audi is nearing the end of its service life. The most classic symptom is a rhythmic clicking or knocking noise heard when turning sharply, such as during a U-turn or whilst parking. The frequency of the noise typically increases with vehicle speed. Another common sign is vibrations felt through the steering wheel or the chassis under acceleration, which often suggests the joint has developed play or that the lubrication has broken down. If a visual inspection reveals grease splattered over the inside of the wheel rim or around the wheel arch, this is a sure sign that the CV boot has split. If this is not sorted straight away, dirt and water will enter the joint, leading to complete mechanical failure where the car eventually loses drive entirely.
How to choose the right outer CV joint
Selecting the right spare part for an Audi Q5 Sportback 40 TDI Quattro requires precision, as variations can occur depending on the production month, chassis number and specific equipment packages. The most reliable way to find the correct component is to filter by your car's make, model and engine variant in our store. This quickly brings up the parts technically verified for your car's exact specifications. When choosing an outer constant velocity joint, it is essential to check the spline count – the number of teeth on both the internal and external splines of the joint – and confirm compatibility with the vehicle's ABS setup. By purchasing from a dedicated driveline specialist, you eliminate the risk of ordering the wrong part and receive a component that meets or exceeds original specifications. We help you choose the right part from the start so your repair is smooth and lasting.
Related parts to inspect
It is also worth checking these exact pages for the same vehicle when working on the outer CV joint:
When one drivetrain component shows signs of wear, nearby parts on the same car often warrant an inspection as well. Comparing these exact pages for the Audi Q5 Sportback 40 TDI Quattro makes it easier to determine whether the fault lies strictly with the outer CV joint or with an adjacent section of the power transmission system.
This is especially relevant on vehicles where vibrations, play and unusual noises can transfer symptoms across several parts in the same driveline. A quick check of related categories reduces the risk of replacing the right type of part while overlooking a neighbouring component that contributes to the very same problem.
When replacing an outer CV joint, it is the ideal time to inspect surrounding drivetrain components to prevent future problems. A worn CV joint can sometimes be the consequence of other imbalances or damage. We recommend checking the following components:
- Drive shafts for Audi Q5 Sportback 40 TDI Quattro – Check whether the shaft itself shows signs of imbalance, corrosion or bending.
- Inner CV joint – Inspect for any play or leakage where the shaft enters the gearbox.
- Wheel bearing – As the hub is often dismantled during the job, it is easy to check whether the bearing spins smoothly without roughness or noise.
- ABS sensor and ring – Clean and inspect the sensor to ensure it sends clean signals to the vehicle's safety systems.

Frequently asked questions about outer CV joints for Audi Q5 Sportback 40 TDI Quattro
How do I know if the outer CV joint is failing on my Audi Q5 Sportback?
The most common sign is a clicking noise when cornering. If the noise stops when driving in a straight line but returns on lock, it is almost always the outer CV joint that is worn.
Can I continue driving with a split CV boot?
No, this is not recommended. A split boot allows grease to leak out and dirt to enter, which ruins the CV joint in very short order. Replace the boot immediately to save the joint.
Do all CV joints from the Audi Q5 also fit the Sportback model?
Not necessarily. The Sportback 40 TDI Quattro can feature specific dimensions and spline counts depending on engine output and drivetrain setup. Always select your car's make, model and engine to verify fitment.
What is included when I buy an outer CV joint from you?
Our kits are complete and typically include the CV joint itself, a new boot, specialist grease, circlips, clamps and, where required, a new centre bolt or nut.
Why does the car vibrate under acceleration if the CV joint is worn?
Vibrations under acceleration are often caused by internal play in the joint, which creates an imbalance when torque is applied. This is a clear indicator that the joint is severely worn.
Is it difficult to replace the outer CV joint on an Audi Q5 Sportback 40 TDI Quattro?
It requires some mechanical experience and the correct tools to detach the hub and drive shaft. For an experienced DIY mechanic or garage, the job normally takes between 1 and 2 hours per side.
