The inner CV joint is a critical component in your Audi A5 45 Tfsi Mild Hybrid Quattro. This specific model combines modern mild-hybrid technology with the legendary Quattro all-wheel-drive system, placing high demands on the drivetrain components. An inner CV joint for this car must efficiently transmit torque while accommodating the angular changes caused by suspension movements. At CVJoint24, you will find parts engineered precisely to your vehicle's specifications, ensuring long service life and optimal performance. We understand how essential it is to maintain the premium driving dynamics of an Audi A5, which is why we only provide components that meet or exceed original equipment standards.
On an Audi A5 45 Tfsi Mild Hybrid Quattro, the inner CV joint is installed closest to the gearbox or differential. Its primary function is to allow the drive shaft to move up and down in step with the suspension while transferring rotational power from the engine to the wheels. Unlike the outer CV joint, which primarily accommodates steering angles, the inner constant velocity joint is designed to allow axial plunge. This is particularly vital on an all-wheel-drive vehicle like the Quattro, where torque distribution between the axles changes constantly. A smooth-running inner joint minimises friction and energy loss, which is essential to the overall efficiency of a mild-hybrid drivetrain.
Wear on an inner CV joint often presents differently from issues with an outer joint. The most frequent symptom is vibration felt throughout the cabin under acceleration, particularly at higher speeds or under heavy loads. If you notice the steering wheel or seats vibrating when accelerating, which then vanishes as soon as you release the throttle, this is a classic indicator of a worn inner joint. Another symptom is a dull clunking or knocking noise under load. It is also vital to inspect the CV boot; if it splits, grease leaks out and dirt gets in, rapidly ruining the internal bearing surfaces.
Selecting the right replacement part for a technologically sophisticated vehicle like the Audi A5 45 Tfsi Mild Hybrid Quattro can seem daunting. Differences can occur depending on the chassis number or specific production date. To ensure complete compatibility, always check the spline tooth count on both the inner and outer sections of the joint, alongside its overall dimensions. The simplest and most reliable method is to select your vehicle by make, model and engine variant on our website. This filters our catalogue down to verified components for your exact car, eliminating guesswork and ensuring a precise fit first time.
We recommend also checking these exact pages for the same vehicle when working on the inner CV joint:
When a drivetrain part shows signs of wear, neighbouring components on the car often require attention too. Comparing these exact pages for the Audi A5 45 Tfsi Mild Hybrid Quattro makes it easier to determine whether the issue lies specifically with the inner CV joint or with an adjacent section of the driveline.
This is especially important on models where vibrations, play and unwanted noises can be transferred between interconnected drivetrain parts. A quick check across related categories reduces the risk of replacing one component while overlooking an adjacent worn part that contributes to the same problem.
Carrying out a thorough inspection ensures your Audi stays reliable and prevents premature wear on new components caused by imbalances elsewhere in the driveline.

The most common signs are pronounced vibrations through the car's body during acceleration, which often ease off when you lift off the throttle, as well as dull thumping noises from the drivetrain.
It is not recommended. A damaged inner CV joint can cause imbalances that damage the gearbox or, in the worst case, cause the drive shaft to come loose, leaving the car undriveable.
It requires sound mechanical knowledge and the right tools, as the drive shaft often needs to be removed completely. For an experienced DIY mechanic it is manageable, but time-consuming.
Yes, our inner CV joints are supplied as complete kits with a CV boot, grease, clips, and any mounting hardware required for a proper replacement.
Vibrations under acceleration are a typical symptom of a worn inner constant velocity joint that has developed play in its bearing surfaces, creating imbalance as torque is transferred.
This varies depending on the vehicle's design. On many Audi models they are identical, but always select your car's make, model and engine to confirm the exact fitment for your vehicle.
