Inner CV joints for Audi A5 Sportback 40 Tfsi Gtron
Maintaining the drivetrain of an Audi A5 Sportback 40 Tfsi Gtron demands premium-quality components. The inner CV joint is a critical link in the vehicle's power transmission, located closest to the gearbox. For a car equipped with advanced Gtron technology, it is especially important that all mechanical parts work together smoothly without friction or imbalance. At CVJoint24, we understand the specific engineering requirements of this model and supply only parts that meet or exceed original equipment specifications.
Replacing a worn joint in good time prevents consequential damage to adjacent drivetrain components, such as the gearbox output shafts or the drive shaft itself. Our range is carefully selected to fit your specific Audi A5 Sportback 40 Tfsi Gtron, giving you total confidence that each component is optimised for the vehicle's torque and weight distribution.
What does an inner CV joint do on the Audi A5 Sportback 40 Tfsi Gtron?
The inner CV joint on your Audi A5 Sportback 40 Tfsi Gtron performs a different task compared to the outer joint. Whilst the outer joint accommodates steering angles, the inner joint handles the axial movement that occurs as the suspension travels up and down. It operates as a telescopic link, allowing the drive shaft to change length during driving without losing positive engagement with the gearbox.
For an Audi A5 Sportback, this ensures engine power is transferred smoothly to the wheels regardless of road conditions or load. If this component begins to fail, the car's overall driving dynamics are compromised. A properly functioning inner CV joint minimises internal friction and maintains the quiet, refined ride expected of an Audi, especially during motorway cruising and hard acceleration.
Common symptoms of wear
There are clear warning signs when an inner constant velocity joint starts to deteriorate on an Audi A5 Sportback 40 Tfsi Gtron. The most common symptom is noticeable vibration through the body shell or the driver's seat during acceleration. Unlike an outer CV joint, which typically clicks on tight turns, an inner joint produces vibrations that intensify under engine load.
You may also notice a clunking noise when lifting off the throttle or changing gear, which indicates excessive play within the joint's internal mechanism. Another clear sign is grease leakage around the gearbox, frequently caused by a split CV boot that has allowed lubricant to escape. Once the grease is lost, the joint wears rapidly due to heat build-up and dirt ingress. Ignoring these symptoms can lead to total joint failure and a complete loss of drive.
Choosing the right inner CV joint
When selecting a replacement inner CV joint for your car, precision is vital. Audi frequently uses different joint designs depending on the gearbox type and engine specification, even within the same model year. For the Audi A5 Sportback 40 Tfsi Gtron, it is essential to check the spline count on both the drive shaft side and the gearbox side, as well as the outer diameter of the joint housing.
The most reliable way to find the correct part is to select your car's exact make, model and engine variant in our catalogue. This filters the components that match your vehicle's technical specifications. We also recommend choosing a complete joint kit that includes a new CV boot, grease and mounting hardware, as these should always be replaced together to ensure maximum service life and reliability from your new spare parts.
Related parts to inspect
We recommend checking these exact pages for the same vehicle when working on the inner CV joint:
When a drivetrain component shows signs of wear, neighbouring parts on the same car often require inspection too. Comparing these exact pages for the Audi A5 Sportback 40 Tfsi Gtron makes it easier to determine whether an issue lies with the inner CV joint itself or another related part of the driveline.
This is particularly relevant for models where vibrations, play and mechanical noises can travel between several drivetrain components. A quick check of related categories reduces the risk of replacing one correct part while overlooking an adjacent component that contributes to the same fault.

Frequently asked questions about inner CV joints for Audi A5 Sportback 40 Tfsi Gtron
How do I know if the inner CV joint on my Audi A5 Sportback 40 Tfsi Gtron is faulty?
The most common symptoms are body vibrations under acceleration and a clunking or knocking noise when accelerating or engine braking. Vibrations are often more noticeable at higher speeds.
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. This is often a much more cost-effective solution than replacing the complete shaft.
Why does my Audi A5 Sportback vibrate under acceleration?
Vibrations under acceleration are often caused by wear in the inner CV joints, as they endure the highest load when engine torque is transmitted to the wheels.
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 with a model-specific CV boot, premium-grade grease and the necessary mounting hardware for a proper replacement.
How do I find the exact inner CV joint for my 40 Tfsi Gtron?
Select your vehicle's make, model and engine variant in our search filter. This is the most reliable way to find parts with the correct spline count and dimensions for your specific car.
What is the difference between an inner and an outer CV joint?
The outer CV joint sits at the wheel hub and handles steering angles, while the inner joint sits by the gearbox and accommodates suspension movement by allowing the drive shaft to plunge axially.
