Outer CV joints for Audi A5 40 TDI
The Audi A5 40 TDI is a car that combines elegant styling with potent performance, with its modern diesel engine delivering substantial torque. This torque places demanding requirements on the vehicle's powertrain, particularly on the outer CV joint. This component forms a crucial link in the chain transferring power from the gearbox to the driven wheels, whilst accommodating steering angles and suspension travel. For any Audi A5 40 TDI owner, ensuring that the drivetrain remains in top condition is essential to preserve the sharp handling and refined ride comfort the model is renowned for.
When choosing an outer CV joint from us, you can be confident of receiving a part tailored precisely to your Audi's technical specifications. We understand that exact tolerances are vital, especially on vehicles featuring sophisticated chassis and drive systems. By focusing on premium materials and precision manufacturing, we supply components that meet or exceed original-equipment performance, ensuring reliable operation and extended service life in demanding European driving conditions.
What does an outer CV joint do on an Audi A5 40 TDI?
The outer CV joint, short for constant velocity joint, transfers rotational force at an unvarying speed regardless of the steering angle. On an Audi A5 40 TDI, this outer joint sits at the very end of the drive shaft, slotted directly into the wheel hub. Unlike the inner CV joint, the outer joint must cope with the substantial steering articulation required when turning. As a result, it is one of the most mechanically stressed components anywhere in the drivetrain.
Its internal design comprises inner and outer bearing races with precision steel balls running in profiled tracks, delivering flexible movement without sacrificing power transfer. For a car driven by the torquey 40 TDI engine, this constant velocity joint endures heavy loads under acceleration, notably when pulling away from a standstill or powering through tight corners. A healthy outer CV joint is therefore vital to prevent power loss and to ensure stability and traction control systems operate correctly, as these depend on smooth mechanical drive to the wheels.
Common signs of wear
The classic symptom of a failing outer CV joint on an Audi A5 40 TDI is a distinct clicking or knocking noise when turning sharply at low speeds, such as during parking manoeuvres. This noise occurs when the steel balls can no longer glide smoothly across their tracks due to excessive wear or degraded lubrication. If the clicking disappears while driving in a straight line but returns on full lock, the outer joint is almost certainly worn out.
Another critical warning sign is a split or torn CV boot. The boot protects the joint from road dirt, water and salt whilst retaining the vital lubricating grease. If grease escapes or contaminants enter, joint failure follows swiftly. You will frequently spot telltale splatters of dark grease across the inner wheel rim or wheel arch. Steering wheel vibrations under hard acceleration can also signal trouble, though these may occasionally stem from other driveline components.
Selecting the correct outer CV joint
Finding the correct replacement outer CV joint for your Audi A5 40 TDI requires careful checking. Audi fitted various joint designs depending on gearbox type, chassis number and whether the car features Quattro all-wheel drive or front-wheel drive. The most important detail to verify is the spline tooth count, both on the stub shaft entering the wheel hub and on the internal spline securing to the drive shaft. Seal diameter and ABS ring specifications can also vary between different model years.
To make identifying the correct part effortless, simply select your Audi A5 40 TDI's exact make, model and engine variant in our shop catalogue. This narrows the selection to parts fully compatible with your vehicle's setup. If multiple options are listed, match the technical specifications, spline counts and dimensions in the product description with your existing component. Getting the right part first time saves both time and workshop labour costs.
Related parts to inspect
We recommend also checking these related categories for your vehicle when replacing an outer CV joint:
When one drivetrain component wears out, neighbouring parts on the same vehicle often show signs of wear as well. Reviewing these dedicated pages for the Audi A5 40 TDI helps you determine whether an issue stems solely from the outer CV joint or involves adjacent transmission components.
This is particularly true for high-torque models where play, vibrations and unusual noises can transmit through connected assemblies. Checking associated categories ensures you do not replace one part while overlooking another that contributes to the same problem.
By inspecting the entire driveline system, you guarantee that your Audi A5 40 TDI continues to run reliably for many miles to come.

Frequently asked questions about outer CV joints for Audi A5 40 TDI
How do I know if my Audi A5 40 TDI needs a new outer CV joint?
The most common sign is a clicking noise when turning at low speeds. You should also check whether the CV boot is split or if there are grease splatters on the inside of the wheel rim.
Can I replace just the outer CV joint, or do I have to replace the whole drive shaft?
On the Audi A5 40 TDI, you can usually replace just the outer CV joint on its own, provided the drive shaft itself is not damaged and does not have worn splines.
Do all outer CV joints fit every Audi A5 model?
No, there are significant differences depending on the engine variant, gearbox and model year. Always select your make, model and engine to find the correct part for your 40 TDI.
What happens if I carry on driving with a damaged CV joint?
In the worst case, the joint can fail completely, meaning power is no longer transmitted to the wheel and the car will break down. It can also cause secondary damage to the wheel hub and gearbox.
Are the CV boot and grease included when I buy an outer CV joint from you?
Yes, our CV joint kits are supplied complete with a CV boot, high-grade grease, clamps and mounting hardware to ensure a proper replacement.
Is it difficult to replace the outer CV joint on an Audi A5 40 TDI myself?
It requires certain tools and mechanical experience, as the wheel hub and brake components often need to be dismantled. We recommend following a workshop manual specific to your model.
