Here you will find our selection of outer CV joints for the Audi A4 45 TFSI quattro (from 2018). This section is dedicated exclusively to all-wheel-drive saloon models, allowing you to...
The Audi A4 45 Tfsi Quattro is a car that combines high performance with an advanced all-wheel-drive system, placing unique demands on the vehicle's mechanical components. The outer CV joint on this model is subjected to severe stresses, especially during hard acceleration and tight turns where the torque from the powerful 45 TFSI engine must be distributed efficiently. Because the engine delivers substantial torque, components of the highest quality are essential to avoid premature wear. With us, you will find outer CV joints specifically engineered to handle the forces generated by the Quattro system in every driving situation. Selecting the correct part is crucial for maintaining the car's renowned handling characteristics and high safety levels. We are drivetrain specialists and understand the precise technical requirements of your Audi, allowing us to supply parts that match original specifications perfectly.
The outer CV joint on your Audi A4 45 Tfsi Quattro plays a critical role in the car's complex power delivery. Its primary job is to transfer rotational energy from the drive shaft to the wheel hub, whilst allowing the wheel to move freely up and down with the suspension and turn with the steering. On a Quattro model, this is particularly intricate as drive is directed to all four wheels, placing extreme demands on the joint's articulation angles and strength under load. The outer joint is typically a Rzeppa constant velocity joint, which ensures a uniform rotational speed at the driven wheel regardless of the steering angle. Without a fully functioning outer CV joint, the car could not be steered safely under power, and engine torque would not reach the road with the precision that Audi drivers expect. It is a precision component that requires proper lubrication and protection to perform reliably over time.
There are several clear symptoms indicating that the outer CV joint on your Audi is wearing out and requires replacement. The most typical symptom is a clicking or knocking noise clearly audible when cornering, particularly at lower speeds and under acceleration. If the noise disappears once you straighten the steering wheel and drive in a straight line, it is a very strong sign that the outer joint is to blame. Another symptom is steering-wheel vibration whilst driving, pointing to imbalance or internal damage within the joint. You should also inspect the CV boot visually on a regular basis. If the boot is split or has come loose, the essential grease leaks out whilst dirt and water penetrate. This forms an abrasive paste that quickly destroys the joint's internal bearing surfaces. If you spot grease splattered on the inside of the wheel rim or around the wheel arch, it is time to act before total failure occurs, which could leave the car stranded.
Selecting the correct outer CV joint for an Audi A4 45 Tfsi Quattro demands precision and care. Knowing the car model alone is not always enough, as factors such as gearbox type, chassis number, and the exact build date can affect the part's technical dimensions. Crucially, you must check the spline count (the teeth) on both the inner stub that connects to the driveshaft and the outer stub that fits into the wheel hub. Furthermore, if the ABS ring is integrated into the joint, it must feature the exact tooth count required for the vehicle's safety and stability control systems to function correctly. We strongly advise using our vehicle selector by choosing your car's make, model and engine on this page. This is by far the most reliable way to filter for parts with a guaranteed fit for your specific Audi variant. By choosing a joint with the right specifications, you ensure straightforward installation and trouble-free performance for many thousands of kilometres.

When a drivetrain component exhibits wear, surrounding components on the vehicle often require inspection as well. Comparing these exact pages for the Audi A4 45 Tfsi Quattro makes it easier to determine whether the issue lies in the outer CV joint itself or in another adjacent section of the drivetrain.
This is particularly relevant on models where vibrations, play, and noises can transfer between multiple drivetrain components. 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.
Replacing the outer CV joint is an ideal opportunity to inspect other parts of the drivetrain to ensure your vehicle remains in top condition. A worn outer joint can sometimes indicate that the entire drive shaft has been subjected to abnormal stress or that a boot has been torn for an extended period. Also inspect the inner CV joint, which commonly causes vibrations throughout the entire car under acceleration if damaged. For Quattro owners, checking the propeller shaft and its centre bearing is equally important, as both are vital to the four-wheel-drive system.

The most common symptom is a clicking or knocking noise when turning, especially under acceleration. Vibrations in the steering wheel and grease splattered across the wheel rim from a split CV boot are also clear warning signs.
No, CV joints vary significantly depending on the engine variant and whether the car has Quattro four-wheel drive or front-wheel drive. Always select your exact make, model and engine to find the correct part tailored to the 45 Tfsi model.
Our outer CV joints are supplied as complete kits. This means you receive the joint itself, a model-specific CV boot, high-grade CV joint grease, circlips, and the necessary clamps for correct installation.
Yes, if you catch a split boot early before road dirt has penetrated and damaged the bearing surfaces, replacing the boot and repacking it with fresh grease may be sufficient. However, if noises are already audible, the entire joint must be replaced.
In the worst-case scenario, a damaged CV joint can shear completely, resulting in a total loss of drive and leaving you stranded. Furthermore, a defective joint can cause secondary damage to wheel bearings and drive shafts due to imbalance and vibrations.
Our fitment guarantee means that when you select your vehicle's make, model and engine variant and order the recommended part, we guarantee it will fit your car. If anything should not match against expectations, we will help you find the correct part right away.
