Inner CV joints for BMW 6 Serie 640 I Xdrive F12
Maintaining the drivetrain on a high-performance car like the BMW 6 Serie 640 I Xdrive F12 is crucial for both driving pleasure and safety. The inner CV joint plays a pivotal role in this system by transferring power from the gearbox or differential out to the wheels while accommodating suspension movements. For the F12 model, which seamlessly blends luxury with sporting performance, components must withstand the significant torque delivered by the 640i engine. At CVJoint24, you will find specially selected car parts that meet the rigorous demands of your BMW 6 Serie 640 I Xdrive F12. We focus on providing the correct part straight away, saving you time and avoiding unnecessary visits to the garage. Every component is meticulously chosen to match the precise technical specifications of this model generation.
What does an inner CV joint do on a BMW 6 Serie 640 I Xdrive F12?
The inner CV joint on a BMW 6 Serie 640 I Xdrive F12 serves a specific purpose that differs slightly from that of the outer joint. While the outer constant velocity joint primarily manages steering angles, the inner joint is engineered to allow axial plunge. This movement is necessary because the distance between the differential and the wheel hub changes as the car moves up and down over road imperfections. On an xDrive model, this setup is particularly sophisticated as power is distributed to all four wheels. A fully functional inner constant velocity joint ensures that power transfer remains smooth and seamless, which is fundamental to the poise and stability BMW all-wheel drive is renowned for. Ignoring a worn joint can cause consequential damage to other drivetrain components, leading to costly repairs down the line.
Common signs of wear
There are several clear warning signs indicating that the inner CV joint on your BMW is beginning to fail. Unlike an outer CV joint, which typically clicks on full steering lock, a failing inner joint usually produces noticeable vibrations during acceleration. These vibrations can often be felt throughout the cabin and chassis, and they tend to subside when lifting off the throttle. Another common symptom is a dull clunking noise under load or when driving over road bumps. It is also essential to inspect the CV boot; if it is split or torn, grease will leak out and road dirt will penetrate, quickly destroying the internal mechanism. If you experience shuddering in your BMW 640i xDrive, it is high time to inspect the condition of your drivetrain before complete component failure occurs.
How to choose the correct inner CV joint
Selecting the right inner CV joint for a BMW 6 Serie 640 I Xdrive F12 requires precision. Because BMW uses different suppliers and specifications depending on the exact build date and equipment options, knowing the model name alone is not always enough. You must consider the number of splines on both the inside and outside of the joint, as well as its physical dimensions. The most reliable way to find the correct fit is to filter by your car's exact make, model and engine variant in our store. This narrows the selection to car parts that are guaranteed to match your vehicle. We always advise comparing the new component to the original part before beginning installation to ensure a smooth repair and long-lasting reliability. A precise fit is the key to a quiet, vibration-free ride.
Related components to check
Be sure to also check these exact pages for the same vehicle when working on the inner CV joint:
When one drivetrain component shows signs of wear, related parts on the same car often require inspection too. By checking these exact pages for the BMW 6 Serie 640 I Xdrive F12, it becomes much easier to determine whether an issue lies purely with the inner CV joint or another neighbouring section of the driveline.
This is particularly relevant on models where vibrations, play and unusual noises can transfer symptoms across several parts in the same assembly. A quick check of related categories reduces the risk of replacing the right type of part while overlooking an adjacent component that causes the same fault.

Frequently asked questions about inner CV joints for BMW 6 Series 640i xDrive F12
How do I know whether it is the inner or outer CV joint that is faulty on my BMW?
A worn outer CV joint typically produces a clicking noise when turning sharply. In contrast, a worn inner CV joint causes vibrations through the bodywork during acceleration, which usually disappear as soon as you lift off the accelerator.
Can I replace just the boot if the inner CV joint appears undamaged?
Yes, if you catch a split CV boot early before dirt has entered or the grease has leaked out completely, replacing the boot and repacking it with fresh grease can often save the joint.
Does the same inner CV joint fit all models in the BMW 6 Series range?
No, specifications differ depending on the engine, gearbox and whether the car has xDrive all-wheel drive or rear-wheel drive. Always select your vehicle's make, model and engine variant to ensure you get the correct part.
Why does my BMW 640i xDrive vibrate under acceleration?
Vibration under acceleration is a classic symptom of a worn inner CV joint. It occurs because the joint can no longer keep the drive shaft properly centred under load.
Are grease and clips included when I buy an inner CV joint from you?
Yes, our CV joint kits are normally supplied complete with the required specialist grease, CV boot and fitting clips to ensure a straightforward, correct installation.
How quickly can I have my new CV joint delivered?
We aim to dispatch all orders as quickly as possible. When you order an in-stock item, it is dispatched promptly from our warehouse to keep your car's downtime to a minimum.
