Inner CV joints for BMW 6 Serie 640 D Xdrive F12
The BMW 6 Serie 640 D Xdrive F12 is a car that combines exquisite luxury with powerful performance. With its six-cylinder diesel engine and intelligent xDrive all-wheel drive system, heavy demands are placed on every component in the drivetrain. The inner CV joint plays a central role in transferring massive torque from the gearbox out to the wheels. Because the F12 chassis is engineered for both comfort and dynamics, the CV joints must maintain exceptional quality to eliminate unwanted vibrations and ensure seamless power delivery.
When owning a high-performance vehicle like a BMW 640d, it is essential not to compromise on the quality of your spare parts. A substandard inner CV joint can wear out rapidly under the heavy strains generated by the xDrive system, especially during hard acceleration. At CVJoint24, we specialise in these critical driveline components so that you can rely on your car's dependability in every driving situation.
What does the inner CV joint do on a BMW 6 Serie 640 D Xdrive F12?
The inner CV joint, frequently a tripod joint or plunge joint, is mounted closest to the gearbox or differential. Its primary purpose is to allow the drive shaft to plunge linearly (axial movement) as the car's suspension travels up and down. Unlike the outer constant velocity joint, which mainly accommodates steering angles, the inner joint focuses on maintaining smooth power transmission regardless of the road surface or vehicle load.
For a BMW 6 Serie 640 D Xdrive F12, this is especially critical. The xDrive system distributes power continuously between the front and rear axles, meaning the inner joints on the front drive shafts work hard to handle both high torque and the angular changes caused by active driving. A properly functioning inner CV joint minimises friction and heat build-up, in turn extending the service life of the complete drive shaft assembly.
Common signs of wear
Wear on an inner CV joint often presents differently from an outer joint. The most typical symptom is vibration felt throughout the car during acceleration. These vibrations tend to disappear when you lift off the accelerator and coast. Because the BMW 640d produces substantial torque, these vibrations become very pronounced when the joint begins to fail, particularly at speeds between 70 and 100 km/h.
Another common sign is unusual noise, such as a dull clunking or clicking sound under load. If the CV boot protecting the joint has split, grease escapes and road dirt enters, leading to rapid degradation of the internal bearing surfaces. If you spot grease splatters underneath the car or near the gearbox, inspect your inner CV joints immediately to prevent a catastrophic failure that could damage other drivetrain components.
How to choose the correct inner CV joint
Selecting the correct inner CV joint for a BMW 6 Serie 640 D Xdrive F12 requires precision. Variations exist depending on production month, gearbox type, and whether the part is for the front or rear axle. It is crucial to verify the spline count on both the side entering the gearbox and the side mating with the drive shaft, as well as checking the sealing surface diameters.
To make the process as straightforward and reliable as possible, select your BMW's make, model, and engine variant in our store selector. This filters out the components engineered specifically for your car's exact driveline configuration. This is particularly vital for xDrive models, where driveshafts and joints differ considerably from rear-wheel-drive 6 Series variants. With our technical expertise, you will receive car parts that meet BMW's exacting standards for fit and durability.
Related components to inspect
We recommend also checking 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 car often require attention too. By comparing these exact pages for the BMW 6 Serie 640 D Xdrive F12, you can more easily determine whether an issue lies purely with the inner CV joint or with an adjacent section of the drivetrain.
This is especially true for models where vibrations, play, and noises can travel between several driveline components. Checking related categories reduces the risk of replacing one correct part while overlooking an adjacent component that causes the same symptom.

Frequently asked questions about inner CV joints for BMW 6 Serie 640 D Xdrive F12
What are the most common symptoms of a failing inner CV joint on a BMW 640d xDrive?
The most common symptom is noticeable vibration through the car body under acceleration, which typically subsides when you ease off the throttle. Unlike outer CV joints, they rarely produce clicking noises when cornering.
Can I replace just the inner CV joint, or do I need to replace the entire drive shaft?
On the BMW 6 Serie F12, it is often possible to replace only the inner CV joint if the drive shaft itself is otherwise undamaged. This provides a cost-effective way to restore proper drivetrain function.
Why do inner CV joints wear faster on xDrive models?
All-wheel drive directs power through all four wheels, which places additional load on the front inner CV joints. Furthermore, the high torque produced by the 640d engine subjects the joint to significant stress.
Are the CV boot and grease included when I purchase an inner CV joint from you?
Yes, our inner CV joints are supplied as complete kits containing the joint itself, a model-specific CV boot, high-quality grease, and the required fitting components such as clamps.
How do I ensure I select the correct inner CV joint for my BMW F12?
The most reliable method is to select your car's make, model, and engine in our search tool. We then match your vehicle's exact technical specifications against our range to guarantee the correct fit.
What happens if I continue driving with a damaged inner CV joint?
Prolonged vibrations can damage the gearbox output seals and bearings, as well as cause premature wear to suspension components. In the worst case, the joint can fail completely, resulting in a total loss of drive.
