Inner CV joints for BMW 1 Serie M 135 I Xdrive F20
Finding the right inner CV joint for a BMW 1 Serie M 135 I Xdrive F20 demands precision and technical knowledge. Renowned for its potent straight-six engine and intelligent all-wheel-drive system, this specific model places rigorous demands on every component throughout the drivetrain. Mounted directly beside the gearbox or differential, the inner CV joint plays a crucial role in transferring substantial engine torque to the wheels. Because the M135i xDrive delivers serious performance, replacement parts must meet the highest quality standards to withstand the intense loads generated under hard acceleration and dynamic cornering. At CVJoint24, we specialise in these precise driveline components so you can choose replacement car parts for your BMW 1 Serie M 135 I Xdrive F20 with complete confidence.
What does the inner CV joint do on a BMW 1 Serie M 135 I Xdrive F20?
The inner CV joint on a BMW 1 Serie M 135 I Xdrive F20 serves a unique, technically demanding purpose compared with the outer joint. While the outer joint handles steering angles at the front wheels, the inner constant velocity joint accommodates the axial plunge and changes in drive shaft length as the suspension travels over bumps and road undulations. In an all-wheel-drive car such as the xDrive F20 series, these joints must operate seamlessly to ensure smooth, vibration-free power distribution between the front and rear axles. If an inner joint begins to fail, it upsets drivetrain balance, degrading overall performance and compromising BMW’s signature refined drive. This component relies on precise lubrication with correct grease and an intact CV boot to deliver a long, dependable service life.
Common signs of wear
How do you tell when it is time to replace the inner CV joint on your BMW? One classic symptom of inner joint wear is shuddering or vibration that occurs specifically under acceleration. Unlike wheel imbalance—which is typically felt through the steering wheel at particular road speeds regardless of throttle—vibrations from a failing inner joint resonate through the car body and usually fade the moment you lift off the accelerator. You might also notice a clicking or clunking sound when engaging drive or reverse, pointing to excessive play within the joint mechanism. Another frequent sign is a torn CV joint boot leaking grease. Starved of lubrication, the internal metal surfaces rapidly wear down from friction and grit ingress, ultimately risking total joint failure that can lead to costly damage to the differential or gearbox casing.
How to choose the correct inner CV joint
Selecting the correct inner CV joint for your BMW 1 Serie M 135 I Xdrive F20 can seem tricky given the subtle engineering variations across the BMW range. Variations exist across production years and specific driveline setups, with xDrive models often requiring distinct spline counts, shaft diameters, and differential flange interfaces. To ensure you receive a part with an exact fit, we recommend selecting your car's make, model, and engine variant on cvjoint24.com. This filters our catalogue to parts engineered for your vehicle's exact chassis and mechanical specifications. Comparing original equipment manufacturer (OEM) part numbers against our detailed technical specifications guarantees a hassle-free installation and durability that meets BMW's stringent performance standards.
Related components to inspect
When working on your inner CV joint, it is best practice to inspect these related pages for the same vehicle:
When one drivetrain component shows signs of wear, adjoining parts often warrant close inspection too. By checking these exact pages for the BMW 1 Serie M 135 I Xdrive F20, you can more easily determine whether a fault lies strictly within the inner CV joint or elsewhere along the power transmission assembly.
This is particularly critical on performance models where vibrations, mechanical play, and knocking sounds can travel across connected driveline parts. A quick look at related categories ensures you do not replace one part while overlooking a worn companion component affecting the same symptoms.

Frequently asked questions about inner CV joints for BMW 1 Serie M 135 I Xdrive F20
How do I know if the inner CV joint has failed on my BMW M135i?
The most common symptom is body vibration under acceleration that disappears as soon as you ease off the throttle. You may also hear clicking noises under load.
Can I replace just the CV boot if the joint seems undamaged?
Yes, if you catch damage to the CV boot early and the joint is still clean and well lubricated, renewing the boot alone may be enough to prevent future failure.
Is there a difference between inner CV joints for xDrive and rear-wheel drive?
Yes, dimensions and splines often differ between four-wheel-drive and rear-wheel-drive models. Always select your car's make, model and engine to find the correct version.
Why does my BMW vibrate under acceleration but not at a steady cruising speed?
This is a classic symptom of a worn inner CV joint. When the joint is loaded during acceleration, play in the tripod mechanism creates an imbalance, leading to vibrations.
Are fitting accessories such as grease and clamps included?
Yes, our inner CV joints are supplied as complete kits with high-grade grease, a CV boot and the necessary clamps for a proper installation.
How quickly will my new CV joint be delivered?
We aim for fast dispatch on all in-stock parts so you can get your BMW 1 Serie M 135 I Xdrive F20 back on the road as quickly as possible.
