Welcome to CVJoint24, the international shop of a Swedish driveline specialist supplying the BMW 3 Serie M 340 I Xdrive across the EU. This high-performance model demands premium...
The BMW 3 Serie M 340 I Xdrive represents a fine balance between everyday practicality and exceptional performance. To enable this powerful machine to unleash its full potential, a drivetrain in peak mechanical condition is vital. The drivetrain in an M340i is subjected to substantial torque and heavy loads, particularly during spirited driving when the xDrive system continuously splits power between the front and rear axles. Maintaining and promptly replacing worn components is essential for preserving the vehicle's dynamic handling and safety.
At CVJoint24, we understand the technical demands placed on a modern BMW. We specialise in offering car parts that meet or exceed original equipment specifications, which is particularly vital for a performance model such as the M 340 I. Whether you have noticed vibrations or unusual noises, our goal is to supply the precise components needed to restore your car's original handling precision. By focusing on premium quality and accurate fitment, we help you prevent costly collateral damage to other transmission and driveline assemblies.
The drivetrain on a BMW 3 Serie M 340 I Xdrive is a sophisticated setup built around xDrive, BMW's intelligent all-wheel-drive system. Output from the turbocharged straight-six engine is transmitted via the gearbox to a transfer box. From here, power is distributed via a propeller shaft to the rear axle and via a secondary shaft to the front axle. This system demands millisecond response times and robust mechanical assemblies to cope with the rapid torque shifts that occur while driving.
Each wheel is linked to the differentials by drive shafts. For the BMW 3 Serie M 340 I Xdrive, these shafts are engineered to withstand massive torque loads. Fitted to these shafts are CV joints that allow the wheels to move with suspension travel and steering articulation while continuously transferring power. The inner CV joint, positioned closest to the differential, plays a crucial role in absorbing the axial plunge generated as the suspension compresses and rebounds. The entire system is an intricate assembly of mechanical precision where every component must work flawlessly for the xDrive system to optimise traction.
Despite BMW's high build standards, driveline components suffer from natural wear and tear, especially in a performance car such as the M 340 I. One of the most typical symptoms of driveline trouble is a noticeable shudder or vibration felt through the bodyshell or steering wheel under acceleration. This can frequently be traced back to a worn inner CV joint or an out-of-balance prop shaft. Because the xDrive system is sensitive to rotational differences and driveline drag, even minor wear in the drive shafts can noticeably compromise all-wheel-drive operation.
Another warning sign is unusual knocking or clicking under heavy throttle or on overrun. If a CV boot tears, abrasive road dirt enters while lubricating grease is flung out, accelerating wear on the constant velocity joint until failure occurs. For BMW owners, it is also important to listen out for a whining or thumping noise originating from beneath the centre of the car, which typically points to a failing propeller shaft centre bearing or worn universal joints. Ignoring these warning signs can result in far more expensive damage to the differentials or transfer box, making early diagnosis and replacement of worn parts essential.
To keep your BMW 3 Serie M 340 I Xdrive performing as intended, we have identified the primary driveline components that most frequently require renewal. Our range is tailored to meet the exact requirements of this high-output model. Here are the main product categories we supply:
By choosing model-specific replacement parts from us, you can be confident that all dimensions, load capacities and splines match your vehicle's factory requirements. This precision is especially crucial on M-Sport variants where manufacturing tolerances are tighter and demands on dynamic response are considerably higher than on standard models in the BMW 3 Serie range.

The most common symptoms include vibrations throughout the car under acceleration, clunking or knocking noises when applying throttle, and visible grease leaking from the CV boots. Because the M340i features xDrive, vibrations can also be felt through the steering wheel if the issue lies on the front axle.
No, the M 340 I Xdrive uses specific components engineered for higher power output and torque compared to standard models. Always select your vehicle by make, model and engine variant to ensure the correct fitment.
High-speed vibrations can often be traced to an unbalanced propeller shaft or a worn centre bearing. It can also stem from play in an inner CV joint, which introduces an imbalance into the drivetrain.
Yes, we offer a fitment guarantee when you select your vehicle by make, model and engine variant. This ensures the part is fully guaranteed to fit your specific BMW 3 Serie M 340 I Xdrive.
We dispatch quickly across Europe from our Swedish central warehouse, helping you get your BMW back on the road in no time.
If you catch a damaged boot early and the joint has not started to knock or vibrate, replacing just the CV boot may be enough. However, if grit or road dirt has entered and damaged the joint, replacing the complete drive shaft or CV joint is recommended to ensure long-term reliability.
