Our aim is to be your primary partner in keeping your BMW in peak condition by providing expertise and parts that match the vehicle's original quality.
How the drivetrain is engineered on the BMW 1 Serie 120 D Xdrive F21
The BMW 1 Serie 120 D Xdrive F21 features a technically sophisticated drivetrain engineered to handle both spirited driving and demanding road conditions. Unlike rear-wheel-drive variants in the 1 Series, the xDrive setup uses a transfer box to direct power to both the front and rear axles. Consequently, the car's layout includes a pair of front drive shafts in addition to the rear shafts. Power is routed from the gearbox via a central propeller shaft to the rear differential, whilst an auxiliary shaft powers the front differential.
Each drive shaft is fitted with an inner and an outer CV joint. The inner CV joint, located closest to the gearbox or differential, accommodates axial movement as the suspension articulates, whilst the outer CV joint at the wheel hub allows the wheels to turn for steering whilst still driving the vehicle forward. This intricate interplay between mechanical components requires every part, from bearings to CV boots, to function flawlessly to prevent energy loss and avoid unnecessary wear on adjacent systems.
Common faults and symptoms
Identifying drivetrain issues on a BMW 1 Serie 120 D Xdrive F21 early can prevent expensive secondary damage. One of the most typical symptoms of a worn outer constant velocity joint is a distinct, rhythmic clicking or knocking noise when cornering sharply at low speeds, such as during parking manoeuvres. If you instead experience vibrations or shuddering through the chassis under acceleration, this frequently points to play within an inner CV joint or an unbalanced prop shaft.
For xDrive owners, it is equally important to pay attention to vibrations felt through the steering wheel, which can signal issues with the front driveshafts. Another critical warning sign is grease splattered around the inside of the wheel rim or wheel arch; this indicates a split CV boot. When the boot fails, lubricant quickly escapes whilst dirt and moisture penetrate, inevitably causing the CV joint to fail shortly afterwards. Taking action at the first sign of wear often means you only need to replace an individual component rather than the complete shaft assembly.
Common parts to replace on the BMW 1 Serie 120 D Xdrive F21
Our comprehensive selection for the BMW 1 Serie 120 D Xdrive F21 includes the most sought-after components for servicing and repairing your vehicle's power delivery. We currently stock four different variants of complete drive shafts, covering the requirements for both the front and rear of this specific model. For repairs where only one section of the shaft is damaged, we provide two types of outer CV joints and a dedicated inner CV joint, offering greater flexibility for your repair work.
Furthermore, we have two different propeller shaft components available, which are essential for resolving driveline vibrations within the four-wheel-drive system. All of our car parts are selected for their durability and exacting tolerances, which is particularly vital on a high-torque performance model like the 120d. By replacing worn components with our quality products, you restore your car's original handling and ensure that the xDrive system delivers torque exactly as intended from the factory, without intrusive noises or mechanical strain.

Frequently Asked Questions about Drivetrain for BMW 1 Serie 120 D Xdrive F21
How do I know if my BMW 120d xDrive needs a new drive shaft?
Common signs include vibrations during acceleration or clicking noises when cornering. You should also inspect the CV boots to ensure they are intact and that no grease has leaked out.
Does the same drive shaft fit both the front left and right side?
On the BMW 1 Serie 120 D Xdrive F21, drive shafts are often side-specific due to the design of the xDrive system. Always select your specific vehicle details to ensure the exact fitting position.
What is the difference between an inner and an outer CV joint?
The outer CV joint is located at the wheel and accommodates steering angles, whereas the inner CV joint connects to the gearbox or differential and accommodates suspension travel.
Can a faulty propeller shaft cause vibrations throughout the car?
Yes, imbalance or worn joints in the propeller shaft of an xDrive model can cause severe vibrations throughout the body, particularly at higher speeds or under load.
Are the CV boot and grease included when I buy a CV joint from you?
Yes, our CV joint kits are supplied complete with a CV boot, grease, clamps and necessary fixings for a professional, hassle-free replacement.
