Drivetrain for BMW 4 Serie
The BMW 4 Serie represents a perfect balance between aesthetics and dynamic performance. Maintaining this equilibrium requires a drivetrain capable of handling the torque and forces produced by the engine. The drivetrain is the core of the vehicle's power transmission, consisting of several critical components that work together to deliver power from the gearbox out to the wheels. At CVJoint24, you will find a dedicated range tailored specifically to this model series. We understand the technical demands placed on a modern BMW and therefore supply only parts that meet or exceed original equipment specifications.
Our range extends from the smallest retaining circlip to complete shafts. With 292 matched products for the BMW 4 Serie, we cover most requirements, whether for a standard model or a vehicle with a more powerful engine option. Maintaining the drivetrain is not only essential for operational reliability, but also for preserving the precise steering feel and acceleration that characterise the marque. Choosing the correct components reduces the risk of consequential damage to other areas of the chassis and gearbox.
How the BMW 4 Serie drivetrain is engineered
The drivetrain layout on a BMW 4 Serie varies depending on whether the car is rear-wheel drive (RWD) or equipped with the intelligent xDrive all-wheel drive system. At its foundation, the system relies on longitudinal power transfer via a propeller shaft that directs power to the rear axle. For models with xDrive, a transfer box and a front propeller shaft are added to send power forward to the front axle, where two additional drive shafts take over. This complexity demands that every single component, such as the propeller shaft for BMW 4 Serie, functions flawlessly to prevent vibrations and power loss.
Each drive shaft is fitted with two joints: an inner and an outer constant velocity joint. The inner joint sits closest to the differential or gearbox, accommodating axial movement as the suspension articulates. The outer CV joint sits at the wheel hub, facilitating both steering angles and power delivery. On the BMW 4 Serie, these components are engineered to withstand substantial loads, yet they remain subject to wear from heat, road grime and mechanical stress. Understanding this setup is crucial when diagnosing faults or selecting the right car parts for a repair.
Common faults and symptoms
There are several telltale signs that a component in your BMW 4 Serie drivetrain is beginning to fail. One of the most frequent symptoms is a clicking or knocking noise audible when cornering sharply at low speeds. This typically indicates that an outer CV joint for BMW 4 Serie is worn or has ingested grit through a split boot. If, however, you notice a vibration throughout the car under acceleration, the issue can often be traced to an inner CV joint for BMW 4 Serie or an unbalanced prop shaft.
Another common problem is grease leaking from the CV boots. Once grease escapes, lubrication is lost rapidly, leading to metal-on-metal contact and total failure in short order. You should also pay close attention to vibrations that appear at specific road speeds, which often point to a worn centre bearing on the propeller shaft or lost balance weights on the shaft itself. By acting promptly at the first sign of these symptoms, you can often resolve the issue simply by replacing an individual joint or boot rather than having to install an entire driveshaft assembly.
Common replacement parts for BMW 4 Serie
Depending on driving style and mileage, certain components require replacement more frequently than others. In our BMW 4 Serie range, the breakdown across our most requested categories is as follows:
- Drive shafts (163 items): The most common component to replace in the event of severe wear or impact damage.
- Propeller shafts (60 items): Critical for transmitting power between the front and rear axles, particularly on xDrive models.
- Outer CV joints (41 items): Frequently the first component to wear at the wheel hub due to sharp steering angles and road debris.
- Inner CV joints (28 items): Typically replaced when noticeable vibrations emerge under acceleration.
Opting for a complete drive shaft for BMW 4 Serie is often more cost-effective than rebuilding individual joints, as you receive a fully factory-assembled unit fitted with new boots and fresh grease. This significantly cuts garage installation time and guarantees extended service life for the entire assembly. We also stock specific fitting hardware, including bolts and circlips, essential for a professional job.

Frequently Asked Questions about BMW 4 Series Drivetrain Parts
How do I know if my BMW 4 Series needs a new drive shaft?
The most common signs are vibrations under acceleration, clicking noises when cornering, or visible grease leaking from the CV boots. If you notice an imbalance at higher speeds, this can also indicate a damaged drive shaft.
Does the same drive shaft fit both rear-wheel drive and xDrive models?
No, drive shafts differ between rear-wheel drive and xDrive versions. In addition, xDrive models have front drive shafts, which RWD models do not have. Always select your vehicle's make, model, and engine variant to ensure you receive the correct version.
Can I replace just the CV joint instead of the complete drive shaft?
Yes, if the shaft itself is straight and undamaged, you can often replace just the outer or inner CV joint. This is a cost-effective way to repair the drivetrain if the fault is confined to the joint itself.
What causes propeller shaft vibrations on a BMW 4 Series?
Propeller shaft vibrations are commonly caused by a worn centre bearing, deteriorated flexible coupling discs (guibo), or an unbalanced prop shaft. It is vital to resolve this quickly to prevent damage to the gearbox or differential.
Is it difficult to replace a CV boot yourself?
It requires specific tools and mechanical experience, as the drive shaft usually needs to be removed from the hub. However, it is an essential preventative maintenance task to avoid more costly constant velocity joint repairs.
How many drive shafts does a BMW 4 Series xDrive have?
A BMW 4 Series with xDrive has four drive shafts in total: two at the front and two at the rear, in addition to the propeller shafts that distribute power between the axles.
Why should I choose CVJoint24 for my BMW parts?
