Drive shafts for BMW 3 Serie 320 SI E90

Drive shafts for BMW 3 Serie 320 SI E90

The BMW 3 Serie 320 SI E90 is an exceptional car, developed as an exclusive homologation special for WTCC touring car racing. As a result, the demands placed on its drivetrain components are significantly higher than on standard models. The drive shaft is a vital element of the car's power delivery, responsible for transferring torque from the differential out to the rear wheels with minimal loss. Because the 320 SI features a unique high-revving engine and a specific chassis setup, choosing a drive shaft engineered precisely for this variant of the E90 platform is critical. At CVJoint24, you will find components that meet or exceed original equipment specifications, ensuring your BMW preserves its distinctive handling characteristics and reliability. Investing in the right quality is key to protecting the long-term value and performance of this rare car.

What does a drive shaft do on a BMW 3 Serie 320 SI E90?

On a rear-wheel-drive car like the BMW 3 Serie 320 SI E90, the primary role of the drive shaft is to transfer mechanical torque from the final drive to the wheel hubs. It consists of a robust central bar fitted with two precision-engineered CV joints: an inner constant velocity joint at the differential and an outer joint at the wheel hub. These joints allow the shaft to alter its operating angle smoothly as the suspension moves through its complete travel, all whilst transmitting rotational power evenly. For a car with sporting pedigree and stiffer suspension like the 320 SI, it is vital that these components are flawlessly balanced and manufactured from high-strength steel. This minimises unwanted vibrations and ensures power reaches the tarmac instantly, whether driving on the road or the track.

Common signs of wear

Several clear symptoms indicate that a drive shaft on your BMW is nearing the end of its service life. One of the most typical signs is vibration felt throughout the bodyshell, particularly under heavy acceleration or across specific speed bands. This frequently points to wear within the inner CV joint where internal tolerances have widened. Another frequent indicator is a rhythmic clicking or knocking noise under load, typically originating from the outer joint. You should also carry out regular visual inspections of the CV boots. If a boot splits, the joint is exposed to road dirt, grit and moisture, whilst the essential lubricating grease escapes. Ignoring these warning signs can result in complete failure, potentially causing severe damage to surrounding suspension components and the differential. Early detection prevents expensive repair bills.

How to choose the correct drive shaft

Selecting the right drive shaft for a BMW 3 Serie 320 SI E90 requires precision, as this model features unique technical details that set it apart from standard editions. The most reliable way to ensure an exact fit is to select your car's make, model and engine variant in our store. It is crucial to verify the overall compressed length of the driveshaft and count the splines at both ends before starting the installation. As the 320 SI was built in a limited production run, specific parts may differ from a regular 320i. We also recommend confirming whether your vehicle requires a specific ABS reluctor ring setup, as an incorrect signal can disrupt the car's dynamic stability control. By sourcing from a specialist like CVJoint24, you gain access to accurate technical data and parts guaranteed to match your car's precise specifications.

Related parts to check

Please also check these exact pages for the same vehicle when working on the drive shaft:

When one drivetrain component shows signs of wear, neighbouring parts on the vehicle often require attention as well. By checking these exact pages for the BMW 3 Serie 320 SI E90, it becomes straightforward to identify whether an issue lies with the drive shaft itself or another related section of the drivetrain.

This is especially important on performance models where vibrations, play and noises can easily travel between multiple driveline parts. A quick inspection of related categories prevents replacing one component whilst overlooking a neighbouring part that causes the same symptom.

• Propeller shafts for BMW 3 Serie 320 SI E90
• Propeller shaft centre bearings for BMW 3 Serie 320 SI E90
• ABS rings for BMW 3 Serie 320 SI E90

Inspecting the condition of the propeller shaft and the prop shaft centre bearing's rubber mounting is essential, as an imbalance here can transfer through the driveline and damage a replacement drive shaft. Furthermore, the ABS ring is a recognised weak point on BMW models of this era; corrosion underneath can cause the ring to expand and damage the wheel speed sensor. Checking these parts during your repair work helps avoid future breakdowns and saves on workshop labour costs over time.
