Drivetrain for Mercedes Benz CLA
The Mercedes Benz CLA is a model that combines sporting design with advanced engineering. To maintain the driving pleasure and precision that define the marque, a drivetrain in top condition is essential. The drivetrain is responsible for transferring engine power to the wheels, and in a car like the CLA—often featuring front-wheel drive or all-wheel drive (4MATIC)—these components are subjected to substantial stresses. At CVJoint24, we specialise in these exact parts to give you the best conditions for trouble-free ownership. By choosing the right spare parts, you ensure not only your car's reliability, but also its resale value and on-road performance.
How the drivetrain is engineered on the Mercedes Benz CLA
The Mercedes Benz CLA is built on a transverse-engine platform, which means the drive shafts differ in length between the right and left sides. Power travels from the gearbox via the inner CV joint, through the drive shaft, and out to the outer CV joint mounted in the wheel hub. For models equipped with 4MATIC, a propeller shaft and rear driveshafts are also included. This compact yet robust setup demands high-precision components to minimise vibrations and maximise power transfer. Every component in the system, from the smallest circlips to the solid shafts, plays a crucial role in how the car behaves under acceleration and cornering. Understanding this layout is key to identifying the correct spare part once wear begins to show.
Common faults and symptoms
There are several clear signs that the drivetrain in your Mercedes Benz CLA is beginning to wear out. One of the most common symptoms is a clicking or knocking noise when on full steering lock, which typically indicates a worn outer constant velocity joint. If you instead experience vibrations through the steering wheel or car chassis under acceleration, it may signal that an inner CV joint or the drive shaft itself is out of balance or damaged. It is also vital to inspect the CV boots regularly; a split boot quickly allows dirt to enter and grease to escape, destroying the joint in very little time. By staying alert to these early warning signs, you can prevent more costly repairs and sudden breakdowns along the road.
Common parts to replace on the Mercedes Benz CLA
Depending on driving style and mileage, certain components are more vulnerable than others. In our range for the Mercedes Benz CLA, you will find a broad selection of parts tailored to your specific model. We currently stock 14 matching products for this model series, divided across the following categories:
- Drive shaft Mercedes Benz CLA (8 items) – Complete shafts for a quick and simple replacement.
- Outer CV joint Mercedes Benz CLA (2 items) – To resolve noises when cornering.
- Inner CV joint Mercedes Benz CLA (4 items) – To eliminate vibrations under load.
Replacing a complete drive shaft can often be more time-effective than replacing an individual joint, especially if several components are showing signs of wear. We always recommend inspecting the condition of the entire drivetrain whenever carrying out work on one side of the vehicle.

Frequently Asked Questions about Mercedes-Benz CLA – Drivetrain & Spare Parts
How do I know if my Mercedes-Benz CLA needs a new drive shaft?
The most common signs are vibrations under acceleration or unusual noises when turning. If the vibrations are felt throughout the entire car, it is often the inner joint or the shaft itself that is worn.
Do all CV joints fit every CLA model?
No, there are differences depending on the engine option, gearbox and whether the car has 4MATIC. Always select your car's make, model and engine to ensure the correct fitment.
What causes a clicking noise at full steering lock on a CLA?
This is a classic symptom of a worn outer CV joint. It is often caused by a split CV boot that has allowed dirt and road grime to enter the joint.
Do your CV joint kits include everything needed for the replacement?
Yes, our kits are supplied complete with the joint, CV boot, grease, clamps and mounting hardware to make installation straightforward.
Is it better to replace the complete drive shaft rather than just the joint?
On the Mercedes-Benz CLA, it can often be more economical and reliable to replace the complete drive shaft, as you get new joints at both ends and save time on garage labour.
How often should I inspect the drivetrain on my Mercedes?
We recommend a visual inspection of the CV boots and shafts at every service or tyre change to detect any leaks or tears early.
