Mercedes X164 W164 Rear Driveshaft Drive Shaft Right O/S Side OM629 A1643500110

Mercedes X164 W164 Rear Driveshaft Drive Shaft Right O/S Side OM629 is an original drivetrain component designed to work with the OM629 engine unit. Engineered by the vehicle manufacturer, it ensures proper torque transmission to the rear axle, stable drivetrain operation, and compatibility with factory suspension and axle parameters. This is the solution for users who want to maintain the OEM design and avoid issues typical of generic replacements.

Purpose and vehicle placement

The presented driveshaft belongs to the Driveshafts category and is intended for installation in the rear of the vehicle, on the right side. It is responsible for transmitting power from the differential to the wheel, working in conjunction with the suspension and axle components in Mercedes X164 and W164 class models with the OM629 engine. Precise fitment to the specific side of the vehicle reduces the risk of improper installation, and maintaining the factory geometry of the drivetrain improves operating smoothness, reduces vibrations, and ensures the correct functioning of traction and stability control systems.

Advantages of using an original driveshaft

Choosing an original driveshaft for your Mercedes allows you to maintain the integrity of the entire drivetrain. A component designed for a specific model and engine unit ensures:

• correct length and geometry relative to the axle and wheel hub,
• proper torque transmission under loads typical for the OM629 engine,
• compatibility with factory joints and mounts,
• reduced risk of improper fitment characteristic of universal replacements. As a result, the drivetrain operates stably, and the risk of additional stress on the differential, wheel bearings, or suspension components is minimized. This is particularly important in heavier SUV-class vehicles, where the drivetrain is under significant load.

Characteristics of the used component

The offered driveshaft is a used part, which allows for economical repair while maintaining the manufacturer's original specifications. In practice, this means the ability to replace a damaged or worn shaft with an OEM part with a similar level of wear, without the need to invest in expensive refurbished solutions or unreliable replacements. Choosing a used OEM component is particularly beneficial in situations where the priority is to maintain the factory drivetrain design while optimizing service costs during rear axle and differential repairs.

Support for drivetrain diagnostics

When replacing a driveshaft, it is worth simultaneously assessing the condition of the differential, bearings, and other drivetrain components. In the case of symptoms such as whining, humming, or vibrations from the rear of the vehicle, our guide on selecting original used parts will be helpful. More information can be found in the article Humming differential – why a used OEM axle is a sensible choice, which discusses the practical aspects of drivetrain repairs using original parts.
