Purpose and function in the chassis system

The described assembly is responsible for wheel guidance, transferring loads from the body to the ground, and working in conjunction with the braking system on the front left side of the vehicle. The suspension leg with the wheel hub carrier ensures proper wheel geometry, while the integrated disc and caliper enable stable, consistent braking. As a result, this element is a key component for maintaining predictable handling and safe deceleration in the Mercedes B-Class W246.

Set construction and benefits of complete assembly

Combining the suspension leg, wheel hub carrier, disc, and caliper into one assembly simplifies the service process – disassembly and installation take place in one workspace, without the need to source individual parts from different suppliers. This solution:

• facilitates the consistency of mechanically cooperating elements,
• reduces the risk of component mismatch,
• speeds up geometry alignment after repair,
• allows for effectively restoring the factory driving characteristics of the front axle.

For workshops and users, this means a more predictable repair time and a lower risk of additional downtime associated with parts selection.

Compatibility and mounting parameters

The element has been designed specifically for Mercedes B-Class W246 models in the B180 CDI version, intended for the front, left side of the vehicle. The placement on the vehicle is clearly defined, which minimizes the risk of error when selecting the component. The assembly works with the factory suspension and braking system, maintaining the manufacturer's original design concept.

Condition, quality, and application in repairs

The product is offered as a used part, which allows for an economical repair while maintaining the original Mercedes construction. This type of assembly is particularly suitable for:

• post-accident repairs of the front left side,
• mechanical damage to the wheel hub carrier or suspension leg,
• the need to replace a set of steering and braking elements on one wheel.

Choosing an original assembly from dismantling allows you to maintain structural consistency with the other axle elements, which is important for handling stability and uniform operation of the braking system.
