Wheel Carrier Mercedes W208 R170 Rear Left N/S Wheel Hub Bearing A2023509408

Wheel Carrier Mercedes W208 R170 Rear Left N/S Wheel Hub Bearing is an original suspension component designed for installation on the rear left side of the vehicle. Thanks to its factory-spec construction, it ensures correct suspension geometry, stable handling, and precise seating of the hub and bearing, which translates into safe and predictable operation of the rear axle. It is a practical solution for repairs following mechanical damage or wear of load-bearing suspension components.

Purpose and function in the suspension system

The described rear left wheel carrier is a load-bearing component that connects the wheel hub to the other suspension and braking system components. In Mercedes W208 and R170 models, it is responsible for:

• maintaining the correct wheel position relative to the body,
• stable mounting of the hub and bearing,
• transferring loads from the wheel to the control arms and the body,
• maintaining proper wheel alignment and camber angles.

Thanks to its dedicated placement on the rear left side of the vehicle, the wheel carrier is matched to the geometry of the specific axle, which facilitates installation and reduces the risk of suspension alignment issues after replacement.

Construction and compatibility with the chassis

The wheel carrier is integrated with the hub and wheel bearing, allowing the entire assembly to be replaced in a single service operation. This solution:

• simplifies the installation process compared to replacing individual components,
• reduces the risk of play resulting from improper bearing seating,
• ensures consistent operation of the hub and bearing with the rest of the suspension.

Its original Mercedes origin helps maintain factory handling parameters, which is particularly important in vehicles with precisely tuned suspension.

Application in Suspension Repair Kits

This item belongs to the Suspension Repair Kits category, making it an excellent choice for comprehensive rear axle repairs – for example, after mechanical damage, corrosion, or operational wear. Replacing the complete wheel carrier with the hub and bearing is particularly beneficial when:

• play or noise has been detected within the wheel bearing,
• the load-bearing component has been bent or cracked,
• it is necessary to restore proper geometry after a collision or impact with an obstacle.

This approach reduces the number of disassembly and re-adjustment steps while increasing confidence that the entire suspension section works cohesively.

Characteristics of the used component

The presented wheel carrier is a used part, which in practice offers a favorable compromise between repair costs and maintaining the manufacturer's original design. In the case of suspension, this is often a better solution than cheaper replacements with uncertain stiffness or manufacturing tolerances. A used OEM component allows you to maintain:

• factory mounting points for control arms and shock absorbers,
• the appropriate stiffness of the entire wheel assembly,
• predictable vehicle behavior during braking and cornering.

Selecting a used wheel carrier and technical support

When selecting a rear left wheel carrier for a specific Mercedes version, it is crucial to match it to the body style, suspension type, and mounting side. Proper matching is facilitated by the manufacturer's markings and interchangeable numbers assigned to this reference, which are detailed in the product's technical specifications. If in doubt, it is worth comparing the geometry and mounting points with the part removed from the vehicle.

If you are planning a comprehensive repair or upgrade of the rear axle suspension zone in your Mercedes and need other components from the same group, such as control arms, springs, or shock absorbers, check the available parts in the Mercedes Suspension Repair Kits category.

For drivers considering the installation of used suspension components, it will be useful to compare stock and sports solutions and discuss the criteria for safe part selection – this is described in detail in the article "Stock vs. sports suspension – differences in construction and is it worth buying used suspension parts?", which will help you consciously plan the repair or upgrade of your chassis.
