Mercedes-Benz A CLK Class W168 C209 Wheel Bolts Rear Front Set A2034000170

Mercedes-Benz A / CLK Front and Rear Wheel Bolt Set is an original mounting kit designed for the front and rear axles of selected Mercedes models. Thanks to its factory design, it ensures correct wheel seating, stable load transfer, and safe operation of the running gear. This is a practical solution for wheel changes, brake servicing, or completing missing mounting elements.

Application and Technical Function

The wheel bolts in the Mercedes-Benz A / CLK Class set are responsible for precisely pressing the wheel rim against the hub on both the front and rear axles. The OEM design is adapted to the hub geometry, wheel rim seats, and suspension characteristics, which reduces the risk of wheel wobble, play, or uneven tire wear.

These components are particularly important for:

• Brake system servicing (disc, drum, hub removal),
• Changing steel wheels to alloy wheels or vice versa,
• Replacing missing bolts after previous repairs,
• Checking wheel mounting after intensive use.

Construction and Fitment for Front and Rear Axles

The set has been prepared for operation on the front and rear axles, which simplifies servicing – there is no need to select different types of bolts for individual wheels. The uniform thread geometry and support cone ensure consistent mounting conditions throughout the vehicle, promoting even force distribution during braking and acceleration.

Original origin from the Mercedes group means the bolts are designed for specific wheel and hub parameters, without the need for spacers or modifications. This is the preferred solution for workshops that prioritize assembly consistency and predictable vehicle behavior.

Performance Characteristics and OEM Advantages

Compared to random aftermarket parts, factory wheel bolts provide:

• Material consistency with other running gear components,
• Appropriately selected working thread length relative to the hub,
• Correct cone angle cooperating with the seat in the wheel rim,
• Easier torque control during servicing.

This minimizes the risk of thread damage in the hub, wheel rim deformation, or the formation of unwanted play after extended use. This is especially important in cars where the running gear operates under higher loads, e.g., during dynamic highway driving.

Component Condition and Practical Installation Tips

The wheel bolt set is offered as a used OEM part, which in practice means factory fitment while maintaining a favorable cost-to-quality ratio. Before installation, the standard workshop procedure is recommended: cleaning the hub seats, checking the thread condition, and applying the appropriate tightening torque according to the service documentation for the specific model.

In daily operation, it is advisable to periodically check the condition of the bolts – especially after seasonal wheel changes or after intensive vehicle use. Properly selected and tightened bolts reduce the risk of steering wheel vibrations, noises from the wheel area, and accelerated wear of suspension components.
