Mercedes-Benz Control Arms & Parts

Control Arms and Bushings at a Glance

This category includes genuine Mercedes-Benz control arms, bushings, struts, and mounting hardware for select models. OEM control arms are designed for each model's suspension geometry, supporting precise steering, stable handling, and even tire wear.

Control arms connect the wheels to the vehicle's body and guide suspension movement. Many Mercedes-Benz models use multi-link suspensions with several arms at each corner, and worn bushings or ball joints can cause clunks, wandering, vibration, or uneven tire wear. Control arm work often goes hand in hand with ball joints and tie rod linkages.

Arms, Bushings, and Suspension Links

• Upper and lower control arms
• Thrust arms, tension struts, and suspension links
• Control arm bushings
• Control arms with integrated ball joints
• Mounting bolts, nuts, and eccentric hardware

Why Genuine Control Arms Preserve Handling

Genuine Mercedes-Benz control arms are built to the original geometry, bushing stiffness, and ball-joint design of the models they are designed for. That helps the vehicle steer and track the way it was engineered. Aftermarket arms may use different bushing materials or tolerances, which can change ride comfort, noise, or wear life. OEM parts help keep suspension behavior consistent side to side.

Identifying the Right Control Arm for Your Vehicle

Enter your year, model, trim, and engine, then confirm position: front or rear, upper or lower, left or right. Drivetrain and suspension package matter, since 4MATIC, AMG, and air-suspension models may use different arms. Search by part number or confirm with your VIN for the most reliable match.

Suspension Design and Drivetrain Differences

Control arm fitment can vary by model, body style, drivetrain, suspension type, and model year. Some fasteners are designed for one-time use, so check the service information and replace hardware as specified. Confirm fitment before purchase and plan an alignment afterward. While the suspension is apart, inspect sway bars and coil springs.

Control Arm Shopping Essentials

• Includes control arms, bushings, struts, and hardware.
• OEM arms match original geometry and bushing design.
• Confirm position, side, drivetrain, and suspension type.
• Replace one-time-use fasteners as specified.
• An alignment is recommended after replacement.

Mercedes-Benz Control Arm Questions

What are the signs of worn control arms on a Mercedes-Benz?

Clunking over bumps, loose steering, vibration under braking, and uneven tire wear can point to worn arms or bushings.

Should control arms be replaced in pairs?

Many technicians recommend replacing both sides together to keep handling balanced, especially at higher mileage.

Can I replace only the bushing?

Some bushings are serviceable separately, while others require a complete arm. Check the listing and your technician's recommendation.

Are OEM control arms worth it?

OEM arms preserve factory geometry and ride quality and help ensure correct fit.

Do I need an alignment after control arm replacement?

Yes. An alignment is recommended to restore correct steering and tire wear.
