Detailed Fitment and Function

URO 1073301207 is a front left lower suspension control arm engineered to restore proper wheel alignment, directional control, and braking stability. It is a direct-fit replacement for 1981-1985 Mercedes-Benz 380SL, 1981 Mercedes-Benz 380SLC, and 1975-1976 Mercedes-Benz 300D applications. The OE-style geometry helps maintain suspension angles, while the durable alloy metal construction supports long-term service in demanding road conditions. This part number, 1073301207, is also cross-referenced as URO-010389 for the same application.

What This Control Arm Helps Address

• Front-end looseness or wandering caused by worn suspension joints
• Uneven tire wear related to incorrect alignment geometry
• Clunking or play from a worn lower control arm assembly
• Reduced braking stability from suspension wear at the front left corner
• Steering pull or inconsistent directional control on Mercedes-Benz 380SL, 380SLC, and 300D models

Installation Notes and Tips

Install this control arm at the front left lower position and verify that the ball joint stud and locking nut match the vehicle’s existing hardware specifications. Because the arm is non-adjustable, a professional wheel alignment should be performed after installation to confirm suspension geometry. Inspect adjacent bushings, mounting points, and steering components before reassembly to avoid repeat repairs.

Quality Assurance

URO backs this control arm with a 24-month unlimited mileage warranty. The design uses high-strength alloy metal construction and OE control arm geometry to support correct fitment and consistent suspension performance on Mercedes-Benz 380SL, 380SLC, and 300D applications.
