Product Overview

The rear subframe bushing, OEM number A1663310142, is fitted to the Mercedes-Benz ML-Class (W164 and W166) and GL-Class (X164 and X166), including the GL320 CDI, GL350 BlueTEC 4MATIC, and ML/GLE 63 AMG S-Model. Since this bushing spans two generations across both the ML/GLE and GL platforms, it's a high-turnover part number worth stocking in volume for distributors serving Mercedes-Benz large SUV suspension parts demand.

Worn subframe bushings typically show up as clunking or knocking noise from underneath the vehicle over bumps, a looser overall ride feel, or vibration transmitted into the cabin. GSK Auto manufactures this bushing to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Subframe Bushing?

Function: The subframe bushing mounts the rear subframe to the vehicle's body, isolating road vibration and impact while keeping the subframe securely positioned.

Working Principle: The rubber bushing cushions the connection point between the subframe and body, allowing minor controlled movement while absorbing shock and preventing metal-to-metal contact.

Importance: On a large SUV platform carrying significant weight and load, worn subframe bushings can allow excess movement, reducing ride quality and introducing noise and vibration into the cabin.

Common Failures & Signs: Cracked, dried, or perished rubber causing looseness. Clunking or knocking noise from underneath the vehicle over bumps. Increased vibration transmitted into the cabin. Visible wear or movement at the bushing mounting point.
