Product Overview

The body mount bushing, OEM number A1663310042, is the front body mounting bushing fitted to the Mercedes-Benz GL-Class (X164), 2006 onward, and the ML-Class (W164), 2004-2011. This bushing sits between the vehicle's body and frame on this body-on-frame SUV platform, and since it's used at multiple mounting points per vehicle, it's a steady, recurring part for anyone servicing this generation of Mercedes SUVs.

Worn or deteriorated units typically show up as clunking or knocking noises over bumps, a loose or shifting feeling in the body relative to the frame, or visible cracking and sagging in the rubber bushing material during inspection. GSK Auto manufactures this body mount 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.

(Confirm against your VIN or chassis code before ordering - this bushing is used at multiple body mounting points per vehicle, so it's worth confirming with your customer how many units they need for their specific repair.)

What Is a Body Mount Bushing?

Function: The body mount bushing isolates the vehicle's body from the frame on body-on-frame construction, absorbing road vibration and noise before it transfers from the chassis into the passenger cabin.

Working Principle: The rubber bushing sits compressed between the body and frame at each mounting point, flexing slightly to absorb road impacts and vibration while still keeping the body securely attached to the frame during normal driving and handling.

Importance: On a body-on-frame SUV like the GL-Class and ML-Class, these bushings are essential for ride comfort and noise isolation, and as they age and deteriorate, both ride quality and structural connection between body and frame can be affected.

Common Failures & Signs: Rubber material cracking, hardening, or sagging from age and weather exposure. Clunking or knocking noise over bumps and uneven road surfaces. A loose or shifting feeling in the body relative to the frame. Increased road noise and vibration transferred into the cabin.
