Detailed Description

Delphi applies OE-focused dimensional and material analysis to its aftermarket steering and suspension portfolio, and this TD1239W bushing follows that approach for front lower inner control arm service. The rubber construction is selected for suspension isolation, while the press-fit design supports a secure fit in the control arm assembly. For Mercedes-Benz ML320, ML430, ML500, ML55 AMG, and ML350 models, Delphi TD1239W helps restore the intended bushing interface at the front lower inner position. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Installation Notes and Tips

Verify the control arm position before ordering, since this part is specified for the front lower inner location only. Press-fit bushings require proper removal and installation tools to avoid damage to the control arm or the new bushing. Confirm dimensions and OE reference numbers during service, and compare the existing bushing to Delphi TD1239W before installation.

Quality Assurance

Delphi states that its OE safety technology is used on millions of vehicles worldwide and that its aftermarket parts are tested for temperature extremes below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure. Delphi TD1239W is supported by OE-focused material and dimensional analysis for fitment consistency.
