Tighten up steering response and quiet a worn front corner with the Delphi control arm and ball joint assembly, MPN TC2135. This is a front left upper control arm with the ball joint pre-installed, designed as a direct-fit replacement for the 1998-2003 Mercedes-Benz ML320, 1999-2001 ML430, 2000-2003 ML55 AMG, 2002-2005 ML500, and 2003-2005 ML350 — see the Buyer's Guide tab for engine-level details.
- OE-derived engineering: built on Delphi's OE safety technology and validated with extensive dimensional and material analysis for close OE-to-aftermarket compatibility; tested below -40°C, above 120°C, and through 720 hours of salt spray.
- 100% inspection: every arm goes through crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball studs: machined to micron tolerances for durability and smooth joint operation.
- Robot-welded for consistent performance, with anti-corrosion protection applied for corrosion prevention and improved appearance.
If a worn ball joint or bushing is behind clunking over bumps, wandering steering, or uneven tire wear on your Mercedes ML350 control arm corner, this assembly replaces the upper arm and joint as one unit.
