Keep your rear suspension located and your ball joint moving smoothly with the Delphi Suspension Control Arm TC3641, a rear lower Delphi control arm built with the company's OE expertise. It fits many vehicles, among them the 2003-2012 Toyota 4Runner, 2007-2012 Toyota FJ Cruiser and 2010-2012 Lexus GX460, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine-level fitment.

It carries the OE safety technology Delphi fits to millions of vehicles worldwide, tested to the extreme for OE performance:

  • Extreme validation: withstands temperatures below -40°C and over 120°C and endures 720 hours of salt spray, with extensive dimensional and material analysis for OE-to-aftermarket compatibility.
  • 100% inspected: every arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
  • Robot-welded: welded by robot for consistent performance and quality.
  • Precision ball studs: ball studs machined to micron tolerances for durability and smooth joint operation.
  • Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.

If a worn or damaged rear lower control arm is behind clunking over bumps, uneven tire wear, or loose steering, this replaces it. Replacing the arms on both sides together is recommended. Interchange: 524-211 · 48720-35060 · 48720-35061
