Help keep the rear suspension geometry tight and quiet with the Delphi control arm, MPN TC6607. This is the rear lower forward control arm, and it drops in as a direct-fit replacement for the 2007-2013 Ford Expedition and 2007-2012 Lincoln Navigator (see the "Vehicles it fits" section for engine-level fitment).
Delphi carries its OE expertise into the aftermarket, testing to the extreme for OE performance: parts endure temperatures below -40°C and above 120°C plus 720 hours of salt-spray exposure, while extensive dimensional and material analysis keeps the aftermarket piece matched to the original.
- Verified materials: 100% crack detection and ultrasonic flaw detection confirm the materials match OE specifications.
- Robot-welded: welding is robot-performed for consistent quality unit to unit.
- Precision ball studs: ball studs are machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
A worn control arm can show up as clunking on acceleration or over uneven pavement, uneven tire wear, or loose handling; if a failed arm is the cause, this replaces it. Sold individually; the left and right sides work as a pair, so inspect both.
