Product Details

Moog RK622590 is engineered as a replacement suspension control arm and ball joint assembly for rear lower rearward applications on the Ford Expedition and Lincoln Navigator. The stamped steel arm supports suspension geometry, while the included rubber bushings help manage road vibration and noise. Moog builds this part for structural strength and corrosion protection, making it a practical choice for restoring rear suspension function on these full-size SUVs. This part cross-references Ford 7L1Z5A649A for the same application.

Common Issues This Part Can Address

• Rear suspension clunking or looseness
• Worn or cracked control arm bushings
• Ball joint play in the rear lower rearward position
• Uneven rear suspension movement
• Restoration of factory-style rear suspension alignment points

Installation Notes and Tips

Verify vehicle year, make, model, and rear lower rearward position before installation. Because the ball joint uses a press-in mounting type, proper suspension service tools are required for removal and installation. Inspect adjacent rear suspension components, fasteners, and mounting points for wear or corrosion before completing the repair. Confirm alignment after installation on the Ford Expedition or Lincoln Navigator.
