Detailed Description

Moog CK80723 is a suspension control arm and ball joint assembly engineered for front left upper replacement service. The stamped steel arm provides a rigid structure, while the rubber bushings help maintain suspension articulation and reduce harshness. The press-in ball joint design and threaded stud configuration support a service-focused OE-style installation on the specified Ford Explorer, Ford Explorer Sport Trac, and Mercury Mountaineer applications.

Moog High Utilization Designs are built for heavier loads and more demanding road conditions, making this assembly a practical choice when the original upper control arm shows wear, looseness, or bushing deterioration. This part cross-references Dorman OE Solutions 521-355 for the same application.

What This Part Helps Address

• Front-end clunking from worn upper control arm components
• Loose or inconsistent steering feel from suspension wear
• Uneven tire wear caused by degraded ball joint or bushing condition
• Suspension noise over bumps and rough pavement
• Loss of alignment stability in the front left upper suspension

Installation Notes and Tips

Install CK80723 in the front left upper position only on the listed applications. Because the ball joint is press-in, proper suspension service tools are required for removal and installation. After replacement, a professional wheel alignment is recommended to verify front suspension geometry.

Confirm vehicle year, make, model, and position before ordering. This part fits 2006-2010 Ford Explorer, front left upper; 2007-2010 Ford Explorer Sport Trac, front left upper; and 2006-2010 Mercury Mountaineer, front left upper.
