Detailed description

Delphi TC6322PX is engineered to reduce axial deflection under load, which helps preserve alignment and steering response in heavy-use suspension systems. The Professional+ line is aimed at fleet and work-truck duty, with premium materials selected to handle repeated road stress and weather exposure. This part cross-references MOOG Chassis Products (e.g., CK80402) and Mevotech Supreme (e.g., CMK80401) for the same application.

Fits 2004-2008 Ford F-150, front right lower. Fits 2006-2008 Lincoln Mark LT, front right lower. Delphi TC6322PX is a direct-fit suspension service part for these applications and is listed with Professional+ fitment notes.

What it is used for

• Restoring suspension geometry when the original arm is worn or damaged
• Reducing looseness that can affect steering feel and alignment
• Replacing a ball joint assembly with excessive play or noise
• Addressing bushing wear that can contribute to uneven tire wear
• Correcting handling issues caused by suspension component fatigue

Installation notes and tips

Verify the front right lower position, threaded stud style, and adjustable configuration before installation. Confirm the mounting hole pattern and steering type match the vehicle application. Because this assembly uses a press-in ball joint, proper suspension service tools and alignment checks are recommended after installation.

Quality assurance

Delphi Professional+ chassis parts are built for extended service life and reduced downtime in fleet and working-vehicle use. The design includes serviceable components that can be regreased to support long-term performance.
