Detailed Description

Delphi Professional+ TC5239PX is built for front left upper suspension service on Ford Ranger and related Mazda truck applications. The assembly uses steel construction, rubber bushings, and a machined ball joint mounting design to support consistent suspension geometry under load. Delphi Professional+ parts are developed for fleet and working vehicles, with serviceable components that can be regreased to extend part life and reduce downtime. This part cross-references MOOG Chassis Products CK80054 and Mevotech Supreme CMK80054 for the same application.

The Professional+ line focuses on chassis parts that stand up to repeated use in harsh road and weather conditions. TC5239PX combines a painted control arm, chloroprene rubber dust boot, and pre-greased serviceability to support long-term performance in Ford Ranger and Mazda B2300 applications.

Common Issues Addressed

• Excess suspension play from worn control arm bushings.
• Alignment drift caused by control arm deflection under load.
• Noisy or loose front suspension operation.
• Ball joint wear that affects steering response and tire wear.
• Reduced service life from corrosion and road exposure.

Installation Notes

Verify fitment by year, make, model, and front left upper position before installation. Inspect adjacent suspension components, fasteners, and alignment settings during replacement. Because this assembly is greaseable and includes a grease fitting, service the joint according to the vehicle maintenance schedule after installation.

Quality Assurance

Delphi Professional+ chassis parts are built with premium materials for demanding fleet and working-vehicle use. The serviceable design supports regreasing, which helps extend part life and long-term performance.
