Detailed description

Delphi TC5998 is a front right upper suspension control arm and ball joint assembly for Chevrolet Colorado and GMC Canyon models equipped with the Sport Package (ZQ8) chassis. The steel arm, threaded ball joint stud, and pre-greased construction are specified for direct suspension service where restoring alignment and joint integrity matters. Delphi applies OE-level dimensional and material analysis to help maintain compatibility with the original suspension layout. This part number, TC5998, is a practical choice when replacing worn upper control arm components on the Colorado or Canyon.

This part cross-references Dorman - OE Solutions (e.g., 521-386) and MOOG Chassis Products (e.g., RK620886) for the same application.

Common issues this part addresses

• Excessive suspension play from a worn upper control arm assembly.
• Clunking or looseness caused by a deteriorated ball joint.
• Uneven tire wear related to suspension geometry problems.
• Steering instability from worn front suspension components.
• Corrosion-related service failure in exposed suspension parts.

Installation notes and tips

Verify the vehicle has the Sport Package (ZQ8) chassis before ordering. Confirm the front right upper position and compare the original part number TC5998 to the removed component. After installation, perform a professional alignment to restore suspension settings.

Quality assurance

Delphi subjects its OE-based steering and suspension parts to temperature extremes below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray testing. That testing supports durability validation for the TC5998 assembly.
