Detailed Description

Delphi TC5379 is engineered for front upper suspension service where OE-style fit and material consistency matter. Delphi applies dimensional and material analysis to help ensure proper compatibility between the replacement part and the original suspension layout. The assembly is tested across extreme temperature ranges and exposed to extended salt spray testing to evaluate durability in demanding road conditions. This part cross-references MOOG Chassis Products CK80826 for the same application.

What It Helps Fix

• Front-end looseness or wandering caused by worn upper control arm components
• Clunking or knocking from worn bushings or ball joint wear
• Uneven tire wear related to suspension geometry issues
• Steering instability during braking or cornering
• Excess play in the front upper suspension on GM trucks and SUVs

Installation Notes and Tips

Verify front upper position and vehicle application before installation. The press-in ball joint design requires proper service tools and correct pressing procedures. Inspect adjacent suspension parts, alignment angles, and mounting points during replacement, and perform a wheel alignment after installation.

Quality Assurance

Delphi uses OE-focused engineering practices for its aftermarket steering and suspension portfolio. This part is evaluated for temperature resistance from below -40 degrees C to above 120 degrees C and for corrosion exposure through 720 hours of salt spray testing.
