Detailed Description

Delphi TC7873 is engineered as an OE-style replacement for the front left upper suspension position on Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Silverado 1500, Silverado 1500 LD, GMC Yukon, Yukon XL, Sierra 1500, and Sierra 1500 Limited applications. The aluminum arm construction helps maintain the original suspension geometry, while the included ball joint, bushings, and dust boot support a complete service replacement. Delphi applies dimensional and material analysis to improve OE-to-aftermarket fit, and the part is tested across extreme temperature and salt-spray exposure conditions to verify durability in demanding road environments.

This part cross-references MOOG Chassis Products CK623125 for the same application.

Common Repair Uses

• Clunking or popping from the front suspension
• Excessive play in the upper control arm or ball joint
• Uneven tire wear caused by worn suspension joints
• Steering wander or loose front-end feel
• Cracked bushings or damaged dust boot at the upper control arm

Installation Notes and Tips

Verify the front left upper position before installation and confirm vehicle fitment by year, make, and model. Inspect adjacent suspension components, alignment angles, and fasteners during replacement. Because this assembly is non-adjustable, a professional wheel alignment is recommended after installation to restore proper suspension settings.

Quality Assurance

Delphi builds this suspension control arm assembly using OE-focused engineering and validation methods. The part is subjected to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure, to support consistent performance in real-world conditions.
