Detailed Description

Delphi TC1503 is a suspension control arm and ball joint assembly made for front left lower service on select compact GM and Suzuki platforms. It uses stamped steel for the arm body and rubber-and-steel bushings to support suspension movement while helping restore steering response and wheel control. The pre-greased ball joint and threaded stud simplify replacement, while the OE-oriented design focus helps match the original part’s dimensions and material requirements. This part cross-references MOOG Chassis Products K201716 for the same application.

Fits 2004-2011 Chevrolet Aveo, front left lower; fits 2006-2011 Chevrolet Aveo5, front left lower; fits 2009-2010 Pontiac G3, front left lower; fits 2009 Pontiac G3 Wave, front left lower; fits 2004-2009 Suzuki Swift+, front left lower; fits 2005-2008 Pontiac Wave, front left lower; fits 2005-2007 Pontiac Wave5, front left lower. Delphi TC1503 is a direct-fit option for these front suspension applications.

What It Helps Address

• Front-end looseness from a worn lower control arm
• Clunking or knocking from deteriorated bushings or ball joint wear
• Uneven tire wear related to suspension geometry issues
• Steering wander or reduced road feel from worn front suspension parts
• Restoration of proper lower control arm support on the front left side

Installation Notes and Tips

Verify the vehicle’s front left lower application before installation and compare the original arm’s dimensions, mounting points, and ball joint style to Delphi TC1503. Because this assembly is non-adjustable, proper alignment should be checked after replacement. Inspect adjacent suspension components, including the opposite side control arm, tie rods, and strut hardware, to confirm the repair addresses the full source of wear.

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 extended salt-spray exposure, to evaluate durability and corrosion resistance. The brand also uses dimensional and material analysis to support OE-style fitment consistency for aftermarket replacement.
