Replace a worn front left upper arm with the Delphi control arm TC5445, a control arm and ball joint assembly that links the steering knuckle to the frame and lets the wheel pivot for steering as it moves with the suspension. It fits many vehicles, among them the 1995-2005 Chevrolet Blazer, 1992-2005 GMC Jimmy and 1984-2004 Chevrolet S10, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
Delphi's OE safety technology is fitted to millions of vehicles worldwide, and Delphi applies that OE expertise to its aftermarket steering line. Extensive dimensional and material analysis is used to keep the aftermarket part closely compatible with the OE part.
- Extreme-condition testing: Delphi parts are tested at temperatures below -40°C and above 120°C and are exposed to 720 hours of salt spray.
- Built and inspected: Robot welding gives consistent performance and quality. Every Delphi control arm also undergoes 100% crack detection and ultrasonic flaw detection to check that its materials match OE specifications.
- Precision ball stud: The ball studs are machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: Applied to each part for corrosion prevention and a better appearance.
Signs this part may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, and play at the ball joint. Diagnose the cause first. If the arm or its ball joint is worn, this assembly replaces both. Replacing the left and right sides together is recommended.
