• Loose or inconsistent steering response
• Steering linkage movement caused by worn attachment points
• Front-end steering wear on heavy-duty trucks
• Service needs on greaseable steering components

Installation Notes and Quality Assurance

Verify steering linkage alignment, center link attachment diameter, and vehicle ride height before installation. Use the included grease fitting for routine lubrication after installation and during scheduled maintenance. Delphi subjects its OE-focused steering components to extreme temperature and salt-spray testing to evaluate durability and fit consistency for aftermarket use.
