• OE-validated engineering: Delphi applies its OE steering expertise to the aftermarket, testing parts below -40°C and over 120°C and through 720 hours of salt spray, with dimensional and material analysis for OE-to-aftermarket compatibility.
• 100% inspected: every control arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
• Precision ball joint: the ball stud is machined to micron tolerances for durability and smooth joint operation.
• Built to endure: robot welding for consistent quality, plus anti-corrosion protection for corrosion prevention and enhanced appearance.

Positioned as the front left upper rearward unit, this suspension arm locates the wheel and lets its integrated ball joint pivot as the suspension travels. If a worn arm or ball joint is behind clunking over bumps, steering wander, or uneven tire wear, TC1827 replaces the original.
