OE-derived engineering: Delphi applies its OE steering expertise to the aftermarket, with dimensional and material analysis for close OE-to-aftermarket compatibility. Parts are validated below -40°C, above 120°C, and through 720 hours of salt spray.
Verified materials: 100% crack detection and ultrasonic flaw detection help ensure materials match OE specifications.
Precision ball studs: ball studs are machined to micron tolerances for durable, smooth joint operation.
Robot-welded & protected: robotic welding for consistent quality, plus anti-corrosion protection applied to each part.
The control arm locates the wheel and controls suspension travel, while the built-in ball joint allows steering and suspension movement. Worn signs may include clunking on acceleration or over uneven roads, loose steering, or uneven tire wear.
