- Verified integrity: Each arm undergoes 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
- Consistent build: Robot welding delivers consistent performance and quality, and 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 enhanced aesthetics.
Signs this part may need replacing include clunking on acceleration, deceleration or over bumps, loose or wandering steering, and uneven tire wear from a worn ball joint or bushings. Replace both sides as a pair for balanced handling.
