Steer with confidence and keep your front suspension tight with the Delphi control arm and Ball Joint Assembly (TC2522), a front lower control arm with an integrated ball joint that locates the wheel, sets suspension geometry, and pivots the steering knuckle through its travel. It installs as a direct-fit replacement for the 2008-2015 Smart Fortwo — see the Buyer's Guide tab for engine-level detail.
This control arm and ball joint assembly draws on Delphi's OE-derived engineering, tested to the extreme: parts endure temperatures below -40°C and above 120°C plus 720 hours of salt spray, with dimensional and material analysis for close OE-to-aftermarket compatibility.
- OE-matched materials: 100% crack detection and ultrasonic flaw detection help confirm materials match OE specifications.
- Precision ball studs: ball studs machined to micron tolerances for durability and smooth joint operation.
- Robot welded: consistent welds for repeatable performance and quality.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
Signs this part may need replacing include clunking on acceleration or over bumps, loose or wandering steering, and uneven tire wear. If a worn control arm or ball joint is the cause, this assembly replaces it. Sold individually; order two to replace both sides as a matched pair.
