Help maintain precise steering and stable wheel geometry with the Delphi control arm (MPN TC2933), a front right upper suspension control arm and ball joint assembly. It drops in as a direct-fit replacement for many Lexus models, among them the 2002-2010 Lexus SC430, 1993-2005 Lexus GS300 and 2001-2005 Lexus GS430 — see the Buyer's Guide tab for the full list and engine-level details. The control arm locates the wheel while the integrated ball joint allows the pivoting motion of the steering; clunking over acceleration, uneven tire wear, or loose, wandering steering can be signs this control arm assembly may need replacing.
- OE-derived testing: Delphi applies its OE steering expertise to the aftermarket, validating parts below -40°C, above 120°C and through 720 hours of salt spray, with dimensional and material analysis for OE-to-aftermarket compatibility.
- Quality-checked material: Each control arm undergoes 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball stud: Ball studs are machined to micron tolerances for durability and smooth joint operation.
- Built consistent: Robot welding delivers consistent performance, and anti-corrosion protection is applied to each part for corrosion prevention and enhanced appearance.
