Bring the Delphi control arm and ball joint assembly (TC2932) to your front suspension — a front left upper unit that installs as a direct-fit replacement for the 1993-2005 Lexus GS300, 1998-2000 Lexus GS400, 2001-2005 Lexus GS430, and 2002-2010 Lexus SC430. This GS300 control arm locates the front wheel and pairs the arm with an integrated ball joint that pivots to allow steering and suspension travel.
Delphi applies its OE steering expertise to this aftermarket part, with extensive dimensional and material analysis for close compatibility between the OE and aftermarket unit.
- OE-grade validation: 100% crack detection and ultrasonic flaw detection help ensure materials match OE specifications.
- Precision ball stud: machined to micron tolerances for durability and smooth joint operation.
- Robot-welded: consistent welds for repeatable quality.
- Anti-corrosion protection: applied to each part for corrosion prevention and improved appearance.
- Extreme testing: validated below -40 degrees C and over 120 degrees C, plus 720 hours of salt spray.
As a Lexus GS300 control arm, a worn original can cause clunking over bumps, steering wander, vibration, and uneven tire wear; if a failed control arm or ball joint is the cause, this assembly replaces it. Have the suspension inspected to confirm the cause first.
