Keep the rear wheel precisely located and suspension movement controlled with the Delphi control arm and ball joint assembly, MPN TC7188. This rear upper forward unit drops in as a direct-fit replacement for many Lexus models, among them the 2002-2010 Lexus SC430, 1998-2005 Lexus GS300 and 2001-2005 Lexus GS430; see the Buyer's Guide tab for the full list. Delphi applies the OE expertise behind its safety technology, fitted to millions of vehicles worldwide, with extensive dimensional and material analysis for close compatibility between the OE and aftermarket part.

  • Tested to the extreme: validated below -40°C and above 120°C and exposed to 720 hours of salt spray for OE-level performance.
  • Inspected to OE specifications: 100% crack detection and ultrasonic flaw detection confirm the materials match OE.
  • Micron-tolerance ball studs: machined to close tolerances for durability and smooth joint operation.
  • Robot-welded with anti-corrosion protection: consistent welds plus anti-corrosion protection applied to each part for corrosion prevention and enhanced aesthetics.

If a worn control arm or a loose ball joint on your 1998-2005 Lexus GS300 is the cause of clunking, uneven tire wear, or wandering steering, this assembly replaces both in one unit. Torque all fasteners to spec and have the alignment checked after installation.
