Help keep steering tight and the corner steady with the Delphi ball joint TC2317, a front left lower suspension ball joint that pivots the steering knuckle against the control arm for your listed Lexus. It is a direct-fit replacement for many vehicles, among them the 2002-2010 Lexus SC430, 1998-2005 Lexus GS300 and 2001-2005 Lexus GS430 — see the "Vehicles it fits" section for the full list and engine-level detail.
- Forged strength: Manufactured with high-quality forgings for increased strength and smooth operation.
- Chloroprene boot: A chloroprene rubber boot improves durability and helps prevent premature failure.
- Micron tolerances: Machined to micron tolerances for durable, smooth joint operation.
- Corrosion protection: Anti-corrosion protection is applied to each part for corrosion prevention and enhanced aesthetics.
Delphi applies its OE expertise to its aftermarket steering portfolio, testing to the extreme: parts withstand temperatures below -40°C and over 120°C and endure 720 hours of salt spray, with dimensional and material analysis for OE-to-aftermarket compatibility. If a worn front left lower ball joint is behind clunking, wandering steering or uneven tire wear, this is the direct-fit replacement.

Where does this ball joint mount?
It is the front left lower ball joint, connecting the lower control arm to the steering knuckle so the knuckle can pivot and move through suspension travel.
What are signs this ball joint may need replacing?
Clunking over the road, wandering or loose steering, and uneven or accelerated tire wear can be signs of a worn ball joint. Have the cause diagnosed before replacing.
What kind of boot does this ball joint use?
It uses a chloroprene rubber boot, which Delphi states improves durability and helps prevent premature failure of the joint.
Is the Delphi ball joint tested for durability?
Delphi tests to OE standards: the parts withstand temperatures below -40°C and over 120°C and endure 720 hours of salt spray, and are machined to micron tolerances.
