Delphi Suspension Ball Joint P/N:TC409
$27.99

Keep every steering and suspension input tracking true with the Delphi Suspension Ball Joint TC409 — a front lower ball joint that forms the pivoting connection between the control arm and steering knuckle, letting the suspension travel and the wheel steer while helping support and locate the front suspension. This Delphi ball joint is a direct-fit replacement for the 1985-1988 Chevrolet Nova and the 1984-1988 Toyota Corolla; see the Buyer's Guide tab for full engine coverage.

  • Forged strength: Manufactured with high-quality forgings for increased strength and smooth operation.
  • Chloroprene rubber boot: Improves durability and helps prevent premature failure by keeping contaminants out of the joint.
  • Micron-tolerance machining: Machined to micron tolerances for durability and smooth joint operation.
  • Anti-corrosion protection: Applied to each part for corrosion prevention and enhanced aesthetics.

Delphi's OE safety technology is fitted to millions of vehicles worldwide, and this aftermarket steering part draws on that OE expertise — tested to withstand temperatures below -40°C and over 120°C, plus 720 hours of salt spray, with extensive dimensional and material analysis for OE-to-aftermarket compatibility. A worn ball joint may show up as clunking over the suspension, uneven tire wear, or loose steering — if the original joint is the cause, this replaces it.

It uses a chloroprene rubber boot, which improves durability and helps prevent premature failure by keeping dirt and moisture out of the joint.

How is the joint protected against corrosion?

Anti-corrosion protection is applied to each part for corrosion prevention and enhanced aesthetics, and Delphi tests its parts to 720 hours of salt spray.
