Delphi Suspension Ball Joint P/N:TC4252

$32.99

Description

Tighten up your front suspension and steering with the Delphi ball joint TC4252, the front upper joint that drops in as a direct-fit replacement for the 2003-2011 Ford Crown Victoria, 2003-2011 Lincoln Town Car, 2003-2011 Mercury Grand Marquis, and 2003-2004 Mercury Marauder. As the front upper pivot, it connects the upper control arm to the steering knuckle, letting the wheel travel up and down while the front wheels steer. See the Buyer's Guide tab for engine-level details.

Forged for strength: manufactured with high-quality forgings for increased strength and smooth operation.
Chloroprene rubber boot: helps improve durability and guard the joint against premature failure.
Micron-tolerance machining: machined to micron tolerances for durable, smooth joint operation.
Anti-corrosion protection: applied to each part for corrosion prevention and enhanced aesthetics.

Built on Delphi's OE expertise, these parts are tested to withstand temperatures below -40°C and over 120°C plus 720 hours of salt spray. If a worn front upper ball joint is behind clunking over bumps, uneven tire wear, or loose steering, this replaces it. Sold individually — order two to service both front upper positions as a matched pair.
