Detailed Description

Delphi TC4289 is a suspension ball joint for the front lower position on 1995-2002 Ford Crown Victoria, 1995-2002 Lincoln Town Car, and 1995-2002 Mercury Grand Marquis. Delphi applies OE engineering experience to its aftermarket steering and suspension portfolio, with testing that includes sub-zero and high-heat exposure as well as extended salt spray evaluation.
