Delphi Suspension Trailing Arm P/N:TC8798
Delphi TC5775 rear upper trailing arm for the 1997-2002 Ford Expedition and other vehicles holds the rear axle in position as the suspension moves.
Clunks over bumps from the rear or uneven rear tire wear can mean a worn suspension trailing arm, though the rear shocks or the rear tires can be behind them too, so find the cause before replacing the arm. Both sides are normally replaced together, and this listing is one arm.
This rear upper trailing arm is a direct-fit replacement for the 1997-2002 Ford Expedition and the 1998-2002 Lincoln Navigator.
