Frequently Asked Questions
Is this the front left upper control arm for a 2003 Ford Expedition?
Yes. Delphi TC5901 is the front left upper control arm for the 2003-2004 Ford Expedition. The front right side is a separate part.
How are the ball studs on the Delphi TC5901 made?
The ball studs are machined to micron tolerances, which supports durability and smooth joint operation. The control arm itself goes through 100% crack and ultrasonic flaw detection.
How was this front left upper control arm tested for heat, cold and rust?
Delphi's parts withstand temperatures below -40 degrees C and over 120 degrees C and are exposed to 720 hours of salt spray. Anti-corrosion protection is applied to each part.
Can a clunk over bumps mean the ball joint on this control arm is worn?
Yes, it can. The ball joint is part of this Delphi TC5901 assembly, so if the joint is the cause, the whole arm is replaced. Have a shop inspect it promptly, since suspension affects steering.
Is the ball joint included with this front left upper control arm?
Yes. The ball joint is part of the assembly, so no separate joint is needed. This listing is one arm; the front right is a separate part.
