Idler Arm for 1997-2003 Ford F-150 & More - Delphi TL537

Help firm up loose, wandering steering with the Delphi Idler Arm (TL537), a direct-fit replacement for the listed applications. It fits many vehicles, among them the 1997-2003 Ford F-150, the 1997-1999 Ford F-250 and the 1997-2002 Ford Expedition; see the Buyer's Guide tab for the full list. Working opposite the pitman arm, the idler arm helps support the steering center link and keep the linkage aligned so the wheels track where you point them.

• OE-derived engineering: Delphi applies its OE steering expertise to this aftermarket unit, backed by dimensional and material analysis for close compatibility with the original part.
• Extreme-condition tested: validated below -40°C and above 120°C and exposed to 720 hours of salt spray.
• Micron-machined ball stud: the ball stud is machined to micron tolerances for durable, smooth joint operation, and the arm is fatigue tested to help avoid failure.
• Anti-corrosion protection is applied to each part for corrosion prevention and improved appearance; the necessary accessories for the job are included.

Signs this idler arm may need replacing include excessive steering play, a wandering feel, or uneven tire wear. If a worn idler arm is the cause, this replaces it.
