When your four-wheel-drive hubs depend on a working solenoid to lock, the Dorman 4WD hub locking solenoid, part number 600-400, is built as a direct replacement for the original equipment solenoid. It fits many vehicles, among them the 1997-2018 Ford F-150, 1997-1999 Ford F-250 and 1995-1996 Ford Explorer. See the "Vehicles it fits" section for the full list.
Dorman also lists this unit as a 4WD engage and emissions purge solenoid, so you may find it under either name.
- Direct replacement: Designed to match the original solenoid's fit and function on the listed applications.
- Effective fix: If a failed original solenoid is behind your 4WD control problem, this replacement is intended to return control of the 4WD system.
- Thoroughly tested: Goes through on-vehicle and laboratory testing aimed at trouble-free operation.
- Trustworthy quality: Supported by Dorman's team of designers and engineers in the United States.
Signs this solenoid may need replacing include four-wheel drive that won't engage or disengage, or hubs that fail to lock when 4WD is selected. Other components can cause the same symptoms, so diagnose the cause before replacing the solenoid.
