Having 4WD issues on your Ford truck or SUV? This TRQ vacuum solenoid might be the fix. It controls the vacuum to your front locking hubs, engaging and disengaging 4WD. Compatible with a ton of models: 2007-2022 Ford F150, 2011-2021 Super Duty F250/F350, 2007-2020 Expedition, and 2006-2020 Lincoln Navigator (check full list to be sure). Replaces OEM part numbers 7L1Z9H465B, TCA91, SW9319, and others. Made to meet or exceed OE specs, so it should plug right in and work like the original. Symptoms of a bad solenoid include 4WD not engaging, staying stuck in 4WD, or vacuum leaks. Installation is usually straightforward - locate the old solenoid (often near the firewall or inner fender), swap connectors, and mount the new one. Backed by a 2-year/24,000-mile warranty. Get your 4WD working reliably again without the dealership bill.
