Lock in dependable four-wheel-drive engagement with the AISIN Locking Hub / Free Wheel Hub, part number FHS005 (this part is listed under both names). It drops in as a direct-fit replacement for the listed applications: the 1989-1991 and 1998 Chevrolet Tracker, the 1989-1997 Geo Tracker, the 1989-1998 Suzuki Sidekick, and the 1994-1997 Pontiac Sunrunner (all engines).
A locking hub connects the front wheel hub to the front axle shaft so the front wheels drive the vehicle in 4WD mode; when unlocked, it lets the front wheels free-wheel to reduce drivetrain drag and wear once you're back in 2WD.
Signs this hub may need replacing include 4WD that won't engage or disengage, a hub that won't lock or unlock, or a front axle that doesn't turn the wheels in four-wheel drive — diagnose the cause first, since other drivetrain parts can produce the same symptoms. The listed applications use two hubs, one per front wheel; this listing is for one unit, so order two and replace both sides together for balanced 4WD operation. Manufacturer part number FHS005.
