Toyota Pickup and 4Runner Manual Locking Hubs, 1986-1995

This is a pair of manual front locking hubs for the 1986-1995 Toyota Pickup 4x4 and 4Runner 4x4, including the SR5, DLX and Turbo models with the 2.4L and 3.0L engines. The listing also covers the 1993-1995 T100 4x4 and the 1987-1989 Toyota Van 4WD. They replace Toyota 43508-35050 and 43509-35050. Each hub has a FREE / LOCK dial, and you get both the left and the right side.

On these trucks you turn the hubs to LOCK before you shift the transfer case into 4WD. When the hubs are FREE, the front axle shafts and differential do not turn while you drive in 2WD. Old hubs wear at the inner splines and the clutch ring. The common signs are a hub that clicks or slips under load in LOCK, a dial that is seized or will not stay in position, grease leaking past the cover, and a front end that does not pull even though the dials say LOCK.

To swap them, set the dial to FREE and raise the front of the truck. Remove the hub cover fasteners and the cone washers (a light tap with a brass punch frees the washers), then pull the hub body off. Clean the mating face, use a new gasket, and put a light film of grease on the inner splines. Slide the new hub on, reinstall the washers and fasteners, and tighten them evenly. Turn each dial to LOCK, spin the tire by hand to make sure the axle turns with it, then set both back to FREE for road driving.
