Toyota 8 Inch E-Locker Differential Master Overhaul Kit

A master overhaul kit for the Toyota 8-inch rear differential with the factory electric locker, kit number TACLOC-SPC. Listed fitment is the 1996-2009 4Runner, 2007-2009 FJ Cruiser, 2003-2009 Lexus GX470, 2000-2006 Tundra 4WD and 1993-1998 T100 4WD.

The kit has the pinion head and tail bearings, both carrier bearings, pinion and axle seals, setup shims, a new pinion nut, ring gear bolts, gear marking compound and sealant. It comes with a solid spacer in place of the factory crush sleeve, so once pinion preload is set with shims it stays put instead of relaxing over time.

Rebuild when the rear axle whines on the gas or coast, clunks on and off throttle, or shows play at the pinion yoke. It is also the kit to have on the bench any time you regear an 8-inch locker axle, since the old bearings should not go back on a new pinion.

Setup is the normal routine: set pinion depth with the head shim, shim the pinion to get correct preload against the solid spacer, install the carrier with new bearings, then adjust backlash and read the pattern with the marking compound before torquing the ring gear bolts and closing the housing.
