• Description:

  This is the genuine Ford rear differential assembly for the 9.75 inch rear axle used in the F-150, the complete carrier and gear case that splits torque between the rear wheels and allows them to turn at different speeds through a corner. Ford catalogs it as a Differential Assembly, also shown as a Differential Carrier, and this suffix is the limited slip unit for the electronic locking differential with the 3.73 axle ratio on base and mid payload package trucks, superseding the earlier CL3Z-4026-A and CL3Z-4026-G. The assembly contains the case, the side and pinion gears, the clutch pack and the locker actuator interface, all matched to the ring gear and bearing preloads that Ford specifies for this axle. Symptoms that send owners after this part include a chattering, shuddering or banging noise from the rear axle during slow tight turns, one rear wheel spinning freely while the other does nothing on a wet or loose surface, a howl or whine that changes with load, metallic debris found on the differential magnet or in the drained gear oil, and an electronic locker that will not engage or will not release. Worn clutch packs, spun side gears, a cracked case or a failed locker are all terminal conditions for the original unit. Installation is a precision job requiring correct backlash, bearing preload and ring gear pattern, and the axle must be refilled with the specified gear lubricant and, on limited slip units, the correct friction modifier. This is an original equipment Ford assembly machined to factory tolerances. Confirm your axle ratio and payload package before ordering.

• Applications: 9.75 Axle. W/LIMITED SLIP.
