To remove the differential from B Series Pickup manufactured from 1989 to 1992, lift the vehicle and support it securely. Remove wheel and tire assemblies. Next, remove the splash shield, drain the differential fluid, and remove the halfshafts. Before unbolting the driveshaft, make a mark on the axle flange. Remove vacuum hoses and electrical connector from freewheel mechanism control box and jack support differential. Take out the crossmember bolts that are located near the lower control arm and lower down the differential/crossmembers assembly assembly from. If necessary, you should remove the crossmembers from the differential and the freewheel mechanism. Reinstall freewheel mechanism if it was removed, then fasten differential to crossmembers for installation. Lift the differential / crossmembers assembly to the proper position, install the crossmember mounting bolts and tighten to 69-85 ft. lbs. After removing the jack, replace the remaining items in reverse order and fill the differential with the correct type and amount of differential fluid. When working on MPV vehicles, the procedures are similar. Raise and support the vehicle, remove the wheel and tire assemblies and splash shield, drain differential fluid, remove halfshafts and mark the driveshaft position, and remove the vacuum hoses and electrical connector. Using a jack, support the differential and take off the bolts/nuts that are securing the differential/freewheel mechanism assembly before lowering it from the vehicle. Keep differential and freewheel mechanism separate, if required. During installation, if the freewheel mechanism had been removed, reinstall it, raise the differential/freewheel mechanism assembly into position, and secure it with bolts/nuts tightened to 49-72 ft. lbs. Reinstall the other components in reverse order. Fill the diff with the right type and quantity of fluid.
