Econoline E350 1 Ton V8-5.4L CNG VIN M (1999)
8. Tighten the forcing screw so the differential side gears move away from the differential pinion gears and relieve the loaded condition.
9. While holding the differential pinion gears in place, insert the special tool into the hole of the differential pinion shaft in the differential case. Pull
on the handle, rotating the differential case and allowing the differential pinion gears to rotate and enter into the differential case.
10. Adjust the forcing screw by very slightly loosening or tightening it until the required load is applied to allow the differential side gears and
differential pinion gears to rotate.
11. Rotate the differential case until the holes of both differential pinion gears are aligned with those of the differential case.
12. CAUTION: Do not overtighten the forcing screw. Overtightening the forcing screw can damage the rear axle disc and plate kit.
Apply torque to the forcing screw for clearance to assemble the differential pinion thrust washers.
