Econoline E550 V10-6.8L VIN S (2003)
5. Force the differential ring gear into mesh with the pinion, to obtain an indicator reading. Record the reading.
6. Remove the special tools and the differential case from the differential housing.
7. Remove the Dummy Bearings from the differential case.
8. Place one shim, of the necessary thickness, as determined from the previous measurement, on the differential ring gear side of the differential case.
If additional shimming is necessary, beyond what the hardened differential bearing shim can provide, select and install a different thickness
outboard spacer.
9. Using the special tool, install the differential bearing on the differential ring gear side of the differential case.
10. Determine the correct shim thickness and place it on the differential case hub on the drive pinion side.
^
To determine the correct shim thickness, first, subtract the reading of the previous measurement from the total differential case end play
reading obtained under Differential Case End Play Check. Then, add 0.25 mm (0.010 inch) to this amount. This is the correct thickness shim
to place on the hub. If additional shimming is necessary, beyond what the hardened differential bearing shim can provide, select and install a
different thickness outboard spacer.
