Econoline E350 1 Ton V8-5.4L Prop SOHC VIN Z (1998)
6. After the correct feeler gauge feel is obtained, check the reading. This is the thickness of pinion shims required providing that, upon inspection of
the service pinion gear, there are no markings.
NOTE: If the service pinion gear is marked with a plus (+) reading, this amount must be subtracted from the thickness dimension obtained
between the gauge block and gauge tube.
NOTE: If the service pinion gear is marked with a minus (-) reading, this amount must be added to the thickness dimension obtained between the
gauge block and gauge tube.
NOTE: In addition, you must use the same new inner pinion bearing used in the previous steps.
7. Remove the inner pinion bearing cup and install the correct thickness of pinion shims in the rear axle differential carrier bore.
CAUTION: The drive pinion preload spacer and pinion shim assembly sequence must be followed. If the sequence is not followed, unit failure
can result. If pinion shims are damaged, replace them with new ones. Shims are available in the thicknesses shown in the chart.
NOTE: If the oil slinger is used, replace it with a new one upon assembly and measure it as part of the shim stack.
8. Reinstall the inner pinion bearing cup. Install the oil slinger, if so equipped, between the pinion gear head and inner pinion bearing cone.
9. Press on the pinion bearing with the Axle Bearing/Seal Plate and one of the following:
-
The Pinion Bearing Cone Replacer for Model 70.
-
The Axle Bearing Seal Replacer for Model 60.
-
For Model 80 rear axles, use a suitable plate which contacts the bearing.
10. Assemble the pinion shims onto the pinion and install the drive pinion into the rear axle housing. Assemble the outer pinion bearing onto the drive
pinion.
NOTE: The thickness of the old shims may be used as a starting point for the pinion bearing preload shims.
