are splined. The differential pinion shaft lock bolt retains the differential pinion shaft in the
differential case.
z A circlip, located on the inboard CV joint stub shaft, holds the halfshaft in the differential case.
When installed, the circlip engages a groove in the differential side gear.
z The rear axle uses SAE 75W- 140 High Performance Rear Axle Lubricant F1TZ-19580- B or
equivalent meeting Ford specification WSL-M2C192- A.
z An embossed metal tag, bolted to the differential housing cover, contains rear axle
identification. For additional information, refer to Section 205 - 00 . Klj . 3 ba

5.
CAUTION: Do not under any circumstance loosen the nut to reduce preload. If it is
necessary to reduce preload, install a new differential drive pinion collapsible spacer
(4662) and nut.
Tighten the nut to set the preload.
zRotate the pinion occasionally to make sure the pinion bearings (4630) (4621) seat
correctly. Take frequent pinion bearing torque preload readings by rotating the drive
pinion gear with a Nm (inch/pound) torque wrench.
z If the preload recorded prior to disassembly is lower than the specification for used
bearings, then tighten the nut to specification. If the preload recorded prior to
disassembly is higher than the specification for used bearings, then tighten the nut to the
original reading as recorded.
z Refer to the torque specification for used pinion bearings in the Specifications portion of
this section.
6. CAUTION: Align the index- marks.
CAUTION: Install the driveshaft with new bolts. If new bolts are not available, apply
Threadlock and Sealer EOAZ-19554- AA or equivalent meeting Ford specification WSK-
M2G351- A5 to the threads of the original bolts.
CAUTION: The driveshaft centering socket yoke fits tightly on the rear axle pinion
flange pilot. To make sure that the yoke seats squarely on the flange, tighten the bolts
evenly in a cross pattern as shown.
Connect the driveshaft. For additional information, refer to Section 205 - 01 . Klj . 4 ba

8.
CAUTION: Differential seal damage will occur if installing the halfshaft without the
special tool.
Install the special tool.
9. Position the halfshaft for installation.
10. Seat the CV joint stub shaft in the differential side gear. 1. Slide the stub shaft into the differential housing until the shaft splines are past the differential seal.
2. Remove the special tool.
3. Align the stub shaft splines and the side gear splines, and slide the stub shaft into the gear until it seats.
„When seated, the axle circlip will lock the stub shaft in the differential side gear.
Check the circlip engagement by attempting to pull the inboard CV joint out of the
differential side gear. If the circlip has not seated, push the CV joint inward until
the circlip is fully engaged in the differential side gear. Klj . 9 ba
