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.
