I believe that this sets the proper center distance. I am no too sure what to do with the upper one since it changed on the 1969 models but it appears to have the same bearing so I will replace that too, as it feels a little wonky now that it is installed. For the upper shims I may just go for a solid drag on the steering knuckle but maybe not as much as required for early models (20-22 lbs). That is a snug bearing. Any thoughts out there? ...
The process is not that different.
There's another service manual in the Patrolabilia section: is the 19787 Service Manual that was uploaded by member azsteve (where are you?). It has this procedure in Section FA for the knuckle bearings, that applies in your case:
---------
INSTALLATION
Install front axle in reverse order of removal,
noting the following:
1. Install bearing race, place bearing race in
position and tap race lightly until it seats in axle
housing.
2. Dip knuckle flange roller bearings in grease.
Fit O-ring on each knuckle flange cap. Press in
greased roller bearing to knuckle flange cap.
3. Place knuckle flange on axle housing with
steering knuckle arm toward front of vehicle.
4. Install upper and lower bearing caps on
knuckle flange with shims. Adjust upper and
lower shims so that knuckle flange turning torque
is 1.0 to 2.9 N-m (10 to 30 kg-cm, 8.7 to 26.0
in-lb).
Note: Evenly distribute total number of shims to
upper and lower bearing caps. Failure to
do so may cause misaligned centering of
inner and outer shafts, resulting in undue
strain on and wear of parts.
Available adjusting shim
Thickness mm (in)
0.075 (0.0030)
0.127 (0.0050)
0.254 (0.0100)
0.762 (0.0300)
5. Equally tighten four nuts securing cap until
bearing cone does not turn when knuckle flange is
turned back and forth.
Tightening torque:
Knuckle flange cap fixing nut:
19 to 21 N m
(1.9 to 2.1 kg-m, 14 to 15 ft-lb)
6. Torque load for turning knuckle flange at
edge of steering knuckle arm is 44 to 98 N (4.5 to
10 kg, 10 to 22 lb). Add or remove shims to
upper bearing cap until correct turning load is
obtained. When measured resistance is low, re-
move shim(s); when it is high, add shim(s).
7. Place grease seal on knuckle flange. Install
bolts that secure grease seal guard to knuckle
flange.
Tightening torque:
Grease seal guard fixing bolt:
10 to 11 N.m
(1.0 to 1.1 kg-m, 7 to 8 ft-lb)
