4. Set Tool (Dummy shaft) as shown below and tighten drive
pinion nut carefully to correct preload of 1.1 to 1.4 N´m (11
to 14 kg-cm, 9.5 to 12.2 in-lb).
Tool numbers:
VADummy shaft (KV38100110)
VBCollar (KV38100130)
5. Attach Tool (Height gauge) to gear carrier, and measure the
clearance between the height gauge and the dummy shaft
face.
6. Substitute these values into the equation to calculate the
thickness of the washer.
If values signifying H and D¢are not given, regard them as
zero and calculate.
T (Thickness of washer)=Nþ[(HþD¢) x 0.01] + 3.00
Example:
N = 0.23
H=2
D¢=1
T=Nþ[(HþD¢) x 0.01] + 3.00
= 0.23 þ [(2 þ 1) x 0.01] + 3.00

7. Select the proper pinion height washer.
Drive pinion height adjusting washer:
Refer to SDS, PD-78.
If you cannot find the desired thickness of washer, use
washer with thickness closest to the calculated value.
Example:
Calculated value ... T = 3.22 mm
Used washer ... T = 3.21 mm

3. Install drive pinion height adjusting washer in drive pinion,
and press-fit pinion rear bearing inner cone in it, using press
and Tool.
Tool number: ST30901000
4. Place pinion front bearing inner cone in final drive housing.
5. Apply multi-purpose grease to cavity at sealing lips of oil
seal. Install front oil seal.
Tool number: ST30720000
6. Place drive pinion bearing spacer, pinion bearing adjusting
washer and drive pinion in final drive housing.
7. Insert companion flange into drive pinion by tapping the com-
panion flange with a soft hammer.
8. Tighten pinion nut to the specified torque.
The threaded portion of drive pinion and pinion nut should
be free from oil or grease.

For quiet and reliable final drive operation, the following five
adjustments must be made correctly.
1. Side bearing preload
2. Pinion gear height
3. Pinion bearing preload. Refer to ``ASSEMBLY'', PD-53.
4. Ring gear-to-pinion backlash. Refer to ``ASSEMBLY'',
PD-54.
5. Ring and pinion gear tooth contact pattern
Side Bearing Preload
A selection of carrier side bearing preload shims is required
for successful completion of this procedure.
1. Make sure all parts are clean. Make sure, also, the bearings
are well lubricated with light oil or type ``DEXRON
TM'' auto-
matic transmission fluid.
2. Place the differential carrier, with side bearings and bearing
races installed, into the final drive housing.
3. Put the side bearing spacer in place.
CAUTION:
Side bearing spacer is placed on either the right or left
depending upon final drive gear ratio. Be sure to replace it
on the correct side.
4. Use Tool to place original carrier side bearing preload shims
on the carrier end, opposite the ring gear.
