4C1-32  FRONT WHEEL DRIVE 

 

 

 

 

(5) After the ZERO setting is obtained, rotate the gaging arbor

until the dial indicator rod does not touch the gaging plate. 

 

Record the number the dial indicator needle points to. 

 

 

 

(6) Record the pinion depth code on the head of the drive

pinion. 

  The number indicates a necessary change in the pinion

mounting distance.  A plus number indicates the need for a 

greater mounting distance (which can be achieved by

decreasing the shim thickness).  A minus number indicates

the need for a smaller mounting distance (which can be

achieved by increasing the shim thickness).  If examination

reveals pinion depth code “0”, the pinion is “nominal”.

Note : 
When ordering shims, find the part number in the Parts Catalog by using the thickness of the shims listed 
in the above table. 

 

 

 

 

 
 
 
 

 
 

5. Inner Bearing 
Place the shim on the drive pinion, with the chamfered side 
turned towards the pinion head then install the inner bearing on 
to the pinion using an installer and a press. 

Installer : 9-8522-1165-0  

Note: 
Do not apply pressure to the roller cage. 

Apply pressure only to the inner race. 

 

 

 

6.  Collapsible Spacer  
Discard the used collapsible spacer and install a new one. 

 

 

 

 

 
 
 
 
 
 

9. Oil Seal 
Use oil seal installer to install a new oil seal that has been 
soaked in rear axle lubricant. 

Installer : 9-8522-1275-0  

Note : 
Take care not to use a rear differential oil seal instead of 
the front differential oil seal.

12. Flange Nut and Washer 

 

(1) Apply lubricant to the pinion threads. 

(2) Tighten the nut to the specified torque using the pinion

flange holder. 

Pinion flange holder : 5-8840-0133-0 

Torque N

⋅m (kgf⋅m/lb⋅ft)

177 - 275 (18 - 28/130 - 202) 

Discard used flange nut and install new one. 

 

 

 
 
 

 

 

(3) Pinion bearing preload 

(a) Measure the bearing preload by using a torque meter.  Note

the scale reading required to rotate the flange. 

(b) continue tightening until the specified starting torque is

obtained. 

Starting Torque 

N

⋅m (kgf⋅m/lb⋅in)

0.63 - 1.13 (0.06 – 0.12/5 - 10) 

 

 

 

13. Adjust  Shim 

(1) Attach the side bearing to the differential assembly without

shims.  Support the opposite side using a pilot to prevent

bearing damage.

(2) Insert the differential cage assembly with bearing outer 

races into the side bearing bores of the carrier. 

 

 

 

 

(3) Using two sets of feeler gauges, insert a feeler stock of

sufficient thickness between each bearing outer race and

the carrier to remove all end plat.  Make certain the feeler 

stock is pushed to the bottom of the bearing bores. 

 

Mount the dial indicator on the carrier so that the indicator

stem is at right angles to a tooth on the ring gear.

(4) Adjust feeler gauge thickness from side to side until ring 

gear backlash is in the specified range. 

Backlash mm(in)

0.13 - 0.18 (0.005 - 0.007) 

  With zero end play and correct backlash established,

remove the feeler gauge packs, determine the thickness of

the shims required and add 0.05 mm (0.002 in) to each 

shim pack to provide side bearing preload.  Always use new

shims. 

 

 

 

 

 

(5) Remove side bearing
