REMOVAL
1. Remove the front final drive assembly. Refer to
DLN-215, "Removal and Installation".
2. Remove the carrier cover bolts and separate the carrier cover from the gear carrier using Tool.
CAUTION:
 Do not damage the mating surface.
 Do not insert flat-bladed screwdr iver, this will damage the
mating surface.
INSTALLATION
1. Apply 3 mm (0.12 in) bead of sealant to the mating surface of the carrier cover as shown.
 Use Genuine Silicone RTV or equivalent. Refer to GI-15,
"Recommended Chemical Products and Sealants".
CAUTION:
Remove any old sealant adheri ng to the mating surfaces.
Also remove any moisture, oil, or foreign material adhering
to the application and mating surfaces.
2. Install the carrier cover to the gear carrier. Tighten the bolts to the specified torque. Refer to DLN-217, "Disassembly and
Assembly".
3. Install the front final drive assembly. Refer to DLN-215,
"Removal and Installation".
CAUTION:
Fill the front final drive assembly with r ecommended differential gear oil. Refer to DLN-209,
"Checking Differential Gear Oil".

7. Remove the front final drive assembly bolts, then remove the
front final drive assembly.
CAUTION:
Support the front final drive assembly while removing using
a suitable jack.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
 Make sure there are no pinched or restricted ar eas on the breather hose caused by folding or bend-
ing when installing it.

FRONT FINAL DRIVE
Backlash
1. Fit a dial indicator to the drive gear face to measure the back-
lash.
 If the backlash is outside of t he specification, adjust each side
bearing adjuster.
CAUTION:
Do not change the side bearing adjusters by different
amounts as it will change the side bearing preload torque.
Companion Flange Runout
1. Rotate companion flange and check for runout on the compan-
ion flange face (inner side of the bolt holes) and companion
flange inner side (socket diameter) using suitable tool.
2. If the runout is outside the runout limit, follow the procedure below to adjust.
a. Rotate the companion flange on the drive pinion by 90 °, 180 ° and 270 ° while checking for the position
where the runout is minimum.
b. If the runout is still outside of the runout limit af ter the companion flange has been rotated on the drive pin-
ion, possible cause could be an assembly malfunction of drive pinion and drive pinion bearing or a mal-
functioning drive pinion bearing.
c. If the runout is still outside of the runout limit after repair of the assembly of drive pinion and drive pinion
bearing or drive pinion bearing, replace the companion flange.
DISASSEMBLY
Differential Assembly
1. Drain the differential gear oil if necessary. Backlash : Refer to
DLN-234, "Inspection and Ad-
justment"
SPD513
If the backlash is greater than specification:
Loosen side bearing adjuster A and tighten side bear-
ing adjuster B by the same amount.
If the backlash is less than specification: Loosen side bearing adjuster B and tighten side bear-
ing adjuster A by the same amount.
