Installation of electronically controlled coupling assembly
1. Using a drift, install the coupling front bearing to the electroni-
cally controlled coupling.
CAUTION:
At disassembly, be sure to install shim between electroni-
cally-controlled coupling and bearing. Chamfering side of
shim should be coupled to install.
2. Assemble the electronically controlled coupling assembly to the drive pinion gear.
3. Using a drift, drive an oil seal until it becomes flush with the case
end.
CAUTION:
lOil seals are not reusable. Never reuse them.
lApply multi-purpose grease onto the oil seal lips, and dif-
ferential oil onto the circumference of the oil seal.
4. Apply sealant (Three bond 1217 or the equivalent) around the
carrier case mounting surface on the coupling cover.
CAUTION:
Remove old sealant on the mounting surface, then remove
any moisture, oil, and foreign material from the application
and mounting surfaces.
5. Assemble the coupling cover to the carrier case assembly with
the arrow facing upward, temporarily tighten reamer bolts to the
positions shown in the figure.
6. Tighten the reamer bolts and coupling cover mounting bolts to
the specified torque.
7. Assemble the companion flange.
8. Using a flange wrench, tighten the companion flange nut to the specified torque.
CAUTION:
Do not reuse the companion flange nut.
9. Check companion flange runout. Refer toRFD-16, "
COMPANION FLANGE RUNOUT".

PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEES0007C
lFinal tightening of bushings must be carried out under unladen condition with tires on the ground. Oil will
shorten life of bushings. Be sure to wipe off any spilled oil.
l“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare tire,
jack, and hand tools should be unloaded.
lAfter installing the removed suspension parts, always check wheel alignment and adjust if necessary.
lReplace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.
Precautions for Brake SystemEES000JB
lWhen installing rubber parts, final tightening must be carried out
under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake tubes.
lAfter installing removed suspension parts, check wheel align-
ment and adjust if necessary.
lAlways torque brake lines when installing.
