Removal and Installation


REMOVAL

1.Remove rear drive shaft. Removal And Installation.





2.Disconnect sub-harness connector (1).
3.Remove propeller shaft assembly. Removal And Installation.
4.Support rear final drive assembly with a suitable jack.





5.Remove rear final drive mounting bolt (black arrow) at rear suspension member.





6.Remove final drive mounting bolts and nuts (black arrow) with power tool.
7.Lower rear final drive assembly to the position where electric controlled coupling connector can be disconnect.

CAUTION:
Secure final drive assembly to a suitable jack while removing it.





8.Disconnect electric controlled coupling connector (1) from subharness (2).





9.Remove electric controlled coupling connector from final drive assembly.





10.Remove electric controlled coupling from final drive assembly.
11.Remove sub-harness from final drive assembly.

CAUTION:
- Remove sub-harness only when necessary.
- Never damage side oil seal.

INSTALLATION

1.If remove sub-harness, replace band clip to sub-harness, and then install sub-harness to rear final drive assembly.

CAUTION:
- Never reuse band clip.
- Check original mounting dimensions to install clip to the original position.





- Pin (A) of sub-harness connector clip must be functioning certainly as baffle pin.
- Check the area around the rotating object to see that there is no interference.






2.Apply liquid gasket (1) to mating surface of coupling cover.
- Use Genuine Silicone RTV or equivalent. Recommended Chemical Products And Sealants.

CAUTION:
- Remove old gasket adhering to the mounting surfaces.
Also remove any moisture, oil, or foreign material adhering to the mounting surfaces.
- Overlap both ends of the bead for at least 3 mm (0.12 in).
- Apply liquid gasket to grommet as well.
- The width of sealant bend is approximately 3 mm (0.012
in).





- Never allow liquid gasket to contact the unit characteristics (A) of the coupling cover.





3.Install electric controlled coupling (1) to spline of center stem with grommet of harness facing upward, temporarily tighten reamer bolts (2) to the positions shown in the figure.






CAUTION:
Never damage side oil seal.
4.Tighten reamer bolts and coupling cover mounting bolts to the specified torque.

CAUTION:
Never allow harness to get caught in the bolt.





5.Replace connector clip from electric controlled coupling connector, and then insert it to final drive assembly.

CAUTION:
- Never reuse connector clip.
- When inserting connector clip to final drive assembly, never tug harness.





6.Connect electric controlled coupling connector (1) to sub-harness (2).
7.Install rear drive shaft. Removal And Installation.

CAUTION:
Never damage electric controlled coupling oil seal.
8.Install propeller shaft assembly. Removal And Installation.
9.When oil leaks while removing, check oil level after the installation. Inspection.
10.When replacing electric controlled coupling, perform writing unit characteristics after installing rear final drive assembly to the vehicle. Work Procedure.

CAUTION:
Always writing unit characteristics of both side electric controlled couplings.
