NOTE:

• When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

• Before replacing electric controlled coupling due to vibration and/or noise when making low speed turns, refer to TSB to assist in proper diagnosis.

DISASSEMBLY

Remove stud bolts .

Remove electric controlled coupling assembly from final drive assembly.

Remove wave spring.

Remove drive pinion oil seal from the inside of gear carrier. Refer to Disassembly and Assembly.

CAUTION:

When removing electric controlled coupling, replace drive pinion oil seal.

Remove connector bracket from electric controlled coupling.

Separate connector clip from connector bracket.

ASSEMBLY

Install connector bracket to electric controlled coupling.

• For tightening torque, refer to Exploded View.

Join AWD solenoid harness with connector clip.

Install drive pinion oil seal to the inside of gear carrier. Refer to Disassembly and Assembly.

CAUTION:

When removing electric controlled coupling, replace drive pinion oil seal.

Install wave spring to the inside of gear carrier.

Apply liquid gasket to mating surface of electric controlled coupling assembly.

• For applying liquid gasket, refer to Exploded View.

CAUTION:

• Remove old gasket adhering to the mounting surfaces. Also remove any moisture, oil, or foreign material adhering to the mounting surfaces.

• The width of sealant bead is approximately 3 mm (0.12 in). Apply sealant evenly.

Match electric controlled coupling assembly to spline of drive pinion, then install it to final drive assembly .

CAUTION:

Be careful not to damage drive pinion oil seal.

Temporarily tighten reamer bolts to the positions shown in the figure.

Tighten reamer bolts and electric controlled coupling assembly mounting bolts to the specified torque.

• For tightening torque, refer to Exploded View.

Install stud bolts .

: Electric controlled coupling side

CAUTION:

• Do not reuse stud bolt.

• Screw long thread side of stud bolt to electric controlled coupling.

• Screw the stud bolt until the stop by applying a torque of 15 N·m (1.5 kg-m, 11 ft-lb) ±20%.

• After installing stud bolt, the length of the protrusion from electric controlled coupling must be 19.8 mm (0.780 in) ±1.4 mm (0.055 in).
