Using lock nut chisel [SST: KV40108800 (NI-52982)] (A), release stacked area of wheel hub lock nut.

CAUTION:

• Completely release the caulking part of the wheel hub lock nut.

• Never add damage to the driveshaft side screw thread with wheel hub lock nut.

NOTE:

Stacked area is about (A) of the wheel hub lock nut should be widened 34 mm (1.34 in) or more.

Loosen wheel hub lock nut, using a hub lock nut wrench [SST: KV40104001 (NI-53385)] (A).

CAUTION:

• Never use a power tool.

• When rotation of locknut does not turn smoothly, release stacked area is performed again.

Patch wheel hub lock nut with a piece of wood. Hammer the wood to disengage wheel hub from drive shaft.

CAUTION:

• Never place drive shaft joint at an extreme angle.

• Also be careful not to overextend slide joint.

• Never allow drive shaft to hang down without support for joint sub-assembly, shaft and the other parts.

NOTE:

Use suitable puller, if wheel hub and drive shaft cannot be separated even after performing the above procedure.

Remove wheel hub lock nut.

Remove steering outer socket. Refer to Removal and Installation.

Set suitable jack under lower link.

Remove wheel hub and bearing assembly, and then remove splash guard and baffle.

Separate upper link from steering knuckle.

INSTALLATION

Note the following, and install in the reverse order of the removal.

Hub Bolts

Place a suitable washer as shown in the figure to install the hub bolts by using the tightening force of the nut .

CAUTION:

• Check that there is no clearance between wheel hub, and hub bolt.

• Never reuse hub bolt.

Drive shaft

• Clean the matching surface of wheel hub lock nut and wheel hub.

  CAUTION:

  Never apply lubricating oil to these matching surface.

• Clean the matching surface of drive shaft, wheel hub, and wheel bearing. And then apply paste [service parts (440037S000)] to surface of joint sub-assembly of drive shaft.

  

  CAUTION:

  Apply paste to cover entire flat surface of joint sub-assembly of drive shaft.

  Amount paste

  1.0 – 3.0 g (0.04 – 0.10 oz)

• When installing drive shaft to wheel hub.

  CAUTION:

  Never overlap drive shaft stacked area and hub bolts .

  

• Use the following torque range for tightening the wheel hub lock nut.

  : 218 - 223 N·m (22 - 23 kg-m, 161 - 164 ft-lb)

  CAUTION:

  • Since the drive shaft is assembled by press-fitting, use the tightening torque range for the wheel hub lock nut.

  • Be sure to use torque wrench to tighten the wheel hub lock nut. Never use a power tool.

  • Never reuse wheel hub lock nut.

  NOTE:

  Wheel hub lock nut tightening torque does not over torque for avoiding axle noise, and does not less than torque for avoiding looseness.

• Using lock nut crimp punch [SST: KV40108700 ( − )] (A), stake wheel hub lock nut and drive shaft staked area.

  

  NOTE:

  Use the following range for stacking the wheel hub lock nut .

  

  A	: 6.2 mm (0.244 in)
  B	: 29.4 - 30.8 mm (1.157 - 1.213 in)

• Never drop disc rotor.

Inspection

INSPECTION AFTER REMOVAL

Check the following items, and replace the part if necessary.

Ball Joint Inspection

Check boots of upper link, lower link and steering outer socket ball joint for breakage, axial play, and swing torque:

• Upper link: Refer to Inspection.

• Lower link: Refer to Inspection.

• Steering outer socket ball joint: Refer to Inspection.

INSPECTION AFTER INSTALLATION

Check runout of disc rotor, when replaced the disc rotor. Refer to Inspection and Adjustment.

Check wheel sensor harness for proper connection. Refer to Exploded View.

Check the wheel alignment. Refer to Inspection.

Adjust neutral position of steering angle sensor. Refer to Work Procedure.
