Tool number (A): KV40104000 ( — )

8. Using a piece of wood and a suitable tool, tap on the wheel hub lock nut to disengage the drive shaft from the wheel hub and bearing.

CAUTION:

• Do not place the drive shaft joint at an extreme angle.

  Also be careful not to overextend slide joint.

• Do not allow the drive shaft to hang down without support.

NOTE:

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

9. Remove the wheel hub lock nut.
10. Remove the bolts and the wheel hub and bearing from the steering knuckle.
11. Remove the splash guard from the steering knuckle.
12. Suspend the drive shaft with suitable wire.
13. If necessary, remove the wheel studs (1) from the wheel hub and bearing using a suitable tool (A).

CAUTION:

• Remove the wheel studs only when necessary.

• Do not hammer the wheel studs or damage to the wheel hub and bearing may occur.

• Pull out the wheel studs in a direction perpendicular to the wheel hub and bearing.

14. Inspect the components. Refer to FAX-10, "Inspection".

INSTALLATION

Installation is in the reverse order of removal.

CAUTION:

• Do not reuse the wheel stud.

• Do not reuse the cotter pin.

• Place a washer (A) as shown to install the wheel studs (1) by using the tightening force of the nut (B).

CAUTION:

Check that there is no clearance between the wheel stud and the wheel hub and bearing.

• Clean the mating surfaces of the wheel hub lock nut and the wheel hub and bearing.

CAUTION:

• Do not apply lubricating oil to these mating surfaces.

• Clean the mating surfaces of the joint sub-assembly and the wheel hub and bearing. Apply Molykote M77 lubricant to the surface (A) of the joint sub-assembly.

CAUTION:

Apply lubricant to cover the entire flat mating surface of the joint sub-assembly.

NOTE:

Always check with the Parts Department for the latest parts information.

Amount of lubricant : Refer to FAX-49, "Drive Shaft"

• Hold the wheel hub and bearing using Tool. Tighten the wheel hub lock nut.

CAUTION:

• Since the drive shaft is assembled by press-fitting, use a torque wrench to tighten the wheel hub lock nut. Do not use a power tool.

• Too much torque causes axle noise. Too little torque causes wheel bearing looseness. Tighten the wheel hub lock nut to the specification.

Tool number : KV40104000 ( — )

• When installing a the cotter pin (1) and the nut retainer (2), securely bend the cotter pin to prevent rattles.
