Warning:

To avoid risk of death or severe personal injury:

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.

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

Remove the differential side oil seal. Refer to Removal and Installation.

If necessary, remove the support bearing bracket bolts and the support bearing bracket.

Inspect the components. Refer to Inspection (RH).

INSPECTION AFTER REMOVAL

• Move joint up/down, left/right, and in axial direction. Check for any rough movement or significant looseness.

• Check boot for cracks or other damage, and for grease leakage.

  

• If damaged, disassemble drive shaft to verify damage, and repair or replace as necessary.

INSTALLATION

Installation is in the reverse order of removal.

TRANSAXLE SIDE

• Install a new differential side oil seal. Refer to Removal and Installation.

  CAUTION:

  Do not reuse the differential side oil seal.

       48.0 N·m (4.9 kg−m, 35 ft−lb)

    2. Install the support bearing bracket plate (2) with the notch (A) upward. Tighten the support bearing bracket plate bolts in 2 stages in the order of 7 to 10 as shown.

       CAUTION:

       Do not reuse the support bearing bracket plate.

       Support bearing bracket plate bolt torque

       21.0 N·m (2.1 kg−m, 15 ft−lb)

• MT

  • When installing the support bearing bracket (1), note the following:

    

    1. Tighten the support bearing bracket bolts in 2 stages in the order of 1 to 6 as shown.

       Support bearing bracket bolt torque

       48.0 N·m (4.9 kg−m, 35 ft−lb)

    2. Install the support bearing bracket plate (2) with the notch (A) upward. Tighten the support bearing bracket plate bolts in 2 stages in the order of 7 to 10 as shown.

       CAUTION:

       Do not reuse the support bearing bracket plate.

       Support bearing bracket plate bolt torque

       21.0 N·m (2.1 kg−m, 15 ft−lb)

• Place Tool (A) onto the differential side oil seal to prevent damage to the oil seal while inserting the drive shaft. Slide drive shaft sliding joint and tap with a hammer to install securely.

  

  Tool (A) number

  : KV38107900 (NI-52469-1)

  Warning:

  Ensure that the circular clip is properly engaged, otherwise the joint sub-assembly could pull away from the transaxle during Nissan Sentra vehicle operation resulting in loss of drive force and possible drive shaft damage, which may cause a crash and serious injury or damage to the drive shaft.

  • To ensure the circular clip is properly engaged, grasp the housing (1) and pull back and forth in axial direction while listening for clicking sounds.

    

  • Pull the joint sub-assembly in the axial direction away from transaxle. Confirm that the joint sub assembly cannot be pulled out.

• For MT models, refill the M/T oil. Refer to Refilling.

• Complete the inspection. Refer to Inspection (RH).

WHEEL HUB SIDE

• 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.

• Apply a moderate coat of paste [service parts (440037S000)] to bearing surface (A) as shown.

  Note:

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

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

  

  Wheel hub lock nut

  165 N·m (17 kg−m, 122 ft−lb)

  CAUTION:

  • Do not reuse the wheel hub lock nut.

  • 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 ( — )

• Using hammer (A) and cold chisel (B) stake the wheel hub lock nut (C) as shown.

  

  Warning:

  To avoid the risk of death or severe personal injury:

  • Use the following range when staking the wheel hub lock nut.

    

  (A)	: 6.2 mm (0.244 in)
  (B)	: 26.4 - 27.8 mm (1.039 - 1.094 in)
