Using hammer (A) and Tool (B) release staked area (C) of wheel hub lock nut (D).

Tool number (B)

: (NI-52982)

Visually verify that staked area (A) of wheel hub lock nut (B) is completely released from front drive shaft (1) or damage to drive shaft can occur.

(C)	: Fully released
(D)	: Not fully released
(E)	: Fully released (sectional view)
(F)	: Not fully released (sectional view)

Warning:

To avoid risk of death or severe personal injury:

• Be sure that staked area of wheel hub lock nut is fully released or damage to drive shaft can occur.

• Do not damage front drive shaft threads.

Hold the wheel hub and bearing using Tool (A). Loosen the wheel hub lock nut.

Tool (A) number

: KV40104000 ( — )

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.

Remove the wheel hub lock nut.

Remove the nut and bolt from the lower ball joint. Disconnect the steering knuckle from the transverse link.

Remove the drive shaft from the wheel hub and bearing.

Remove the boot bands.

Separate the boot from the joint sub-assembly.

Screw a suitable tool (A) into the joint sub-assembly screw part to a length of 30 mm (1.18 in) or more. Support the drive shaft with one hand and pull out the joint sub-assembly from the shaft.

CAUTION:

• Align the suitable tool and the drive shaft. Remove the joint sub-assembly by pulling firmly and uniformly.

• If the joint sub-assembly cannot be pulled out, try after removing the drive shaft from the Nissan Sentra vehicle. Refer to Removal and Installation (LH)or Removal and Installation (RH).

Remove the circular clip (1) from the shaft.

Remove the outer boot from the shaft.

INSTALLATION

Clean the old grease from the joint sub-assembly using paper shop cloths.

Fill the serration slot on the joint sub-assembly (1) with NISSAN Genuine grease or equivalent until the serration slot and ball groove become full to the brim.

CAUTION:

After applying the grease, use paper shop cloths to wipe off the grease that has oozed out.

Note:

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

Install the outer boot and the boot bands to the shaft.

CAUTION:

• Wrap the serration on the shaft with tape to protect the boot from damage.

• Do not reuse the boot.

• Do not reuse the boot bands.

Remove the tape wrapped around the serration on the shaft.

Position the circular clip (1) on the groove at the shaft edge.

CAUTION:

Do not reuse the circular clip.

Note:

A drive joint inserter is recommended when installing the circular clip.

Align with the shaft and the joint sub-assembly. Assemble the shaft with the joint sub-assembly while holding the circular clip.

Install the joint sub-assembly (1) to the shaft using a suitable tool.

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 the drive shaft.

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

Apply the specified amount of grease to the inside of the large diameter side of the boot. Note:

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

Grease amount

: Refer to Drive Shaft.

Install the boot securely into the grooves (indicated by “*” marks) as shown.

CAUTION:

If there is grease on the boot mounting surfaces (indicated by “*” marks) on the shaft or the joint sub-assembly, the boot may come off. Remove all grease from the boot mounting surfaces.

To prevent the deformation of the boot, adjust the boot installation length to the specified value by inserting a suitable tool into the inside of the boot from the large diameter side of the boot and discharging the inside air.

Boot installation length (L)

: Refer to Drive Shaft.

CAUTION:

• The boot may break if the boot installation length is not correct.

• Be careful not to touch the inside of the boot with the tip of the suitable tool.

Install new large and small boot bands securely using Tool (A).

CAUTION:

Do not reuse the boot bands.

Tool number

(A): KV40107300 (NI-51751)

Secure the boot band so that dimension (A) meets the specification.

Dimension (A)

: Refer to Drive Shaft.

Attempt to rotate the boot to check whether or not the boot bands are securing the boot. If the boot is not secure, remove the boot bands, reposition the boot, and install new boot bands.

Clean the mating surfaces of the wheel hub lock nut and the wheel hub assembly.

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.

Install the drive shaft to the wheel hub and bearing. Temporarily install, but do not tighten, the wheel hub lock nut.

CAUTION:

Do not reuse the wheel hub lock nut.

Install the transverse link to the steering knuckle with the nut and bolt. Refer to Exploded View.

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:

• 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.

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

• Do not reuse wheel hub lock nut.

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

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

Tool number

: KV40104000 ( — )

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