Replacement


WHEEL SIDE

1.Remove tires with power tool.
2.Remove wheel sensor from steering knuckle. Exploded View.

CAUTION:
Never pull on wheel sensor harness.
3.Remove brake hose bracket. Exploded View.
4.Remove caliper assembly. Hang caliper assembly a place where it will not interfere with work. Refer to
Exploded View (1 piston type), Exploded View (4 piston type).

CAUTION:
Never depress brake pedal while brake caliper is removed.
5.Remove disc rotor. Removal and Installation (1 piston type), Exploded View (4 piston type).
6.Remove cotter pin, then loosen wheel hub lock nut with a power tool.
7.Patch wheel hub lock nut with a piece of wood. Hammer the wood to disengage wheel hub and bearing assembly from drive shaft. Take out the wheel hub lock nut.

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 housing (or joint sub-assembly), shaft and the other parts.
NOTE:
Use a suitable puller if wheel hub and bearing assembly and drive shaft cannot be separated even after performing the above procedure.





8.Remove cotter pin (1) of steering outer socket, and then loosen the nut.
9.Remove steering outer socket (2) from steering knuckle (3) so as not to damage ball joint boot (4) using the ball joint remover.

CAUTION:
Temporarily tighten the nut to prevent damage to threads and to prevent the ball joint remover from suddenly coming off.
10.Remove cotter pin of transverse link and steering knuckle, and then loosen nut.
11.Separate transverse link from steering knuckle so as not to damage ball joint boot using the ball joint remover.

CAUTION:
Temporarily tighten the nut to prevent damage to threads and to prevent the ball joint remover from suddenly coming off.
12.Remove drive shaft from wheel hub and bearing assembly.
13.Remove boot bands, and then remove boot from joint sub-assembly.





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

CAUTION:
- Align a sliding hammer and drive shaft and remove them by pulling firmly and uniformly.
- If joint sub-assembly cannot be pulled out, try after removing drive shaft from vehicle.





15.Remove the circular clip (1) from shaft.
16.Remove boot from shaft.
17.Clean the old grease on joint sub-assembly with paper waste.
18.Fill serration slot joint sub-assembly with NISSAN genuine grease or equivalent until the serration slot and ball groove become full to the brim.

CAUTION:
After applying grease, use a paper waste to wipe off old grease that has oozed out.
19.Install boot and boot bands to shaft.

CAUTION:
- Wrap serration on shaft with tape to protect the boot from damage.
- Never reuse boot and boot band.
20.Remove the tape wrapped around the serration on shaft.
21.Position circular clip on groove at the shaft edge.

CAUTION:
Never reuse circular clip.
NOTE:
Drive joint inserter is recommended when installing circular clip.
22.Align both center axles of the shaft edge and joint sub-assembly. Then assemble shaft with circular clip joint sub-assembly.





23.Install joint sub-assembly (1) to shaft using plastic hammer.

CAUTION:
Confirm that joint sub-assembly is correctly engaged while rotating drive shaft.
24.Apply the balance of the specified amount of grease into the boot inside from large diameter side of boot.
Standard


Grease amount: Drive Shaft.





25.Install the boot securely into grooves (indicated by "*" marks)
shown in the figure.

CAUTION:
If grease adheres to the boot mounting surface (with "*"
mark) on the shaft or joint sub-assembly, boot may come off. Remove all grease from the surface.
26.To prevent the deformation of the boot, adjust the boot installation length (L) to the specified value shown below by inserting the suitable tool into inside of the boot from the large diameter side of the boot and discharging the inside air.
Standard


Boots installed : Drive Shaft.
length (L)

CAUTION:
- If the boot installation length is outside the standard, it may cause breakage of boot.
- Be careful not to touch the inside of the boot with a tip of tool.





27.Secure the large and small ends of the boot with boot bands using the boot band crimping tool (A) [SST: KV-40107300 (-)].
NOTE:





Secure boot band so that dimension (M) meets the specification as shown in the figure.
Dimension (M): 2.0 - 3.0 mm (0.079 - 0.118 in)
28.Secure joint sub-assembly and shaft, and then make sure that they are in the correct position when rotating boot. Install them with boot band when boot installation positions become incorrect.
29.Insert drive shaft to wheel hub and bearing assembly, and then temporarily tighten wheel hub lock nut.

CAUTION:
- The drive shaft is press-fit. When assembling the shaft, never press it, but pull it until fully seated by tightening the wheel hub lock nut.
- Check that anticorrosive oil is applied to the thread of the drive shaft. If not, apply appropriate oil such as engine oil.
- If sufficient oil is not applied to the thread of the drive shaft, the wheel hub lock nut may be seized and the tightening torque reaches the specified limit prematurely. It may cause looseness or abnormal noises.
30.Install transverse link to steering knuckle. Exploded View.
31.Install steering outer socket to steering knuckle. Exploded View.
32.Install disc rotor. Removal and Installation (1 piston type), Exploded View (4 piston type).
33.Install caliper assembly to steering knuckle. Exploded View (1 piston type), Exploded View (4 piston type).
34.Install brake hose bracket to steering knuckle. Exploded View.
35.Install wheel sensor to steering knuckle. Exploded View.
36.Tighten the wheel hub lock nut to the specified torque. Exploded View.
37.Install cotter pin.

CAUTION:
- Never reuse cotter pin.
- Bend it at the root sufficiently to prevent any looseness.
