LEFT SIDE : Removal and InstallationINFOID:0000000003811084
REMOVAL
1. Remove tires.
2. Remove wheel sensor and sensor harness. Refer to BRC-57, "
FRONT WHEEL SENSOR : Exploded
View" (without VDC), BRC-151, "FRONT WHEEL SENSOR : Exploded View" (with VDC).
3. Remove lock plate of brake hose from strut assembly. Refer to BR-19, "
FRONT : Exploded View".
4. Remove caliper assembly. Hang caliper assembly not to interfere with work. Refer to BR-34, "
BRAKE
CALIPER ASSEMBLY : Exploded View".
5. Remove disc rotor. Refer to BR-35, "
BRAKE CALIPER ASSEMBLY : Removal and Installation".
6. Remove cotter pin, and then loosen wheel hub lock nut. Refer to FA X - 8 , "
Exploded View".
7. Patch wheel hub lock nut with a piece of wood. Hammer the
wood to disengage drive shaft from wheel hub and bearing
assembly.
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 and the other parts.
NOTE:
Use suitable puller, if wheel hub and bearing assembly and drive
shaft cannot be separated even after performing the above pro-
cedure.
8. Remove wheel hub lock nut.
9. Remove steering knuckle from strut assembly. Refer to FSU-9, "
Exploded View".
10. Remove drive shaft from wheel hub and bearing assembly.
11. Remove drive shaft from transaxle assembly.
 Use the drive shaft attachment (A) (SST: KV40107500) and a
sliding hammer (B) while inserting tip of the drive shaft attach-
ment between housing assembly and transaxle assembly.
CAUTION:
Never place drive shaft joint at an extreme angle when
removing drive shaft. Also be careful not to overextend
slide joint.
INSTALLATION
Note the following, and install in the reverse order of removal.
 Always replace differential side oil seal with new one when installing drive shaft. Refer to TM-162, "
Exploded
View" (CVT: RE0F09B), TM-325, "Exploded View" (CVT: RE0F10A).
: Wheel side
: Fill NISSAN Genuine grease or equivalent.
Refer to GI-4, "

FRONT DRIVE SHAFT
 Always replace differential side oil seal with new one when installing drive shaft. Refer to TM-162, "Exploded
View" (CVT: RE0F09B), TM-325, "Exploded View" (CVT: RE0F10A).
 Place the protector (A) (SST: KV38107900) onto transaxle assem-
bly to prevent damage to the oil seal while inserting drive shaft.
Slide drive shaft sliding joint and tap with a hammer to install
securely.
 Install support bearing bracket (1) in following proce-
dure.(VQ25DE)
- Temporarily tighten mounting bolts (A), then tighten them to speci-
fied torque.
- Set plate (2) so that notch (C) become upper side.
- Temporarily tighten mounting bolts in the order (a) (b), then tighten
them to specified torque.
 Install support bearing bracket (1) in following proce-
dure.(VQ35DE)
- Temporarily tighten mounting bolts (A), then tighten them to speci-
fied torque.
- Temporarily tighten mounting bolts (B), then tighten them to speci-
fied torque.

WHEEL SIDE : Disassembly and AssemblyINFOID:0000000003811086
DISASSEMBLY
1. Fix shaft with a vise.
CAUTION:
Protect shaft using aluminum or copper plates when fixing with a vise.
2. Remove boot bands, and then remove boot from joint sub-assembly.
3. Screw 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 (VQ25DE) or housing assembly (VQ35DE).
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.
4. Remove circular clip from shaft (VQ25DE) or housing assembly
(VQ35DE).
