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.

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).

Item Function
Torque converterThe torque converter is the device that increases the engine torque as well as the con-
ventional AT and transmits it to the transaxle.
Oil pumpThe adoption of a trochoidal oil pump with a flow control valve actuated directly by the
engine enables the sufficient discharge from an oil pump in the low-rpm range and the
adequate discharge adjustments in the high-rpm range.
Planetary gear
Perform the transmission of drive power and the switching of forward/backward move-
ment. Forward clutch
Reverse brake
Primary pulley It is composed of a pair of pulleys (the groove width is changed freely in the axial direc-
tion) and the steel belt (the steel star wheels are placed continuously and the belt is guid-
ed with the multilayer steel rings on both sides). The groove width changes according to
wrapping radius of steel belt and pulley from low status to overdrive status continuously
with non-step. It is controlled with the oil pressures of primary pulley and secondary pul-
ley. Secondary pulley
Steel belt
Output gear
Reduction gear consists of primary deceleration (output gear and idler gear in pair) and
secondary deceleration (reduction gear and final gear in pair). Each of them uses a he-
lical gear. Idler gear
Reduction gear

Differential
Manual shaft
The parking rod rotates the parking pole and the parking pole engages with the parking
gear when the manual shaft is in “P” position. As a result the parking gear and the output
