ii. Since front timing chain case is offset for difference of bolt holes,
tighten bolts temporarily with holding front timing chain case
from front and top as shown in the figure.
For bolt length and positions, refer to the step e.
iii. Same as the step ii, insert dowel pin with holding front timing
chain case from front and top completely.
e. Tighten mounting bolts to the specified torque in numerical order
as shown in the figure.
There are two type of mounting bolts. Refer to the following
for locating bolts.
f. After all bolts tightened, retighten them to the specified torque in
numerical order as shown in the figure.
6. Install two mounting bolts in front of oil pan (upper) in numerical
order as shown in figure.
7. Install oil pan (lower). Refer to EM-29, "
OIL PAN AND OIL STRAINER" .
8. Install intake valve timing control covers as follows:
a. Install new seal rings in shaft grooves.
b. Apply a continuous bead of liquid gasket with the tube presser
[SST: WS39930000 ( — )] to intake valve timing control cov-
ers as shown in the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "

14. Screw a drive shaft puller (suitable tool) 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 slid-
ing hammer (suitable tool) 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 from shaft.
16. Remove boot from shaft.
17. Clean the old grease on joint sub-assembly with paper towels.
18. Apply the specified amount of grease (NISSAN genuine grease
or equivalent) inside joint sub-assembly serration hole until
grease begins to ooze from ball groove and serration hole. After
applying grease, use a shop cloth to wipe off old grease that has
oozed out.
19. Wrap serration on shaft with tape to protect the boot from dam-
age. Install new boot and boot bands to shaft.
20. Remove the tape wrapped around the serration on shaft.
21. Position circular clip on groove at the shaft edge. Align both
counter axles of the shaft edge and joint sub-assembly. Then,
assemble shaft with circular clip onto joint sub-assembly.
NOTE:
Drive joint inserter (suitable tool) is recommended when install-
ing circular clip.

22. Install joint sub-assembly to shaft using plastic hammer.
CAUTION:
Confirm that joint sub-assembly is correctly engaged while
rotating drive shaft.
23. Apply the balance of the specified amount of grease (NISSAN
genuine grease or equivalent) into the boot inside from large
diameter side of boot.
24. 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 and joint sub-assembly, boot may come
off. Remove all grease from the surface.
25. To prevent from the deformation of the boot, adjust the boot
installation length to the specified value shown below (L) by
inserting the flat-bladed screwdriver into inside of the boot from
the large diameter side of the boot and discharging the inside
air.
CAUTION:
If the boot mounting length is outside the standard, it may cause breakage in the boot.
Be careful not to touch the inside of the boot with a tip of a flat-bladed screwdriver.
26. Secure the large and small ends of the boot with new boot
bands using the boot band crimping tool [SST: KV40107300
( – )] as shown in the figure.
NOTE:
Secure boot band so that dimension “M” meets the specification
as shown.
27. Secure joint sub-assembly and shaft, and then make sure that
they are in the correct position when rotating boot. Install them
with new boot band when boot installation positions become
incorrect.
28. Insert drive shaft to wheel hub and bearing assembly, and then
temporarily tighten hub lock nut.
29. Install transverse to steering knuckle. Refer to FAX-5, "
COMPO-
NENT" .
30. Install steering outer socket to steering knuckle. Refer to FA X - 5 , "
COMPONENT" .
31. Install disc rotor. Refer to FA X - 5 , "
Removal and Installation" .
32. Install torque menber fixing bolts to steering knuckle. Refer to BR-23, "
FRONT DISC BRAKE" .
33. Install brake hose bracket to steering knuckle. Refer to BR-12, "
