FRONT TIMING CHAIN CASE
 Align notch of front timing chain case with protrusion of oil pan
gasket.
 Apply liquid gasket with the tube presser (commercial service tool) to top surface of oil pan (upper) as shown in the figure.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "
Recommended Chemical Product and Sealant".
c. Install new O-rings on rear timing chain case.
d. Assemble front timing chain case as follows:
i. Fit lower end of front timing chain case tightly onto top face of oil pan (upper). From the fitting point, make entire front timing chain
case contact rear timing chain case completely.
CAUTION:
Be careful that oil pan gasket is in place.
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.

TIMING CHAIN
 Apply liquid gasket on installa
tion position of water pump and cylinder head very completely.
d. Align rear timing chain case and water pump assembly with dowel pins (right and left) on cylinder block and install rear timing chain case.
 Make sure O-rings stay in place during installation to cylinder block and cylinder head.
e. Tighten mounting bolts in numerical order as shown in the fig- ure.
 There are two types mounting bolts. Refer to the following forlocating bolts.
f. After all bolts are tightened, retighten them to the s pecified torque in numerical order shown in the figure.
 If liquid gasket protrudes, wipe it off immediately.
g. After installing rear timing chain case, check the surface height difference between the following parts on the oil pan (upper)
mounting surface.
 If not within the standard, repeat the installation procedure.Bolt length: Bolt position
20 mm (0.79 in) : 1, 2, 3, 6, 7, 8, 9, 10

Replace entire drive shaft assembly when noi se or vibration occur from drive shaft.
DRIVE SHAFT BOOT REPLACEMENT
1. Remove tires from vehicle with power tool.
2. Remove undercover with power tool.
3. Remove cotter pin. Then remove lock nut from drive shaft with power tool.
4. Remove wheel sensor harness fr om strut assembly. Refer to BRC-52
.
CAUTION:
Do not pull on wheel sensor harness.
5. Remove brake hose lock plate. Then remove brake hose from strut assembly. Refer to BR-10
.
6. Remove fixing bolts and nuts between strut assembly and steering knuckle with power tool.
7. Remove drive shaft from wheel hub and bearing assembly.
8. Using a puller (suitable tool), remove drive shaft from steering knuckle.
CAUTION:
When removing drive shaf t, do not apply an excessive
angle to drive shaft joint. Al so be careful not to excessively
extend slide joint.
9. Remove boot bands, and then remove boot from joint sub-assembly.
10. 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.
11. Remove the circular clip from shaft.
12. Remove boot from shaft.
13. Clean the old grease on joint sub-assembly with paper towels.

14. 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.
15. Wrap serration on shaft with tape to protect the boot from dam- age. Install new boot and boot bands to shaft.
16. Remove the tape wrapped around the serration on shaft.
17. Position circular clip on groove at the shaft edge. Align both counter axles of the shaft edge and joint sub-assembly. Then,

genuine grease or equivalent) into the boot inside from large
diameter side of boot.
20. 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.
