 Tighten main muffler mounting bracket bolts in numerical order as
shown in the figure.
CAUTION:
 Always replace exhaust tube gasket s with new ones when reassembling.
 If heat insulator is badly deformed, repair or repl ace it. If deposits such as mud pile up on the heat
insulator, remove them.
 When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.
 Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.
 Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehicle
side. Check each part for unusual interference, an d then tighten them to the specified torque.
 When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left
directions.
INSPECTION AFTER INSTALLATION
 Make sure clearance between tail tube and bumper is even.
 With engine running, check exhaust tube joints for gas leakage and unusual noises.
 Check to ensure that mounting brackets and mount ing rubbers are installed properly and free from undue
stress. Improper installation could resu lt in excessive noise and vibration.

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,
assemble shaft with circular clip onto joint sub-assembly.
NOTE:
Drive joint inserter (suitable tool) is recommended when install-
ing circular clip.
18. Install joint sub-assembly to shaft using plastic hammer. CAUTION:
Confirm that joint sub-assembly is correctly engaged while
rotating drive shaft.
19. Apply the balance of the spec ified amount of grease (NISSAN
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.
21. 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 screwdriv er into inside of the boot from
the large diameter side of the boot and discharging the inside
air.
