PRECAUTIONS
Revision: 2005 August
2005 Murano
PRECAUTIONS
PFP:00001
Cautions
AES000GQ
●
When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
●
Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
●
After servicing suspension parts, be sure to check wheel alignment.
●
Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

On-Vehicle Inspection and Service
AES000I8
Make sure the mounting conditions (looseness, back lash) of each component and component status (wear,
damage) are normal.
INSPECTION OF SUSPENSION ARM BALL JOINT END PLAY
●
Measure axial end play of the suspension arm ball joint by prying between the suspension arm and axle
with a iron bar or something similar.
CAUTION:
Be careful not to damage ball joint boot.
SHOCK ABSORBER INSPECTION
●
Check shock absorber for oil leakage, damage and replace if necessary.
Wheel Alignment Inspection
AES000I9
DESCRIPTION
●
Measure wheel alignment under unladen conditions. “Unladen conditions” mean that fuel, engine coolant,
and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions.
PRELIMINARY CHECK
1.
Check tires for improper air pressure and wear.
2.
Check road wheels for runout.
3.
Check wheel bearing axial end play.
4.
Check suspension arm ball joint axial end play.
5.
Check shock absorber operation.
6.
Check each mounting point of axle and suspension for looseness and deformation.
7.
Check each link, arm and member for cracks, deformation, and other damage.
8.
Check vehicle posture.
CAMBER INSPECTION
●
Measure camber of both right and left wheels with a suitable
alignment gauge and adjust in accordance with the following
procedures.
If outside the standard value, adjust with adjusting bolt on front lower
link.
NOTE:
After adjusting camber, be sure to check toe-in.

TOE-IN
Measure toe-in using the following procedure. If out of specification,
inspect and replace any damaged or worn rear suspension parts.
WARNING:
●
Always perform the following procedure on a flat surface.
●
Make sure that no person is in front of vehicle before push-
ing it.
1.
Bounce rear of vehicle up and down to stabilize the posture.
2.
Push vehicle straight ahead about 5 m (16 ft).
3.
Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. These are measuring points.
4.
Measure distance “A” (rear side).
5.
Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).
If wheels have rotated more than 180 degrees (1/2 turn), try the
above procedure again from the beginning. Never push vehicle
backward.
6.
Measure distance “B” (front side).
7.
If outside the standard value, adjust with adjusting bolt in rear
lower link.
CAUTION:
Be sure to adjust equally on RH and LH side with adjusting
bolt.
