1. Tilt up glass lid.
2. After loosening glass lid TORX bolts (T25) (left and right), tilt
down glass lid.
3. Adjust glass lid from outside of vehicle so it resembles “A–A” “B–
B” “C–C” as shown in the figure to the right.
4. To prevent glass lid from moving after adjustment, first tighten
the TORX bolts (T25) of front left, and then tighten the TORX
bolts (T25) of rear right.
5. Tighten remaining TORX bolts (T25), being careful to prevent
glass lid from moving.
6. Tilt glass lid up and down several times to make sure it moves
smoothly.
Removal and InstallationAIS003BS

After any adjustment, check sunroof operation and glass lid alignment.

Handle finisher plate and glass lid with care so as not to cause damage.

It is desirable for easy installation to mark each point before removal.
CAUTION:

Always work with a helper.

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
PRECAUTIONSPFP:00001
CautionsAES000MF

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 means 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.

REAR SUSPENSION ASSEMBLYPFP:55020
On-Vehicle Inspection and ServiceAES000MJ
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 by installing and moving up/down between suspension arm and axle with an iron pry
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 InspectionAES000MK
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 part 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 align-
ment gauge and adjust in accordance with the following procedures.
If outside the standard value, adjust with adjusting bolt in front lower
link.
NOTE:
After adjusting camber, be sure to check toe-in.Axial end play : 0 mm (0 in)
Camber : Refer to RSU-18, "
Wheel Alignment" .

TOE-IN
Measure toe-in using following procedure. If out of the specification, inspect and replace any damaged or worn
rear suspension parts.
WARNING:

Always perform 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.
