FUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY
Revision: 2006 January2006 M35/M45
1. Turn ignition switch “ON” (with engine stopped), then check connections for leaks by applying fuel pres-
sure to fuel piping.
2. Start engine and let it idle and make sure there are no fuel leaks at the fuel system connections.
ComponentsNBS005RC
Disassembly and AssemblyNBS005RD
CAUTION:
Sub fuel level sensor unit cannot be disassembled and should be replaced as a unit.
DISASSEMBLY
Remove fuel level sensor unit as follows.
1. Disconnect harness connector.
Hold connector by fingers and pull it out, because there is no
stopper release tab.
2. Using suitable tool, pull up tabs points as shown in the figure
(two points) to release the lock.
CAUTION:
Be careful not to damage it.
3. After fixing tabs are disengaged, slide fuel level sensor unit out
in direction shown by the arrow.
CAUTION:
Do not disassemble fuel filter and fuel pump assembly.

When installing rubber bushings, the final tightening must be carried out under unladen conditions with
tires on ground. Oil might 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.
Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

COIL SPRING AND SHOCK ABSORBER
Revision: 2006 January2006 M35/M45
2. Using a spring compressor (commercial service tool), compress
coil spring between rubber seat and spring lower seat (on shock
absorber) until coil spring with a spring compressor is free.
CAUTION:
Be sure a spring compressor is securely attached coil
spring. Compress coil spring
3. Make sure coil spring with a spring compressor between rubber
seat and spring lower seat (shock absorber) is free and then
remove piston rod lock nut while securing the piston rod tip so
that piston rod does not turn.
4. Remove shock absorber mounting bracket, rubber seat, bound
bumper from shock absorber.
5. Remove coil spring with a spring compressor, and then gradually release a spring compressor.
CAUTION:
Loosen while making sure coil spring attachment position does not move.
6. Remove the strut attachment from shock absorber.
INSPECTION AFTER DISASSEMBLY
Shock Absorber Inspection
Check the following:
Shock absorber for deformation, cracks or damage, and replace it if a malfunction is detected.
Piston rod for damage, uneven wear or distortion, and replace it if a malfunction is detected.
For oil leakage, and replace it if a malfunction is detected.
Shock Absorber Mounting Bracket and Rubber Parts Inspection
Check shock absorber mounting bracket for cracks and rubber parts for wear. Replace it if a malfunction is
detected.
Coil Spring Inspection
Check coil spring for cracks, wear or damage, and replace it if a malfunction is detected.
ASSEMBLY
CAUTION:
Do not damage shock absorber piston rod when installing components to shock absorber.
1. Install strut attachment [SST] to shock absorber and secure it in
a vise.
CAUTION:
When installing the strut attachment to shock absorber,
wrap a shop cloth around strut to protect it from damage.
2. Compress coil spring using a spring compressor (commercial
service tool), and install it onto shock absorber.

CAUTION:
Install coil spring as shown in the figure with large diame-
ter side [100 mm (3.94 in)] up and small diameter side [90
mm (3.54 in)] down. (Distinction marks are 4.75 and 5.75
turn from the lower side end.)
Be sure a spring compress or is securely attached to coil
spring. Compress coil spring.
3. Apply soapy water to bound bumper. Insert bound bumper into
shock absorber mounting bracket, and then install it to shock
absorber together with rubber seat.
CAUTION:
Do not use machine oil.
Install shock absorber mounting bracket as shown in the fig-
ure.
CAUTION:
Coil spring is securely seated in spring mounting groove
of rubber seat.
The bottom part of spring should be at the position of A
point of spring seat.
4. Secure piston rod tip so that piston rod does not turn, then
tighten piston rod lock nut with specified torque.
5. Gradually release a spring compressor, and remove coil spring.
CAUTION:
Loosen while making sure coil spring attachment position
does not move.
6. Remove the strut attachment from shock absorber.
