COIL SPRING AND SHOCK ABSORBER
Revision: 2007 April2007 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.

Ball joint boot for cracks or other damage, and also for grease leakage. Replace it if a malfunction is
detected.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measurement, move ball stud at least ten times by hand to check for smooth movement.

Hook a spring balance at cutout on ball stud. Confirm spring bal-
ance measurement value is within specifications when ball stud
begins moving.

If it is outside the specified range, replace upper link assembly.

Attach mounting nut to ball stud. Make sure that rotating torque
is within specifications with a preload gauge [SST].

If it is outside the specified range, replace upper link assembly.
Axial End Play Inspection

Move tip of ball stud in axial direction to check for looseness.

If it is outside the specified range, replace upper link assembly.
INSTALLATION

Installation is the reverse order of removal. For tightening torque, refer to FSU-26, "Components" .

Perform final tightening of bolts and nuts at the vehicle installation position (rubber bushing) under
unladen conditions with tires on level ground. Check wheel alignment. Refer to FSU-24, "
Wheel Align-
ment Inspection" . Swing torque

To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.

Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.

Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.

Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.

Replace inner and outer races of tapered roller bearings and needle bearings as a set.

Arrange the disassembled parts in accordance with their assembled locations and sequence.

Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.

After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

Use only the fluids and lubricants specified in this manual.

Use approved bonding agent, sealants or their equivalents when required.

Use hand tools, power tools (disassembly only) and recom-
mended special tools where specified for safe and efficient ser-
vice repairs.

When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.

Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precautions for Three Way CatalystNAS0009G
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.

Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.

When checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary.

Control Units and Electrical PartsNAS0008Y
PRECAUTIONS

Never reverse polarity of battery terminals.

Install only parts specified for a vehicle.

Before replacing the control unit, check the input and output and functions of the component parts.

Do not apply excessive force when disconnecting a connector.

Do not apply excessive shock to the control unit by dropping or
hitting it.

Be careful to prevent condensation in the control unit due to
rapid temperature changes and do not let water or rain get on it.
If water is found in the control unit, dry it fully and then install it in
the vehicle.

Be careful not to let oil to get on the control unit connector.

Avoid cleaning the control unit with volatile oil.

Do not disassemble the control unit, and do not remove the
upper and lower covers.

When using a DMM, be careful not to let test probes get close to
each other to prevent the power transistor in the control unit
from damaging battery voltage because of short circuiting.

When checking input and output signals of the control unit, use
the specified check adapter.

Check FilamentNIS0022Y
1. When measuring voltage, wrap tin foil around the top of the neg-
ative probe. Then press the foil against the wire with your finger.
2. Attach probe circuit tester (in Volt range) to middle portion of
each filament.
3. If a filament is burned out, circuit tester registers 0 or battery
voltage.
4. To locate burned out point, move probe to left and right along fil-
ament. Test needle will swing abruptly when probe passes the
point.
