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.

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 compressor 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.

REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove undercover with a power tool.
3. Remove the mounting nut on the upper side of stabilizer connecting rod with a power tool, and then
remove stabilizer connecting rod from transverse link.
4. Remove the mounting nut and bolt on the lower side of shock absorber arm with a power tool, and then
remove shock absorber arm from transverse link.
5. Remove front cross bar. Refer to FSU-26, "
Components" .
6. Remove transverse link from steering knuckle. Refer to FAX-5, "
Removal and Installation" .
7. Remove mounting nuts and bolts, and then remove transverse link from vehicle.
INSPECTION AFTER REMOVAL
Visual Inspection
Check the following:

Transverse link and bushing for deformation, cracks or damage. Replace it if a malfunction is detected.

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 cotter pin mounting hole. Confirm
spring balance measurement value is within specifications when
ball stud begins moving.

If it is outside the specified range, replace transverse link
assembly.
Rotating Torque Inspection

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 transverse 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 transverse link assembly.Swing torque
