COIL SPRING AND SHOCK ABSORBERPFP:56210
Removal and InstallationEES0025A
REMOVAL
1. Remove the wheel and tire using power tool.
2. Remove the shock absorber lower bolt using power tool.
3. Remove the three shock absorber upper nuts using power tool.
4. Remove the coil spring and shock absorber assembly.
Turn steering knuckle out to gain enough clearance for
removal.
INSTALLATION
Installation is in the reverse order of removal.
The lower seat step (2) in the shock absorber assembly (1)
faces outside of vehicle.

Tighten all nuts and bolts to specification. Refer to FSU-5, "Com-
ponents" .
When installing wheel and tire, refer to WT-7, "Rotation" .
Disassembly and AssemblyEES0025B
DISASSEMBLY
1. Set the shock absorber in a vise, then loosen (without removing)
the piston rod lock nut as shown.
CAUTION:
Do not remove piston rod lock nut at this time.
2. Compress the spring using tool until the shock absorber mount- ing insulator can be turned by hand.
WARNING:
Make sure that the pawls of the two tools are firmly hooked
on the spring. The spring compressors must be tightened
alternately and evenly so as not to tilt the spring.
3. Remove the piston rod lock nut.
Discard the piston rod lock nut, use a new nut for assembly.

UPPER BALL JOINT AND LOWER BALL JOINTPFP:40110
Removal and InstallationEES0025F
The ball joints are part of the upper and lower links. Refer to FSU-13, "Removal and Installation" (upper link),
FSU-14, "
Removal and Installation" (lower link).
InspectionEES0025G
Check the ball joint for excessive play. Replace the upper or lower link assembly if any of the following
exists:
–Ball joint stud is worn.
–Ball joint is hard to swing.
–Ball joint play in axial directions or end play is excessive.
SWINGING FORCE
NOTE:
Before checking the axial forces and end play, turn the lower ball joint at least 10 revolutions so that the ball
joint is properly broken in.
1. Measure the ball joint swinging force using a suitable tool.
Measure at the cotter pin hole for upper ball joint as shown.
Measure at the groove for lower ball joint as shown.
2. Verify the ball joint swinging force is within specification.
TURNING FORCE
Check the turning torque using a suitable tool.
NOTE:
Before checking the axial forces and end play, turn the lower ball
joint at least 10 revolutions so that the ball joint is properly broken in.
