FRONT SUSPENSION ASSEMBLYPFP:54010
On-Vehicle InspectionNES00005
Make sure the mounting conditions (looseness, back lash) of each component and component statues (wear,
damage) are normal.
INSPECTION OF BALL JOINT END PLAY OF EACH LINK
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Check ball joint axial end play of each link.
CAUTION:
Be careful not to damage ball joint boot.
Upper Link Ball Joint

Measure axial end play by installing and moving up/down with
an iron pry bar or something similar between upper link and
steering knuckle.
Steering Knuckle Lower Ball Joint

Measure axial end play by installing and moving up/down with
an iron pry bar or something similar between steering knuckle
and wheel.
Compression Rod Ball Joint

Measure axial end play by installing and moving up/down with
an iron pry bar or something similar between compression rod
and transverse link.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace if necessary. Refer to FSU-10, "COIL SPRING
AND SHOCK ABSORBER" . Axial end play : 0 mm (0 in)

Removal and InstallationNES00008
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove brake caliper with power tool. Hang it in a place where it will not interfere with work. Refer to BR-
26, "FRONT DISC BRAKE" .
3. Remove undercover with power tool.
4. Remove fixing bolts and nuts, then remove front cross bar from vehicle with power tool.
5. Remove steering hydraulic piping bracket from front suspension member. Refer to PS-33, "
HYDRAULIC
LINE" .
6. Remove steering gear and front suspension member attachment bolts and hang steering gear on vehicle.
Refer to PS-17, "
POWER STEERING GEAR AND LINKAGE" .
7. Set jack under engine.
CAUTION:
When setting jack to engine, use a wooden block or an equivalent for the setting.
8. Remove fixing bolt and nut between shock absorber and transverse link with power tool.
9. Remove cotter pin of upper link ball joint, then loosen mounting nut.
10. Use a ball joint remover (suitable tool) to remove upper link from steering knuckle. Be careful not to dam-
age ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to threads and to prevent ball joint remover
(suitable tool) from coming off.
11. Remove fixing nut and washer located at the bottom of stabilizer connecting rod, and then remove stabi-
lizer connecting rod from transverse link with power tool.
12. Remove fixing nuts between engine mounting insulator and front suspension member. Refer to EM-101,
"ENGINE ASSEMBLY" .
13. Remove fixing nuts between front suspension member and body with power tool.
14. Remove front suspension assembly form vehicle.
INSTALLATION

Refer to FSU-8, "Components" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

Perform final tightening of shock absorber lower side (rubber bushing) under unladen condition with tires
on ground. Check wheel alignment. Refer to FSU-21, "
SERVICE DATA AND SPECIFICATIONS (SDS)" .

CAUTION:
Do not pull on wheel sensor harness.
4. Remove mounting nuts of brake hose from shock absorber.
5. Remove mounting bolt and nut between shock absorber and transverse link with power tool.
6. Remove tower bar. Refer to FSU-20, "
TOWER BAR" .
7. Remove mounting nuts on mounting insulator with power tool, then remove shock absorber from vehicle.
INSTALLATION

Refer to FSU-8, "Components" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

on ground. Check wheel alignment. Refer to FSU-21, "
SERVICE DATA AND SPECIFICATIONS (SDS)" .
Disassembly and AssemblyNES0000A
DISASSEMBLY
NOTE:
Make sure piston rod on shock absorber is not damaged when removing components from shock absorber.
1. Install strut attachment (SST) to shock absorber and fix it in a
vise.
CAUTION:
When installing strut attachment (SST) to shock absorber,
wrap a shop cloth around shock absorber to protect it from
damage.
2. Using a spring compressor (commercial service tool), compress
coil spring between spring upper seat and spring lower seat (on
shock absorber) until coil spring is free.
CAUTION:
Be sure spring compressor (commercial service tool) is
securely attached to coil spring. Compress coil spring.
3. Check that coil spring between spring upper seat and spring
lower seat is free and then secure piston rod tip so that piston
rod does not turn, and remove piston rod lock nut.
4. Remove mounting insulator, bound bumper, spring upper seat.
Then remove coil spring from shock absorber.
5. Gradually release spring compressor (commercial service tool),
and remove coil spring.
CAUTION:
Loosen while making sure coil spring attachment position
does not move.
6. Remove strut attachment (SST) from shock absorber.
