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)" .

UPPER LINKPFP:54524
Removal and InstallationNES0000C
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove undercover with power tool.
3. Remove shock absorber. Refer to FSU-10, "
COIL SPRING AND SHOCK ABSORBER" .
4. Remove cotter pin of upper link ball joint, then loosen mounting nut.
5. 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.
6. Remove bolts holding upper link to body with power tool.
7. Remove upper link from vehicle.
INSPECTION AFTER REMOVAL
Visual Inspection

Check upper link and bushing for deformation, cracks, or damage. If any non-standard condition is found,
replace it.

Check boot of ball joint for cracks, or other damage, and also for grease leakage. If any non-standard con-
dition is found, replace it.
Ball Joint Inspection

Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measurement, move ball joint at least ten times by hand to check for smooth movement.

Hook spring balance at ball stud. Confirm spring balance mea-
surement value is within the specifications when ball stud begins
moving.

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

Attach mounting nut to ball stud. Check that rotating torque is
within specifications with a preload gauge.

If it is outside the specified range, replace upper link assembly.Swing torque:
Less than 2.0 N·m (0.20 kg-m, 18 in-lb)
Measured value of spring balance:
Less than 34.8 N (3.5 kg, 7.8 lb)
