10. Press side bearing inner races to differential case, using the drift and the base.
CAUTION:
Never reuse side bearing inner race.
11. Press-fit side bearing outer race into side retainer with the drift and the drift bar.
CAUTION:
 At first, using a hammer, tap bearing outer race until itbecomes flat to side retainer.
 Never reuse side bearing outer race.
12. Press-fit side bearing outer race into gear carrier with the drift and the drift bar.
CAUTION:
 At first, using a hammer, tap bearing outer race until itbecomes flat to gear carrier.
 Never reuse side bearing outer race.
13. Place the differential case assembly into gear carrier.
14. Measure side bearing preload. If necessary, select the appropri-
ate side bearing adjusting shim. Refer to "Side Bearing Pre-
load".

COIL SPRING AND STRUT
Make sure piston rod on strut is not damaged when attaching components to strut.
1. Install strut attachment (SST) to strut and fix it in a vise.CAUTION:
When installing strut attachment (SST) to strut, wrap a shop
cloth around strut to protect it from damage.
2. Compress coil spring using a spring compressor (c ommercial service tool), and install it onto strut.
CAUTION:
 Face tube side of coil spri ng downward. Align lower end
to spring rubber seat as shown in the figure.
 Be sure spring compressor (commercial service tool) is securely attached to coil sp ring. Compress coil spring.
3. Apply soapy water to bound bumper and insert into mounting insulator.
CAUTION:
Do not use machine oil.
4. Install mounting insulator bracket, mounting bearing, bound bumper, spring upper seat, spring upper rubber seat and spring
lower rubber seat.
 Installation position of spring upper seat is as shown in the fig-ure.
5. Fix mounting insulator, then tighten piston rod lock nut with specified torque.
CAUTION:
Be careful not to deform mounting insulator bracket.
6. Gradually release spring compressor (commercial service tool), and remove coil spring.
CAUTION:
Loosen spring compressor whil e making sure coil spring
attachment position does not move.
7. Remove strut attachment (SST) from strut.

REMOVAL
1. Remove tire from vehicle with power tool.
2. Remove undercover with power tool.
3. Remove front cross bar.
4. Remove cotter pin at transve rse link, then loosen mounting nut.
5. Use a ball joint remover (SST) to remove transverse link from steering knuckle. Be careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to
threads and to prevent ball jo int remover (SST) from com-
ing off.
6. Remove mounting bolts which are at the back of transverse link (mounting part with body) with power tool, separate transverse
link.
7. Remove mounting bolts which are at the front of transverse link (mounting part with front suspension member) with power tool,
separate transverse link.

INSPECTION AFTER REMOVAL
Visual Inspection
 Check transverse 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 condi-
tion 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 measure- ment value is within the specifications when ball stud begins mov-
ing.
 If it is outside the specified range, replace transverse link assem- bly.
