13. Remove fixing bolts and nuts in axle side of front lower link, radius rod with power tool.
14. Remove suspension arm and cotter pin at axle, then loosen mounting nut.
15. Use a ball joint remover (suitable tool) to remove suspension arm from axle. Be careful not to damage ball
joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to threads and to prevent ball joint remover
(suitable tool) from coming off.
16. Remove axle from vehicle.
INSPECTION AFTER REMOVAL
Ball Joint Inspection
Check for boot breakage, axial looseness, and torque of suspension arm ball joint. Refer to RSU-11,
"INSPECTION AFTER REMOVAL" .
INSTALLATION

Refer to RAX-5, "Removal and Installation" 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 installation position of suspension links (rubber bushing) under unladen condi-
tions with tires on level ground, Check wheel alignment. Refer to RSU-5, "
Wheel Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .
Disassembly and AssemblyADS000C6
DISASSEMBLY
Wheel Bearing
CAUTION:
Do not disassemble if wheel bearing has no trouble.
1. Remove wheel bearing fixing bolts and anchor block fixing nuts, and remove wheel hub and bearing
assembly, back plate and anchor block from axle.
2. Using a drift (SST) and a puller (suitable tool), press wheel hub
out to remove from wheel bearing.
