REAR WHEEL HUB AND KNUCKLE
On-Vehicle InspectionINFOID:0000000001327526
Make sure the mounting conditions (looseness, back lash) of each component and component status (wear,
damage) are normal.
WHEEL BEARING INSPECTION
With the vehicle raised, inspect the following.
 Move wheel hub in the axial direction by hand. Che ck that there is no looseness of front wheel bearing.
 Rotate wheel hub and make sure there is no unusual noi se or other irregular conditions. If there are any
irregular conditions, replace wheel hub and bearing assembly.
Removal and InstallationINFOID:0000000001327527
COMPONENTS
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove cotter pin. Then remove lock nut from drive shaft.
3. Remove brake caliper with power tool. Hang it in a place where it will not interfere with work. Refer to BR-
25, "Removal and Installation of Brake Caliper Assembly".

9. Remove parking brake cable and parking brake shoe from back plate. Refer to PB-6 and PB-4.
10. Remove fixing nuts of anchor block with power tool , then remove anchor block and back plate from axle.
11. Loosen fixing bolts and nuts of front lower link, radius rod, and rear lower link in side of suspension mem-
ber.
12. Set jack under rear lower link. Then remove fixing bolt in front lower link side of shock absorber with power tool.
13. Remove bolt and nut in axle side of rear lower link with power tool. Then remove coil spring. Refer to RSU-15
.
14. Remove fixing bolts and nuts in axle side of fr ont lower link, radius rod with power tool.
15. Remove suspension arm and cotter pin at axle, then loosen mounting nut.
16. 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 nu t to prevent damage to threads and to prevent ball joint remover
(suitable tool) from coming off.
17. Remove axle from vehicle.
INSPECTION AFTER REMOVAL
Check for deformity, cracks and damage on each parts, replace if necessary.
Ball Joint Inspection
Check for boot breakage, axial looseness, and tor que of suspension arm ball joint. Refer to RSU-11, "Removal
and Installation".
INSTALLATION
 Refer to "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 conditions
with tires on level ground, Check wheel alignment. Refer to RSU-5, "
Wheel AlignmentInspection".
 After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-8, "
Adjust-
ment of Steering Angle Sensor Neutral Position".
Disassembly and AssemblyINFOID:0000000001327528
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.
