On-Vehicle Inspection and Service

EDS000WN

Check that the mounting conditions (looseness, back lash) of each component and component status (wear,
damage) are normal.

WHEEL BEARING INSPECTION

●

Move wheel hub in the axial direction by hand. Check that there is no looseness of wheel bearings.

●

Rotate wheel hub and check that there is no unusual noise or other irregular conditions. If there are any
irregular conditions, replace wheel bearings.

Removal and Installation

EDS000WO

REMOVAL

1.

Remove tire with power tool.

2.

Remove cotter pin. Then remove lock nut from drive shaft.

3.

joint boot.

CAUTION:

To prevent damage to threads and to prevent ball joint remover (suitable tool) from coming off,
and temporarily tighten mounting nut.

INSPECTION AFTER REMOVAL
Ball Joint Inspection

●

Check for boot breakage, axial looseness, and torque of suspension arm ball joint. Refer to 

RSU-11,

"SUSPENSION ARM"

 .

INSTALLATION

●

Refer to 

RAX-5, "Removal and Installation"
