On-Vehicle InspectionEDS0005R
Inspect to check that there is no excessive play, cracking, wear, o r
other damage to front axle.
●Turn front wheels (left/right) and check the play.
●Check that no nails or other foreign objects are embedded.
●Retighten all axle nuts and bolts to the specified torque.
FRONT WHEEL BEARINGS
With the vehicle raised, inspect the following.
●Move wheel hub in the axial direction by hand. Check that there is no looseness of front wheel bearings.
●Rotate wheel hub and check that there is no unusual noise or other irregular conditions. If there are any
irregular conditions, replace the wheel bearing.

CAUTION:
●When removing drive shaft from vehicle, be careful to
avoid interfering with brake hose, ABS wheel speed sen-
sor harness, and other parts.
●When removing drive shaft, do not apply an excessive
angle (22° or more) to drive shaft joint. Also be careful
not to excessively extend slide joint.
●Do not lift drive shaft, with axle attached, by grasping
counter shaft only.
●Do not allow drive shaft, with transaxle inserted, to hang down without support for counter
