BOLT REMOVAL
Make mating marks on the toe control arm’ and eccen tric
cam bolt before removing the bolt.
INSPECTION
lCheck the bushings for wear and deterioration.
l Check the lower arm or toe control arm for bends or
damage.
lCheck bolts for condition and straightness.
BALL JOINT BREAKAWAY TORQUE CHECK
(1) After shaking the ball joint stud several times , install the
nut to the stud and use the special tool to measure the
breakaway torque of the ball joint.
Standard value: Nm
When the measured value exceeds the standard value ,
replace the toe control arm assembly.
(3) When the measured value is lower than the stand ard
value, check that the ball joint turns smoothly wit hout
excessive play. If so, it is possible to use that b all joint.
BALL JOINT DUST COVER CHECK
If there are any cracks in or damage to the dust co ver, replace
the arm assembly.
CONTROL ARM BALL JOINT DUST COVER
REPLACEMENT
Replace the dust cover by the following procedure o nly if
the dust cover has become damaged by accident durin g
servicing.
(1) Remove the dust cover.
(2) Apply multi-purpose grease to the lip and insid e of the
dust cover.
(3) Drive in the dust cover with the special tool u ntil it is

TSB Revision
System check sound When starting the engine, a thudd
ing sound can sometimes be heard coming from inside.the engine compartment, but this is because the system operatioh check is being
performed. This is considered normal.
ABS operation sound
ABS operation (Long braking distance)1.Sound of the motor inside the ABS hydraulic unit. o perating (whine),
2. Sound is generated along with vibration of the b rake’ pedal.
3.When ABS operates, sound is generated from the vehi cle chassis due
brake application and release.
(Thump: suspension; squeak: tires)
For road surfaces such as snow-covered roads and gravel roads, the braking distance forvehicles with ABS can sometimes be longer than that for other vehicles. Accordingly,
advise the customer to drive safely on such roads by lowering the vehicle speed and not
being overconfident.
Diagnosis detection condition depends on the diagno stic trouble code.
Make sure that checking requirements listed in the “Comment” are satisfied when checking the trouble
symptom again after the diagnostic trouble code has been erased.
