Turning Angle Inspection
Use commercially-available computerized four wheel
alignment equipment to measure wheel alignment(caster. camber, toe, and turning angle). Followthe
equiDment manufacturer's instructions.
1. Turn the steering wheel fullytotherightandleft
while applying the brake, and check the turning
angles of both front wheels, lf the turning angle is
not within the specification or the inward turning
angles differ between the right and left side, go to
steD 2.
Turning angle:
lnward: 34'00'+ 2'
Outward: 28'00' {reference)
Check the toe. lf it is correct, but the turning angle

3. Set up the dial gauge against the hub flange as
shown, and measure the bearing end play moving
the brake disc inward and outward.
Bearing end play:
Standard:
Front/rear: 0 0.05 mm {0 0.002 in.}

BallJoint Removal
Special Tools Required
Ball ioint remover.2S mm 07MAC-SL00200
Always use a ball joint remover to disconnect a ball
joint. Do not strike the housing or any other part of
the ball joint connection to disconnect it.
'1, Install a hex nut (A) ontothethreadsoftheballjoint
{B). Make sure the nut is flush with the balljoint pin
end to prevent damage to the threaded end of the
ball ioint oin.
Apply grease to the special tool on the areas shown(A). This will ease installation of the tool and
prevent damage to the pressure bolt {B) threads.

After adjusting the adjusting bolt, make sure the
head (C) of the adjusting bolt is in the position
shown to allow the jaw to pivot.
With a wrench, tighten the pressure bolt until the
ball ioint pin pops loose from the steering arm or
knuckle. lf necessary. apply penetrating type
lubricant to loosen the ball joint pin
NOTE: Do not use pneumatic or electric tools on
the pressure bolt.
Remove the tool, then remove the nut from the end
ofthe balljoint pin, and pullthe balljoint out ofthe
steering arm or knuckle. Inspectthe balljoint boot,
and replace it if damaged.
