Operational Check
Set the parking brake and block the rear wheels.
Raise the front of the vehicle, and support it with
safety stands in the proper locations (see section 1).
With the engine off, shift the transmission into lstgear,
Rotate either front wheel bv hand and check that
the other wheel rotates in the opposite direction.
lf the opposite tront wheel does not rotste, or if voucannot spin the front wheels at all, the limited slip
differential is faulty and should be roplaced.
Rotating Torque Check
Setting parking brake and block the rear wheels.
Raise the front of the vehicle, and support it with
safety stands in proper locations (see section 1).
With the engine off, shift the transmission into
Neutral.
Measure the rotating torque with a beam-type
torquo wrench in the direction shown, Rotate the
torque wrench morg than two complete turns and
take the maximum reading.
Shift the transmission into 1st gear and measure
the rotating torque again.
Calculate the rotating torque:
Service Limit:
Measur€ment from steD 5
Measurementfrom step 4 =--
For example:
7.8 N.m (0.8 kgf.m)
zg N"ll (03 kgf'ntl = z'ot > z''
Repeat step 3 through 6 for the other wheel.
Replace the limited slip differential assembly if the
rotsting lorque is lower than the service limit.

Removal (cont'd)
Remove the cotter pin from the ball joint pin and
remove the nut.
Install the 10 mm hex nut on the ball ioint.
Be sure that the 10 mm hex nut is flush with the ball
joint pin end, or the threaded section of the ball
joint pin might be damaged by the ball joint re-
mover.
NOTE: Remove the ball joint using the special tool.
Refer to section 18 for the ball joint remover usage
instructions.
Separate the tie-rod ball ioint and knuckle using the
special tool.
CAUTION: Avoid damaging th. ball ioint boot.
