2.INSPECT RUNOUT OF DRIVE PLATE & RING GEAR SUB-ASSY
a. Set up a dial indicator and measure the drive plate runout.
Maximum runout: 0.20 mm (0.0079 in.)
If runout is not within specification or if the ring gear is damaged, replace the drive plate. If installing a
new drive plate, note the orientation of the spacers and tighten the bolts.
Torque:
1st: 49 N.m (500 kgf.cm, 36 ft.lbf)
2nd: Turn extra 90°

If the runout is greater than the maximum, replace the drive pinion and ring gear.

22.INSPECT DIFFERENTIAL DRIVE PINION PRELOAD
a. Using SST and a torque wrench, measure the preload using the backlash of the drive pinion and
ring gear.
SST 09229-55010
Drive pinion preload (at starting):
0.5 to 0.8 N.m (5 to 8 kgf.cm, 4.3 to 6.9 in..lbf)
If the preload is not within the specification, adjust the rear differential drive pinion preload or repair as
necessar
y.

c. Using SST and a torque wrench, measure the preload.
Drive pinion preload (at starting):
New bearing:
1.5 to 2.0 N.m (15 to 21 kgf.cm, 13 to 18 in..lbf)
Reused bearing:
0.5 to 0.8 N.m (5 to 8 kgf.cm, 4.3 to 6.9 in..lbf)
HINT:
Do not apply hypoid gear oil if a new bearing is used.
Turn the bearing clockwise and counterclockwise several times to stabilize the bearing,
and then measure the backlash.
If the preload is not within the specification, adjust the rear differential drive pinion
preload or repair as necessar
y.

ADJUST TOTAL PRELOAD
a. Using SST and a torque wrench, measure the preload with the teeth of the drive pinion
and ring gear in contact.
b. SST 09229-55010
Total preload (at starting):
Drive pinion preload plus 0.46 to 1.37 N.m
(4.69 to 13.97 kgf.cm, 4.07 to 12.13 in..lbf)
If the preload is greater than the specification, replace the rear differential side
gear shaft snap ring of the ring gear's tooth surface side with a thinner one.

relay valve and locks the torque converter clutch.
If the ECM detects no lock-up after lock-up has been requested or if it detects lock-up when it is not requested,
the ECM interprets this as a fault in the shift solenoid valve SLU or lock-up system performance.
The ECM will turn on the MIL and store the DTC.
Example:
When any of the following is met, the system judges it as a malfunction.
a. There is a difference in rotation between before and after torque converters even when the ECM
commands lock-up.
(Engine speed is at least 75 rpm greater than input turbine speed.)
b. There is no difference in rotation between before and after torque converters even when the ECM
commands lock-up off.
(The difference between engine speed and input turbine speed is less than 35 rpm.)
