![background image](/lexus/ls_460_rwd/v8-4.6l_(1ur-fse)/Page-1529045.png)
New bearing
1.22 to 1.80 N*m (12.4 to 18.4 kgf*cm, 10.8 to 15.9 in.*lbf)
Reused bearing
0.5 to 0.8 N*m (5.1 to 8.2 kgf*cm, 4.4 to 7.1 in.*lbf)
NOTICE:
*
For a more accurate measurement, rotate the flange forward and backward several times before the measurement.
*
Check the starting torque of the drive pinion for use with the total preload inspection.
*
The bearing spacer is made of plastic and changes shape when used. If the starting torque of the drive pinion is exceeded by
mistake, make sure to replace the bearing spacer with a new one.
*
If the starting torque of the drive pinion is exceeded, replace the bearing spacer.
*
If the starting torque of the drive pinion is insufficient, tighten the drive pinion nut 5 to 10° at a time.
*
Repeat the adjustment as necessary until the starting torque matches the specified torque.
Maximum torque:
T=490 N*m (5000 kgf*cm)
NOTICE:
*
If the tightening torque of the pinion nut exceeds the specified torque but the drive pinion starting torque is still insufficient,
loosen the pinion nut. Then check if the pinion nut and drive pinion threads are damaged.
*
If there are no problems, replace the bearing spacer, apply hypoid gear oil LSD to its threads and repeat the procedure above.
36. INSPECT TOTAL PRELOAD
(a) Using SST and a torque wrench, measure the total preload.
SST : 09229-55010
Standard total preload (at starting):
New bearing
1.68 to 3.17 N*m (17.1 to 32.3 kgf*cm, 14.9 to 28.1 in.*lbf)
Reused bearing
0.96 to 2.17 N*m (9.8 to 22.1 kgf*cm, 8.5 to 19.2 in.*lbf)
37. INSPECT DIFFERENTIAL RING GEAR BACKLASH
(a) Place a dial indicator so that it is perpendicular to the top of the ring gear on the tooth side.
