LS 430 V8-4.3L (3UZ-FE) (2002)
b. Tighten the 16 bolts.
Torque: 22 Nm (225 kgf-cm, 16 ft. lbs.)
13. CHECK RING GEAR BACKLASH
Using a dial indicator, measure the backlash of the ring gear at 3 positions at least.
Backlash: 0.08 - 0.13 mm (0.0031 - 0.0051 inch)
NOTICE: The difference between the maximum and minimum measure values must be less than 0.05 mm (0.0020 inch).
HINT: The measured values should be used as reference when selecting washers, so take a note of the values.
If the backlash is not within the specification replace the washer on the ring gear side with one of a different thickness using the following
procedure.
Adjusting washer thickness
14. MEASURE TOTAL PRELOAD
Using SST and a torque wrench, measure the preload with the teeth of the drive pinion and ring gear in contact.
SST 09229-55010
Total preload (at starting):
Drive pinion pre-read plus 0.5 - 0.8 Nm (5 - 8 kgf-cm, 4.3 - 6.9 inch lbs.)
If the measured preload is less than the specification, replace the washer of the ring gear's tooth surface side with a thicker one.
If the preload is greater than the specification, replace the washer of the ring gear's tooth surface side with a thinner one.
