while holding one pinion gear toward the differential case.

Using a torque wrench, measure the total preload.
Total preload (at starting):
In addition to drive pinion preload
3 ± 5 kg±cm (2.6 ± 4.3 in.±Ib, 0.3 ± 0.5 N±m)
If necessary disassembly and inspect a differential. 7. MEASURE DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of the
backlash between the drive pinion and ring gear.
Preload (at staring):
5±8kg±cm (4.3±6.9in.±Ib,0.5±0.8N±n) 5. CHECK TOOTH CONTACT (See page RA±45)
