Without Differential Lock

Differential Carrier (3RZ-FE, 5VZ-FE w/o Differential Lock):





INSPECTION
1. Check runout of companion flange. Using a dial indicator, measure the vertical and lateral runout of the companion flange.








Maximum vertical runout: 0.09 mm (0.0035 inch)
Maximum lateral runout: 0.09 mm (0.0035 inch) If the runout is not within the specification, replace the companion flange.





2. Check ring gear runout. Using a dial indicator, measure the ring gear runout.
Maximum runout: 0.05 mm (0.0020 inch) If the runout is not within the specification, replace the ring gear.





3. Check ring gear backlash. Using a dial indicator, measure the ring gear backlash.

Backlash: 0.13 - 0.18 mm (0.0051 - 0.0071 inch)

If the backlash is not within the specification, adjust the side bearing preload or repair as necessary.

4. Check tooth contact between ring gear and drive pinion.





5. Check side gear backlash. Measure the side gear backlash with holding one pinion gear toward the case.

Backlash: 0.05 - 0.20 mm (0.0020 - 0.0079 inch)





6. Check drive pinion preload. Using a torque wrench, measure the preload of backlash between the drive pinion and ring gear.

Preload (at starting): 0.6 - 0.9 Nm (5.7 - 8.3 inch lbs.)

7. Check total preload. Using a torque wrench, measure the preload with the teeth of the drive pinion and ring gear in contact.

Total preload (at starting):
Drive pinion preload plus: 0.4 - 0.6 Nm (3.5 - 5.2 inch lbs.)

If necessary, disassemble and inspect the differential.
