Front Differential Carrier Components / w/o Differential Lock:

Front Differential Carrier Components / w/ Differential Lock:

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

Maximum runout: 0.10 mm (0.0039 inch)





2. Check ring gear runout. Using a dial indicator, measure the ring gear runout.

Maximum runout: 0.10 mm (0.0039 inch)

If the runout is greater than the maximum, replace the ring gear and driven pinion as a set.





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

Preload (at starting): 0.5 - 0.8 Nm (4.3 - 6.9 inch lbs.)

5. Check total preload. Using a torque wrench, measure the preload.

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.





6. w/o Differential lock: check side gear backlash. Using a dial indicator, measure the side gear backlash with holding one pinion gear toward the case.

Backlash: 0.05 - 0.20 mm (0.0020 - 0.0079 inch) If the backlash is not within the specification, install the correct thrust washers.

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