Toyota Tundra. Manual — part 1016

HINT:

Measure at 3 or more positions around the circumference of the ring gear.

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

4. INSPECT DIFFERENTIAL SIDE GEAR BACKLASH

a. Using a dial indicator, measure the side gear backlash while holding one pinion gear toward the

case.

Standard backlash: 0.05 to 0.20 mm (0.00197 to 0.00788 in.)

If the backlash is not within the specified value, replace the side gear thrust washer with one of a
different thickness.

5. INSPECT DIFFERENTIAL DRIVE PINION PRELOAD

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

Standard drive pinion preload (at starting): 0.85 to 1.37 N*m (9 to 13 kgf*cm, 8 to 12 in.*lbf)

If necessary, disassemble and inspect the differential.

6. INSPECT TOTAL PRELOAD

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

contact.

Standard total preload (at starting): Standard drive pinion preload plus 0.24 to 0.46 N*m (3
to 4 kgf*cm, 3 to 4 in.*lbf)

If necessary, disassemble and inspect the differential.
