Toyota Tundra (2015 year). Manual - part 814

(a) Install the front differential union.

22. ADJUST BACKLASH BETWEEN DIFFERENTIAL RING GEAR AND DIFFERENTIAL DRIVE

PINION

(a) Using SST and a dial indicator, measure the ring gear backlash.

SST: 09564-33010

Standard backlash:

0.17 to 0.27 mm (0.00670 to 0.01062 in.)

If the backlash is not within the specification, adjust it by either

HINT:

There should be no clearance between the plate washer and
differential case.
Make sure that there is ring gear backlash.

23. INSPECT TOTAL PRELOAD

(a) Using a torque wrench, measure the preload with the teeth of

the drive pinion and ring gear in contact.

Standard Drive Pinion Preload Plus:

BEARING

SPECIFIED CONDITION

New

Drive pinion preload + 1.61 to 2.41 N*m (17 to 24

kgf*cm, 15 to 21 in.*lbf)

Reused

Drive pinion preload + 1.33 to 2.13 N*m (14 to 21

kgf*cm, 12 to 18 in.*lbf)

NOTICE:

Record the differential ring gear preload.

If necessary, disassemble and inspect the differential.

24. INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION

(a) Remove the bearing retainer and differential case.

(b) Coat 3 or 4 teeth at 3 different positions on the ring gear with

Prussian blue.

(d) Install the differential cross shaft bearing retainer and front

differential front support assembly LH with the 14 bolts.

Torque:

for bolt A -

65 N·m {633 kgf·cm, 48ft·lbf}

for bolt B -

155 N·m {1581 kgf·cm, 114ft·lbf}

(e) Hold the companion flange firmly and rotate the ring gear in both directions.

(f) Remove the differential case, side bearing retainer and differential case.

(g) Inspect the tooth contact pattern.
