Toyota Tundra (2015 year). Manual — part 798
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:
0.15 mm (0.00591 in.) or less
If the backlash is not within the specification, replace the side
Standard drive pinion preload (at starting):
1.62 to 2.25 N*m (17 to 22 kgf*cm, 15 to 19 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
Standard drive pinion preload plus 0.19 to 0.38 N*m (2 to 3
kgf*cm, 2 to 3 in.*lbf)
If necessary, disassemble and inspect the differential.
7. REMOVE REAR DRIVE PINION NUT
(a) Using SST and a hammer, unstake the nut.
SST: 09930-00010
DIFFERENTIAL: DIFFERENTIAL CARRIER ASSEMBLY (for 3UR-...
(b) Using SST to hold the companion flange, remove the nut.
SST: 09330-00021
09330-00030
8. REMOVE REAR DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY
(a) Using SST, remove the companion flange.

09953-04020
09952-04010
SST: 09955-04130
SST: 09958-04020
DIFFERENTIAL: DIFFERENTIAL CARRIER ASSEMBLY (for 3UR-...
(b) Remove the 2 preload adjusting shims.
12. REMOVE REAR DIFFERENTIAL CASE ASSEMBLY
(a) Place matchmarks on the bearing cap and differential carrier.

(b) Remove the 4 bolts and 2 differential bearing caps.
(c) Using SST and a plastic-faced hammer, remove the 2 plate
washers.
SST: 09504-22012
HINT:
Measure the plate washer thickness and note it down.
(d) Remove the differential case with the bearing outer races from the carrier.
HINT:
Tag the bearing outer races to show the location for reassembling.
13. REMOVE REAR DIFFERENTIAL DRIVE PINION
(a) Remove the differential drive pinion and bearing spacer from the
differential carrier.
14. REMOVE REAR DRIVE PINION REAR TAPERED ROLLER BEARING
DIFFERENTIAL: DIFFERENTIAL CARRIER ASSEMBLY (for 3UR-...
(a) Using SST and a press, press out the bearing (inner race).
SST: 09950-00020
If either the drive pinion or ring gear is damaged, replace them
as a set.
15. REMOVE REAR DIFFERENTIAL DRIVE PINION PLATE WASHER
16. REMOVE REAR DRIVE PINION FRONT TAPERED ROLLER BEARING
(a) Using SST, remove the bearing (outer race).
SST: 09308-00010
If the bearing is damaged during removal, replace it.
17. REMOVE DIFFERENTIAL OIL STORAGE RING
(a) Using a brass bar and hammer, tap out the storage ring.
18. REMOVE REAR DRIVE PINION REAR TAPERED ROLLER BEARING
(a) Using a brass bar and hammer, tap out the bearing (outer race).
If the bearing is damaged during removal, replace it.
