| Title: AXLE AND DIFFERENTIAL: REAR DIFFERENTIAL CARRIER ASSEMBLY: DISASSEMBLY (2008 LX570) | ||
DISASSEMBLY
1. INSPECT RUNOUT OF REAR DRIVE PINION COMPANION FLANGE
|
(a) Using a dial indicator, measure the runout of the companion flange vertically and laterally. Maximum Runout:
If the runout is more than the maximum, replace the companion flange. |
2. INSPECT RUNOUT OF DIFFERENTIAL RING GEAR
|
(a) Using a dial indicator, measure the ring gear runout. Maximum runout: 0.05 mm (0.00197 in.) If the runout is more than the maximum, replace the ring gear. |
3. INSPECT DIFFERENTIAL RING GEAR BACKLASH
|
(a) Using a dial indicator, measure the ring gear backlash. Standard backlash: 0.10 to 0.20 mm (0.00394 to 0.00787 in.) HINT:
Measure at 3 or more positions around the circumference of the ring gear. If the backlash is not as specified, adjust the side bearing preload or repair as necessary. |
4. REMOVE DRIVE PINION COMPANION FLANGE REAR NUT
|
(a) Using SST and a hammer, unstake the nut. SST: 09930-00010 |
|
(b) Using SST to hold the companion flange, remove the nut. SST: 09330-00021 09330-00030 |
5. REMOVE REAR DRIVE PINION COMPANION FLANGE REAR SUB-ASSEMBLY
|
(a) Using SST, remove the companion flange. SST: 09950-30012 09951-03010 09953-03010 09954-03010 09955-03030 09956-03040 |
6. REMOVE REAR DIFFERENTIAL CARRIER OIL SEAL
|
(a) Using SST, remove the oil seal from the differential carrier. SST: 09308-10010 |
7. REMOVE REAR DIFFERENTIAL DRIVE PINION OIL SLINGER
8. REMOVE REAR DRIVE PINION FRONT TAPERED ROLLER BEARING
|
(a) Using SST, remove the front bearing (inner race) from the drive pinion. SST: 09556-22010 If the front bearing is damaged or worn, replace the bearing. |
9. REMOVE REAR DIFFERENTIAL BEARING ADJUSTING NUT LOCK
|
(a) Remove the 2 bolts and 2 adjusting nut locks. |
10. REMOVE DIFFERENTIAL CASE ASSEMBLY
|
(a) Place matchmarks on the bearing caps and differential carrier. |
(b) Remove the 4 bolts, 2 bearing caps and 2 adjusting nuts.
|
(c) Remove the differential case from the differential carrier. HINT:
Tag the 2 case bearing outer races to show the location for reassembly. |
11. REMOVE DIFFERENTIAL DRIVE PINION
(a) Remove the differential drive pinion from the differential carrier.
12. REMOVE REAR DIFFERENTIAL DRIVE PINION BEARING SPACER
13. REMOVE REAR DRIVE PINION REAR TAPERED ROLLER BEARING
|
(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. |
14. REMOVE REAR DIFFERENTIAL DRIVE PINION PLATE WASHER
15. REMOVE REAR DRIVE PINION FRONT TAPERED ROLLER BEARING
|
(a) Using a brass bar and hammer, tap out the bearing (outer race). |
16. REMOVE REAR DRIVE PINION REAR TAPERED ROLLER BEARING
|
(a) Using a brass bar and hammer, tap out the bearing (outer race). |
17. REMOVE DIFFERENTIAL RING GEAR
|
(a) Place matchmarks on the ring gear and differential case. |
(b) Remove the 12 ring gear set bolts.
(c) Using a plastic-faced hammer, tap on the ring gear to disconnect it from the differential case.
18. INSPECT RUNOUT OF DIFFERENTIAL CASE
HINT:
If the ring gear runout is at the maximum or less (see "Inspect Runout of Differential Ring Gear" procedure), this inspection is not necessary.
|
(a) Using a dial indicator, measure the differential case to the differential carrier. |
(b) Using a dial indicator, measure the differential case runout.
Maximum runout:
0.04 mm (0.00157 in.)
If the runout is more than the maximum, replace the differential case and side bearing as a set.
(c) Remove the differential case from the differential carrier.
19. REMOVE REAR DIFFERENTIAL CASE BEARING
|
(a) Using SST, remove the 2 side bearings (inner race) from the differential case. SST: 09950-00020 SST: 09950-00030 SST: 09950-40011 09957-04010 SST: 09950-60010 09951-00480 |
20. DISASSEMBLE DIFFERENTIAL CASE
|
(a) Place matchmarks on the differential case LH and RH. |
(b) Remove the 8 bolts uniformly, a little at a time.
(c) Using a plastic-faced hammer, disconnect the differential case LH and RH.
(d) Remove the 2 side gear thrust washers, 2 side gears, spider, 4 pinion gears and 4 pinion gear thrust washers.
