Title: DIFFERENTIAL: REAR DIFFERENTIAL CARRIER ASSEMBLY: DISASSEMBLY; 2007 MY LX470 [08/2006 -        ]

DISASSEMBLY

1. FIX REAR DIFFERENTIAL CARRIER SUB-ASSEMBLY

2. INSPECT RUNOUT OF REAR DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY

(a) Using dial indicator, measure the vertical and lateral runout of the companion flange.

Maximum runout:

0.14 mm (0.0055 in.)

  • If the runout is greater than the maximum, replace the companion flange.

3. INSPECT RING GEAR RUNOUT

(a) Using a dial indicator, while holding the drive pinion flange, measure the ring gear runout.

Maximum runout:

0.05 mm (0.0020 in.)

  • If the runout is greater than the maximum, replace the ring gear.

4. INSPECT RING GEAR BACKLASH

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

Standard backlash:

0.13 to 0.18 mm (0.0051 to 0.0071 in.)

HINT:

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

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

5. INSPECT DRIVE PINION PRELOAD

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

Torque:

Standard preload (at start of torque) -

0.71 to 0.99 N·m {7.2 to 10.1 kgf·cm, 6.3 to 8.8in·lbf}

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.

Torque:

Standard total preload (at start of torque) -

0.38 to 0.63 N·m {3.9 to 6.5 kgf·cm, 3.4 to 5.6in·lbf}

  • If necessary, disassemble and inspect the differential.

7. INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION 2007 MY LX470 [08/2006 -        ]; DIFFERENTIAL: REAR DIFFERENTIAL CARRIER ASSEMBLY: REASSEMBLY+

8. REMOVE REAR DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY

(a) Using a chisel and hammer, unstake the nut.

(b) Using SST to hold the flange, remove the nut.

SST: 09330-00021

(c) Using SST, remove the companion flange.

SST: 09950-30012

9. REMOVE REAR DIFFERENTIAL CARRIER OIL SEAL

(a) Using SST, remove the oil seal from the differential carrier.

SST: 09308-10010

(b) Remove the oil seal.

10. REMOVE REAR DIFFERENTIAL DRIVE PINION OIL SLINGER

(a) Remove the oil slinger.

11. REMOVE REAR DRIVE PINION FRONT TAPERED ROLLER BEARING

(a) Using SST, remove the front bearing from the drive pinion.

SST: 09556-22010

  • If the front bearing is damaged or worn, replace the bearing.

12. REMOVE REAR DIFFERENTIAL CASE SUB-ASSEMBLY

(a) Place matchmarks on the bearing cap and differential carrier.

(b) Remove the 2 bolts and adjusting nut locks.

(c) Remove the 4 bolts, 2 bearing caps and adjusting nuts.

HINT:

Tag the disassembled parts to show the location for reassembling.

(d) Remove the differential case with the bearing outer races from the carrier.

HINT:

Tag the disassembled parts to show the location for reassembling.

13. REMOVE REAR DRIVE PINION REAR TAPERED ROLLER BEARING

(a) Using SST and a press, remove the rear bearing from the drive pinion.

SST: 09950-00020

HINT:

If the drive pinion or ring gear is damaged, replace them as a set.

(b) Remove the plate washer from the drive pinion.

14. REMOVE BEARING OUTER RACE

(a) Using a brass bar and hammer, remove the outer races.

15. REMOVE RING GEAR

(a) Place matchmarks on the ring gear and differential case.

(b) Remove the 12 ring gear set bolts.

(c) Using a plastic hammer, tap on the ring gear to remove it from the differential case.

16. INSPECT DIFFERENTIAL CASE RUNOUT

(a) Place the bearing outer races on their respective bearings. Check that the right and left outer races are not interchanged.

(b) Install the differential case in the differential carrier.

(c) Tighten the adjusting nut just to the point where there is no play in the bearing.

(d) Align the matchmarks on the bearing cap and differential carrier.

(e) Install and uniformly tighten the 4 bearing cap bolts a little at a time.

(f) Using a dial indicator, measure the differential case runout.

Maximum runout:

0.04 mm (0.0016 in.)

(g) Remove the differential case.

17. REMOVE REAR DIFFERENTIAL CASE BEARING

(a) Using SST, remove the 2 side bearings from the differential case.

18. REMOVE DISASSEMBLE DIFFERENTIAL CASE

(a) Place matchmarks on the RH and LH differential cases.

(b) Remove the 8 bolts uniformly, a little at a time.

(c) Using a plastic-faced hammer, separate the RH and LH differential cases.
