INSPECTION

Wash the disassembled parts and inspect them on the following points. Replace any part found defective.

Drive Pinion & Bearing

1. Inspect the drive pinion gear teeth for damage, wear or burning.

2. Inspect the bearings for wear or damage.

3. Measure the shim and adjust washer thickness.

Replace The Bearing

1. Remove the bearings with SST. SST [09950-20014]

It there is not enough clearance for the SST to hook on, draw out the bearing slightly with a chisel.

2. Remove the baering outer race witn SST SST [09608-35013]

Differential Case, Side Bearing & Ring Gear

1. Inspect the ring gear teeth for damage, wear or burning.

2. Inspect the side bearings for wear or damage.

3. Inspect the case for cracks.

Replace The Side Bearing

1. Remove the bearing with SST. SST [09950-20014]

2. Install the bearing with SST. SST [09505-20010]

Replace The Ring Gear

1. Loosen the attaching bolts uniformally, and remove the ring gear by tapping it with a plastic hammer.

Heat the ring gear to 90 - 110°C (194 -230°F) and quickly fit it into the case. Tighten the nuts at the specified torque. Tightening torque:

Toyota Pinion Bearing Preload

Install the drive pinion assembly to the differential carrier as shown in the figure, and tighten the nut at the specified torque.

Tightening torque: 20.0 — 24.0 kg-m (145 - 173 ft-lb)

1. Have the bearings lubricated with hypoid gear oil.

2. Install the same size shims and washer that wear used before disassembly, (for position and preload adjusting shim)

Measure the preload.

Preload (starting): New bearing 19-26 kg-cm (16.5 - 22.6 in.-lb) Reused bearing 9-13 kg-cm (7.8 - 11.3 in.-lb) If the preload is not within the specified limits, correct by selecting suitable adjusting washer and increasing or decreasing the number of adjusting shims (limited to 4 shims).

ASSEMBLY & ADJUSTMENT

Assemble the parts in the numerical order shown in the figure.

Coat hypoid gear oil on the bearings, thrust washers, and similar parts before assembling them.

Thrust Washer & Side Gear Thrust Washer & Pinion

Pinion Gear Thrust Washer Installation

0 Assemble the bearing cups to the side bearings and install the differential case to the carrier.

1. Use care not to intermix the left and right bearing cups.

2. Make sure that backlash has been provided between the ring gear and drive pinion.

1. Assemble the adjusting nuts to their respective carriers with the threads fitted on properly.

2. Screw in the two bearing cap bolts two or three turns and press down the bearing cap with hand.

1. If the bearing cap does not fit tightly on the carrier, the adjusting nut threads are not fitting properly so that operations 1 and 2 above must be repeated.

2. Make sure that the bearing cap matchmarks are aligned with that on the carrier.

0 Adjust The Side Bearing Preload

SST [09504-00010]

1. Tighten the bearing cap bolts until the spring washers are slightly compressed.

2. Tighten the adjusting nut on the ring gear side with SST so that the ring gear has a backlash of about 0.2 mm (0.008 in.).

3 With SST. tighten firmly the adjusting nut on the drive pinion side in order to snug down the bearing in the carrier. 4. Check to see if tightening of the adjusting nut creates ring gear backlash.

Differantial Pinion Pre Load Cute Puppy Love

With SST, sufficiently loosen the side bearing adjusting nut on the drive pinion side.

Set the adjusting nut to the zero preload position for the side bearing.

(1) Place a dial gauge on top of the bearing outer race.

(2) Tighten the other adjusting nut until the dial gauge pointer begins to move.

Toyota Cruiser Pinion Nut

7. Tighten adjusting nut 1 — 1.5 clicks from the zero preload position.

8. Measure the overall preload.

Preload (starting): (For both new and reused bearing) 4-6 kg-cm (3.5 - 5.2 in.-lb)

+ Drive pinion preload

Differential Gear Tooth Pattern

Adjust The Backlash

1. Adjust the backlash to the specified value with SST, turning the left and right adjusting nuts by equal amounts (such as loosening the left side one click and tightening the right side one click).

2. Tighten the bearing cap bolts at the specified torque.

Tightening torque:

Land Cruiser Gauge Face

Inspect The Tooth Contact

1. Inspect the contact between the ring gear and drive pinion teeth by coating red lead on the ring gear teeth.

1. Hold the companion flange steady with hand and rotate the ring gear, and inspect the contact pattern formed.

2. If the teeth are not contacting properly, correct by method shown in the figure.

2. Install the adjusting lock nut on each bearing cap, and stake the companion flange nut.
