Automatic Trans: Overhaul: Differential: Reassembly

Set speedometer drive gear onto ring gear and case assembly.
NOTE: Do not reuse side bearings if they were removed.

Fig 1: Installing Speedometer Drive Gear
Press side bearing (side opposite ring gear) into ring gear and case assembly with SST(0K990 175 AA1).

Fig 2: Installing Side Bearing Opposite Ring Gear
Press on other side bearing (ring gear side) in same manner.
Install pinion gears and thrust washers into case.
Install pinion shaft.

Fig 3: Installing Pinion Shaft
Install spring pin, and stake hole to prevent spring pin from coming out of gear case.

Fig 4: Installing Spring Pin
Install thrust washers and side gears into gear case at same time, then rotate them around pinion gears and align them with drive shaft holes.
NOTE: Be certain that both side gears are centered in their respective drive shaft holes. If not, remove both side gears and reinstall them again.

Fig 5: Centering Side Gears To Align For Drive Shaft
Measure backlash of side gears and pinion gears as follows:
1. Install left and right drive shafts in differential assembly.
2. Support drive shafts on V-blocks.
3. Measure backlash of both pinion gears.
Backlash

Standard: 0.001~0.004 in. (0.025~0.1 mm)

Maximum: 0.020 in. (0.5 mm)

If backlash is not within specification, replace differential assembly.
