SA–70 SUSPENSION AND AXLE – REAR DIFFERENTIAL DIFFERENTIAL CARRIER ASSEMBLY 1. CONVENTIONAL DIFFERENTIAL ONLY: ADJUST DIFFERENTIAL PINION GEAR BACKLASH (a) Install the proper thrust washers on the side gears. HINT: Using the table below, select thrust washers which will ensure that the backlash is within specification. Thrust washer thickness Thickness mm (in.) | Thickness mm (in.) 1.6 (0.063) | 1.8 (0.071) 1.7 (0.067) | — (b) Install the side gears, pinion gears, pinion gear thrust washers and pinion shaft in the differential case. HINT: Align the holes of the differential case and pinion shaft. (c) Push the side gear shafts gently into the differential case by hand and install them. (d) Measure the pinion gear backlash while holding one side gear toward the case. Backlash: 0.05–0.20 mm (0.0020–0.0079 in.) If the backlash is not within the specification, install different thickness side gear thrust washers. (e) Remove the side gear shaft. 2. CONVENTIONAL DIFFERENTIAL ONLY: INSTALL RING GEAR ON DIFFERENTIAL CASE (a) Using a hammer and pin punch, install the straight pin through the differential case and hole of the pinion shaft. (b) Stake the differential case. 3. INSTALL RING GEAR ON DIFFERENTIAL CASE (a) Clean the contact surfaces of the differential case and the threads of the ring gear and differential case. (b) Heat the ring gear in boiling water. (c) Carefully remove the ring gear from the boiling water. SA1181 SA117B R07224 SA1280 Holding Boiling Water SA1141
