Component Disassembly & Reassembly: Differential: Reassembly
- Using Race Remover/Installer (09351-32111) and Handle (09351-32130), install bearing outer race and shim in transaxle housing. Install bearing outer race and shim in transaxle case using race remover/installer and handle.
- Select thrust washers that will ensure correct side gear backlash. Thrust washers are available in thicknesses of .037-.047" (.95-1.20 mm) in .002" (.05 mm) increments. Install thrust washers and side gears in differential case.
- If possible, install same size thrust washers on both sides. Install pinion gears and pinion shaft. Check gear backlash to ensure proper thrust washers are used. When backlash is correct, using hammer and punch, drive lock pin through differential case and into pinion shaft. Stake differential case to retain lock pin.
- Using Adapter (09710-03160) and press, install side bearing on differential case. Install speedometer drive gear on differential case. Using Adapters (09351-32090 and 09315-31120) and press, install side bearing on differential case on speedometer drive gear side.
- Install differential in transaxle case. Install transaxle housing. Install bolts in correct locations and tighten bolts to 21 ft. lbs. (29 N.m). See Fig 2. Measure differential bearing preload, using Differential Preload Adapter (09564-32011) and an INCH-lb. torque wrench. See Fig 3.
- Preload must be within specification. Refer to DIFFERENTIAL PRELOAD SPECIFICATIONS . If preload is incorrect, remove differential from transaxle case and replace adjusting shim under bearing. Adjusting shims are available in thicknesses of .079-.114" (2.00-2.90 mm) in .002" (.05 mm) increments. Preload will change approximately 2.6-3.5 INCH lbs. (.3-.4 N.m) with each shim thickness.
- When correct preload is obtained, remove differential from transaxle case. Install ring gear on differential case. Clean ring gear and mounting surface. Heat ring gear to 212°F (100°C) in an oil bath. DO NOT heat ring gear at temperatures greater than 230°F (110°C). Align ring gear on differential case and install NEW bolts. Tighten bolts evenly to 72 ft. lbs. (97 N.m). See Fig 2.
- Stake locking tabs. Stake one tab flush with flat surface of nut. Stake 2nd tab against corner of nut on tightening side. Coat lip of oil seals with multipurpose grease. Use Seal Installer (09351-32150) and handle to install oil seals.
