13. CHECK FRONT BEARING PRELOAD Using a torque wrench, measure the preload of the backlash between the drive pinion and ring gear. Preload: New bearing 12 — 19 kg-cm (10.4 — 16.5 in.-lb, 1.2 — 1.9 N-m) Reused bearing 6 — 10 kg-cm (5.2 — 8.7 in.-lb, 0.6 — 1.0 N-m) (a) If preload is greater than specification, replace the bearing spacer. (b) If the preload is less than specification, retighten the nut 130 kg-cm (9 ft-lb, 13 N-m) at a time until the specified preload is reached. If the maximum torque is exceeded while retightening the nut, replace the bearing spacer and repeat the preload procedure. Do not back off the pinion nut to reduce the preload. Maximum torque: 2,400 kg-cm (174 ft-lb, 235 N-m) 14. CHECK RUNOUT OF COMPANION FLANGE Using a dial indicator, measure the lateral and radial runout of the companion flange. If the runout is greater than the maximum, inspect the bearings. Maximum lateral runout: 0.10 mm (0.0039 in.) Maximum radial runout: 0.10 mm (0.0039 in.) 15. STAKE DRIVE PINION NUT 16. INSTALL SIDE GEAR SHAFT OIL SEAL (a) Coat the oil seal lip with MP grease No. 2. (b) Using SST, drive in the oil seal until it is flush with the carrier end surface. SST 09550-22011 (09550-00020 and 09550-00030)
