DI-37 Rear Differential (T-type) DIFFERENTIALS (4) Align the arrow mark on the differential car- rier with the arrow mark on the side retainer when installing the side retainer. NOTE: Be careful that the side bearing outer race is not damaged by the bearing roller. (5) Tighten the side retainer bolts. Tightening torque: 10.5 N·m (1.1 kgf-m, 7.7 ft-lb) (6) Measure the hypoid driven gear to drive pin- ion backlash. Set the magnet base on differen- tial carrier. Align the contact point of dial gauge with tooth face of hypoid driven gear, and move hypoid driven gear while holding drive pinion still. Read the value indicated on dial gauge. If the backlash is outside the standard range, ad- just the side retainer shim by the following method. • When backlash is less than 0.1 mm (0.004 in): Reduce the thickness of shim on the back side of the hypoid driven gear and increase the thickness of shims on the teeth side of the hy- poid driven gear. • When backlash exceeds 0.2 mm (0.008 in): Increase the thickness of shim on the back side of the hypoid driven gear and reduce the thick- ness of shims on the teeth side of the hypoid driven gear. Backlash: 0.10 — 0.20 mm (0.004 — 0.008 in) (7) Measure the total preload of the drive pin- ion. If the total preload is not within specifica- tion, adjust the thickness of side retainer shims, increasing/reducing both shims by an even amount at a time. Total preload: 20.7 — 54.4 N (2.1 — 5.5 kgf, 4.7 — 12.2 lbf) (A) Arrow mark (on the side retainer) DI-00543 (B) (A) DI-00487 DI-00099 |
