Assembly and InstallationFigure 4.19Differential Case and Ring Gear1. Install the Bearing cap and adjusting ring intothe bore of the integral bearing cap side ofthe differential.2. Install the differential case and ring gear assemblyinto the differential.3. Install the Bearing cap and adjusting ring intothe differential on the bolted-on bearing capside.4. Position the cap onto the differential. Installthe capscrews and tighten them to 115-140lb-ft (155-190 N.m).5. Adjust the differential bearings preload andring gear backlash. Check the tooth contactpatterns.Adjust Differential Bearing PreloadUse Method 1 or Method 2 below to adjust differentialbearing preload.1 - CAPSCREWS2 - LOCK PLATEFigure 4.20Specifications7. Install the Fork and locknut onto the drive pinionshaft.8. Fasten a Fork bar to the Fork to hold the drivepinion in position when you tighten the locknut.Figure 4.21. See the Section 9 to builda Fork bar.9. Tighten the locknut to 740-920 lb-ft (1000-1245 N•m).Remove the Fork bar.Differential bearingpre-loadExpansion betweenBearing caps5-20 lb-pol(5,8-23,0 N.m)0,006-0,013 pol.(0,15-0,33 mm)450 lbs.péMethod 11. Attach a dial indicator onto the differentialmounting flange so that the pointer is againstthe ring gear’s back surface.2. Use a T-bar wrench to loosen the bearing adjustingring that is opposite the ring gear. Figure4.23. The dial indicator will show a smallamount of endplay.1 - SPECIAL TOOLFigure 4.21MAINTENANCE MANUAL27
Assembly and InstallationFigure 4.25Figure 4.221 - LEVER must not touch bearings.4. Tighten the bearing adjusting ring until thedial indicator reads ZERO endplay. Move thedifferential ring to the LEFT and RIGHT asneeded. If necessary, repeat Step A or B.5. Tighten each bearing adjusting ring one notchfrom ZERO. Proceed to Check Ring GearRunout (Radial Movement) in this section.1 - lever Wrench2 - Adjusting Ring Opposite Ring GearFigure 4.233. Use one of the following procedures to movethe differential and ring gear to the LEFT andRIGHT while you read the dial indicator.A. Insert two lever between the bearing adjustingrings and the ends of the differentialcase. Figure 4.24. The lever must not touchthe differential bearings.B. Insert two lever between the differential case,or the ring gear and the carrier at locationsother than specified in Step A. Figure 4.25.The lever must not touch the differential bearings.Method 21. Hand-tighten both adjusting rings against thedifferential bearings.2. Use a micrometer to measure the oppositesurfaces of the bearing caps at X or Y. Figures4.26 e 4.27. Record the measurement3. Tighten each bearing adjusting ring one notch.4. Measure the opposite surfaces of the bearingcaps at X or Y again. Compare the measurementwith the one you obtained in Step2.Figure 4.261 - LEVER must not touch bearings.Figure 4.2428 MAINTENANCE MANUAL
