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
