4.
Install case flange half over top cone and side gear. Install and snug tighten two retaining bolts on either side of case.
5.
Place differential case in suitable vise, then tighten vise to overcome spring preload tension.

Differential Case Installation
1.
Apply suitable axle lubricant to differential bearing bores.
2.
Place differential bearing cups on bearings, then set differential assembly in axle housing. If ring gear and pinion gear have punch marks,
assemble ring gear in carrier so that marked tooth on pinion is indexed between the marked teeth of ring gear.
3.
On 6.75 inch axles, install differential gauge disc .2 inch (5.0 mm) thick on left side (tool No. T78P-4136-B1) and .3 inch (7.6mm) thick on right
side (tool No. T78P-4136-B2). Install bearing caps using reference marks made during removal. Install bolts and torque to 30 ft. lbs. Install
adjuster tool No. T78P-4136-B into left side axle tube and torque to 40 inch lbs. to position differential case towards pinion side.
4.
Install a .265 inch shim on left side of case, then install bearing cap and tighten bolts finger tight. Install progressively larger shims on right side of
case until the largest shim selected can be installed with a slight drag. Install bearing cap and torque all bolts to 70---85 ft. lbs.
5.
On all axles, rotate differential several turns in either direction to ensure free rotation and to seat bearings.
