Roadmaster V8-350 5.7L VIN P MFI (1995)
proper side bearing preload. Select shims to adjust backlash as follows:
a. If backlash is excessive, increase thickness of shim on gear tooth side and decrease thickness of shim on opposite side by the same amount.
b. If backlash is less than specified, decrease thickness of shim on gear tooth side while increasing thickness of opposite shim by the same
amount. Each 0.002 inch change in shim thickness alters backlash by 0.001 inch.
10. Reinstall differential assembly, shims and bearing caps, torque bearing cap bolts to 55 ft. lbs., then recheck backlash and adjust as needed.
11. If side bearing preload was set to zero during side bearing preload adjustment, proceed as follows:
a. Remove both bearing caps and shim packs, keeping shim packs in respective left or right positions.
b. Select left side differential preload shim from specifications chart and insert shim between left bearing race and spacer, then install left bearing
cap with bolts hand tight.
c. Select right side differential preload shim from specifications chart and insert shim between right bearing race and spacer using a soft faced
hammer.
d. Install right bearing cap and torque all cap bolts to 55 ft. lbs.
12. Ensure ring gear teeth are clean and free from oil, then coat both drive and coast side of each tooth with marking compound.
13. Apply braking force to load ring gear, then rotate driveshaft yoke with wrench so that ring gear rotates one full revolution in each direction. Test
made without loading gears will not yield satisfactory pattern, excessive rotating of gears is not recommended.
14. Compare gear tooth pattern with Fig. 16, and correct assembly adjustments as needed.
15. When proper gear tooth contact pattern has been obtained, clean marking compound from gears.
16. Install axles and driveshaft. Refer to Drive/Propeller Shafts, Bearings and Joints for procedures. See: Drive/Propeller Shafts, Bearings and
Joints/Drive/Propeller Shaft/Service and Repair
17. Install rear cover using RTV or new gasket and torque cover bolts to 20 ft. lbs., then fill rear axle with appropriate lubricant.
18. On models equipped with limited slip differential, add additive No. 1050428 or equivalent to rear axle lubricant.
