RAM 2500 Truck 4WD V8-5.2L VIN Y (2000)
12. Tighten pinion nut as follows for 248 RBI axles:
a. Using Yoke Holder 6719, and a torque wrench set at 447 Nm (330 ft. lbs.), crush collapsible spacer until bearing end play is taken up.
Fig. 31
b. Slowly tighten the nut in 6.8 Nm (5 ft. lbs.) increments until the rotating torque is achieved. Measure the rotating torque frequently to avoid
over crushing the collapsible spacer (Fig. 31).
13. Tighten pinion nut as follows for 267 RBI axles:
a. If the rotating torque is greater than the desired rotating torque, remove the pinion yoke and decrease the thickness of the solid shim pack.
Decreasing the shim pack thickness by 0.025 mm (0.001 inch) will increase the rotating torque approximately 0.9 Nm (8 inch lbs.).
b. Slowly tighten the nut in 6.8 Nm (5 ft. lbs.) increments until the rotating torque or tightening torque of 447 Nm (330 ft. lbs.) is achieved.
Measure the rotating torque frequently to avoid excessively preloading the pinion bearings (Fig. 31).
c. If the maximum tightening torque is reached prior to achieving the desired rotating torque, remove the pinion yoke and increase the thickness
of the solid shim pack. Increasing the shim pack thickness by 0.025 mm (0.001 inch) will decrease the rotating torque approximately 0.9 Nm
(8 inch lbs.).
14. Check bearing rotating torque with an inch pound torque wrench (Fig. 31). The torque necessary to rotate the pinion gear should be:
^
Original Bearings - 1 to 3 Nm (10 to 20 inch lbs.).
^
New Bearings - 2 to 5 Nm (15 to 35 inch lbs.).
15. Align previously made marks on yoke and propeller shaft and install propeller shaft.
16. Install differential housing into the axle housing.
