1500 SERIES SHIMMING PROCEDURE:

1.    Remove the retainers holding the rotor in place on the wheel studs. With wheel and retainers removed, install 3.5 mm shim (p/ln 04863756). Make sure that the shim is installed as marked "THIS SIDE OUT."

2.    Install the wheel making sure that it is centered on the studs and partially tighten all of the lug nuts following the pattern given in the 1997 Ram Truck Service Manual (Publication Number 81-370-7108) page 22-10.

3. Finish torquing the lug nuts to 108 - 150 Nm (80-110 ft. lbs.) .

4.    Road test the vehicle again as described in step 7 through 11 in the diagnosis section of the Suspension Geometry Evaluation. If the condition is corrected, the repair is complete. If the vehicle drifts to the opposite direction as originally found then repeat steps 1 through 3 on that side, using a 2.0 mm shim (p/n 04863753).

NOTE:    AFTER THE REPAIR IS COMPLETE, INSTALL NEW ROTOR RETAINERS (P/N 06026430) ON OPPOSING STUDS.

5. If the vehicle continues to drift in the same direction as originally found then a thicker shim must be used. Repeat steps 1 through 3 using a 5.0 mm shim (p/ln 04863757). Road test the vehicle again as described in step 7 through 11 in the diagnosis section of the Suspension Geometry Evaluation. If the condition is corrected, the repair is complete. However, if the vehicle still continues to drift in the same direction as originally found, then a thicker than 5.0 mm shim must be used. In this event the wheel studs must be replaced with part number 04864186, provided in kit number 04864546 Wheel Shim & Stud Kit.
