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/n 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/n 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.
PROCEDURE FOR 6.5 MM SHIM
6. Remove the brake caliper from the mounting and remove the rotor retainers.
7. Remove the rotor from the steering knuckle as outlined in the 1997 Ram Truck Service Manual (Publication Number 81-370-7108), pages 5-28 through 5-30.
CAUTION:
DO NOT ATTEMPT TO REMOVE THE WHEEL STUDS WHILE THE HUB IS INSTALLED ON THE SPINDLE OR BEARING DAMAGE WILL RESULT.
8. Press the original wheel studs out of the hub as outlined in the 1997 Ram Truck Service Manual (Publication Number 81-370-7108) page 2-19.
9. Press the five new, longer studs (P/N 04864186) into the hub.
CAUTION:
BE SURE HUB IS SUPPORTED, LOAD REACTION MUST NOT BE TAKEN THROUGH THE BEARING.
10. Install the rotor, then install the caliper assembly.
11. Install a 6.5 mm shim (p/n 04863758) on the hub over the rotor. Make sure the shim is installed as marked "THIS SIDE OUT." Install two retainers (p/n 06026430) on the studs on opposite sides of the rotor to retain the shim.
12. Install the wheel on the rotor, install lug nuts. Make sure that the wheel 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.
13. Finish tightening the lug nuts to 108 - 150 Nm (80-110 ft. lbs.) following pattern given on page 22-9 and 22-10.
14. Road test the vehicle to insure that drift is now corrected.
CAUTION:
DO NOT USE MORE THAN ONE SHIM ON A WHEEL OR SPACE THE WHEEL MORE THAN 6.5 MM AWAY FROM THE ROTOR.
DO NOT PERFORM THIS PROCEDURE FOR ANY CONDITION(S) OTHER THAN THE ONE DISCUSSED IN THIS CHASSIS DYNAMICS DIAGNOSTIC PROCESS.
DO NOT INSTALL THESE SHIMS ON THE REAR OF A VEHICLE.
