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 04863761). 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.

PROCEDURE FOR 6.5 MM SHIM

6.    On the 2500 series vehicles equipped with 3850 or 4850 lb front GAWR (Gross Axle Weight Rating) and single rear wheels the following procedure should be used to determine the proper wheel stud to be used:

A.    Determine the GAWR (Gross Axle Weight Rating) of the front axle of the vehicle from the Vehicle Safety Certification Label located on the drivers door lock pillar. If the vehicle is equipped with:

3850 lb. front axle rating use stud part number 04864185.

4850 lb. front axle rating and single rear wheels use stud part number 04864187.

7.    Remove the 5.0 mm shim installed in step 5.

8.    Remove the brake caliper from the mounting.

9.    Remove the hub, rotor and bearing from the steering knuckle as outlined in the 1997 Ram Truck Service Manual (Publication Number 81-370-7108), pages 5-28 through 5-30.

10.   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.

CAUTION:    DO NOT ATTEMPT TO REMOVE THE WHEEL STUDS WHILE THE HUB, ROTOR AND BEARING ASSEMBLY IS INSTALLED ON THE SPINDLE OR BEARING DAMAGE WILL RESULT.

11.   Press the eight new, longer studs (p/ln 04864185 or 04864187) as determined above into the hub.

CAUTION:    BE SURE HUB IS SUPPORTED, LOAD REACTION MUST NOT BE TAKEN THROUGH THE BEARING.
