5. CAUTION: To prevent engine damage, do not remove the rear primary crankshaft flange bolts under any circumstances. If the flange is
removed and reinstalled, it may result in engine vibration and premature transmission component wear.
CAUTION: Drill only deep enough to penetrate the seal. Engine damage may occur if the seal is drilled too deep.
NOTE: On early build vehicles, if equipped, the wear sleeve will be removed separately.
Using a center punch, mark a location for 2 holes 180 degrees apart, 9.53 mm (0.37 inch) from the outer diameter of the crankshaft flange. Using a
drill bit of the appropriate size for the slide hammer dent puller attachment being used, drill a hole on each side of the crankshaft rear seal as
shown. Drill the holes to a depth of 8.76 mm (0.34 inch) to capture the metal case of the crankshaft seal as well as the wear sleeve.
