Check if the main bearing caps are marked to indicate their locations, which should be numbered consecutively from the front of the engine to the rear. If they aren't marked, use number stamping dies or a center-punch to mark them. Loosen the main bearing cap bolts 1/4-turn at a time until they can be removed by hand.

Inspect the crankshaft sensor wheel at the rear of the crankshaft for cracks, wear, and any other damage. If the sensor wheel is damaged, replace it, as damage to this component can result in severe driveability problems. To remove the sensor wheel from the crankshaft, remove the three retaining screws, and ensure to tighten the retaining screws when installing the sensor wheel.
