Before removing the crankshaft, measure the endplay by mounting a dial indicator aligned with the crankshaft and touching its end. Pry the crankshaft to the rear and zero the dial indicator, then pry it to the front and check the reading; the distance traveled indicates the endplay, which typically ranges from 0.003 to 0.010 inches (0.076 to 0.254 mm). If the endplay exceeds this range, inspect the crankshaft thrust surfaces for wear after removal, and if no wear is found, new main bearings should resolve the issue. If a dial indicator is unavailable, use feeler gauges by prying the crankshaft to the front and slipping the gauges between the crankshaft and the thrust bearing or washer to measure clearance. For 3.6L V6 engines, remove the windage tray bolts in reverse order of installation. For 2.5L four-cylinder and six-cylinder engines, check if the main bearing caps are marked for their locations, numbering them consecutively from front to rear if necessary, and ensure the cast-in arrow on the main cap points to the front. For 2.4L four-cylinder engines, loosen the main bearing cap/bed plate fasteners gradually until they can be removed by hand, taking care not to drop the bearing inserts. For 3.6L V6 engines, remove the windage tray bolts, main cap bolts, and cross-bolts, purchasing new bolts for reassembly, and tap the caps with a soft-face hammer to separate them from the block, using bolts as levers if needed. For 2007 and later 3.8L V6 engines, remove the main cap cross-bolts and purchase new ones for reassembly, while for all other engines, follow the same procedure as previously described. Finally, carefully lift the crankshaft out of the engine, ideally with assistance due to its weight, and with the bearing inserts in place, reinstall the main bearing caps/bed plate onto the engine block, tightening the fasteners finger-tight.
