The crankshaft can only be removed after the engine has been taken out of the vehicle, assuming that the flywheel/driveplate, timing belt, oil pan, oil pump, front and rear oil seal housings, and piston/connecting rod assemblies have been detached. For 2011 and later 1.8L and all 2014 and later 2.0L engines, a one-piece main bearing cap assembly known as the lower crankcase is utilized instead of individual main bearing caps, while 1.4L and 1.6L engines require the removal of a ladder frame or lower crankcase to access the main bearing caps. Before removing the crankshaft, check the endplay using a dial indicator or feeler gauges to measure the clearance between the crankshaft and thrust main bearing. Ensure the crankshaft sensor wheel and Crankshaft Position (CKP) sensor have the proper clearance, tightening the CKP sensor bolt if necessary. For 2010 and earlier 1.8L and 2012 and earlier 2.0L engines, verify that the main bearing caps are marked for their locations, loosening the bolts gradually for removal. Gently tap the caps with a soft-face hammer to separate them from the engine block, using bolts as levers if needed. For 1.4L and 1.6L engines, remove the ladder frame mounting bolts and check for markings on the main bearing caps, loosening the bolts for removal. Carefully lift the crankshaft straight out of the engine, ensuring not to damage the reluctor ring for the crankshaft position sensor, and return the bearing inserts and caps to their respective locations, tightening the bolts finger tight.

Clean the faces of the bearings in the caps, apply lubricant, and install the caps in their original locations with the arrows pointing toward the front of the engine. Tighten the mounting bolts until all the caps are seated.

Check the rest of the crankshaft for cracks and other damage. It should be Magnafluxed to reveal hidden cracks, which an automotive machine shop will handle.
