Question

Accepted Answer

Replacing the rear main seal in a 2012 GMC Terrain can cost between $8 and $36. The rear main seal is crucial for allowing the crankshaft to exit the engine case and connect to the flywheel or flex plate to transfer power to the transmission. It also prevents engine oil from leaking out and helps keep the main bearings lubricated. Repairing or replacing a rear main seal can be costly, typically exceeding $600, as it often requires removing the transmission and sometimes even part of the engine.
