DESCRIPTION
A main bearing, also known as a crankshaft bearing, is a component found in the engine block of a truck. It supports the crankshaft and allows it to rotate smoothly. The main bearing is typically made of a strong material, such as steel or aluminum, and is designed to withstand the high pressure and heat generated by the engine's combustion process. The part number for this specific main bearing is 4089938. Over time, main bearings can wear down due to normal use or lack of proper maintenance, which can cause engine knocking or other issues if not addressed promptly.
