Crankshaft Main Bearing Sets

The main bearings are the bearings that enable your crankshaft to move freely. You’ll find them in between the engine block and the crankshaft. In that same area are located the rod bearings. They are between the crankshaft and the piston rod. When you start your engine and you hear a knock or your low oil pressure light is on, inspect the condition and the level of the oil.

If the oil is full and it’s clean, the knocking you hear might be caused by damaged or worn out main bearings. If your main bearings are bad or your rod bearings need to be replaced, they also could cause knocking when you accelerate. Main bearing damage can be caused by dirt or debris in the engine or a lack of proper lubrication.
