Worn crankshaft main bearings can show up as a deep knock from the lower engine or as low oil pressure. Before you replace the bearings, rule out a low oil level, a weak oil pump or a faulty pressure sensor, since each can also lower the oil pressure reading. The set meets or exceeds OEM specifications.
