What does a rear main crankshaft seal do?

The rear main crankshaft seal is located at the back of the engine where the crankshaft exits the engine block. Its primary job is to prevent engine oil from leaking out of the crankcase and onto the transmission or clutch assembly.

What is involved in replacing a rear main seal?

Replacing a rear main seal typically requires removing the transmission and clutch assembly (on manual transmission vehicles) or the torque converter and driveshaft (on automatic transmission vehicles) to gain access to the seal.

Does this seal come with any hardware?

This Omix rear main crankshaft seal is sold individually and does not include any additional installation hardware. You will need to reuse existing hardware or source any necessary new components separately.
