The rear main seal stays stationary while its sealing lip rides on the rotating crankshaft, which helps retain engine oil. Signs this part may need replacing include oil dripping near the joint between the engine and transmission, oil residue on the bellhousing, and a steadily dropping oil level. Other nearby gaskets can leak too, so confirm the source before replacing. Reaching the seal generally requires separating the engine from the transmission. Consult the vehicle service information for the correct procedure, the correct fasteners, and whether they may be reused.
