SEAL - REAR MAIN (Toyota TY1138131720)

TY1138131720: A worn rear main seal can allow oil to seep past the crankshaft, leading to visible drips and potential fluid loss. This aftermarket replacement part references the Toyota catalog number TY1138131720. The seal type creates a stationary barrier around a rotating shaft to contain lubricant. Over time, the sealing lip hardens or cracks, resulting in a slow leak that may worsen with temperature changes. During a routine service interval, a technician might notice oil residue near the bell housing area. The item ships at approximately 0.174 pounds. Verify the serial number or application, then call (562) 693-7748.
