• Description:

  This genuine Ford crankshaft thrust bearing controls crankshaft end play on the 5.0L Coyote V8 in 2018-2025 F-150 and Mustang, cataloged by Ford as an engine crankshaft thrust washer under base number 6D309. It seats at the thrust main journal and takes the fore-and-aft axial load imposed on the crankshaft, most notably the clutch-release or torque-converter thrust load, holding the crank within the specified end-float window so timing-drive, seal, and bearing alignment stay correct. Technicians reach for this part during a bottom-end rebuild or when diagnosing excessive crankshaft end play, a thrust knock, or wear traced to prolonged clutch-pedal loading or oil contamination. Symptoms of a failing thrust bearing include a heavy intermittent knock, a crankshaft that walks fore and aft, and in severe cases interference with the flexplate or front seal. Measure end play with a dial indicator against the factory specification before and after installation, keep the running faces clean and oiled, and observe the correct orientation of the flanged surfaces. Choosing the genuine Ford thrust bearing preserves the exact flange thickness and material needed to keep end play in tolerance and protect the rotating assembly.

• Notes: Includes 1 Upper Bearing And 1 Lower Bearing.
• Applications: 5.0L.
