Front driveshaft for 1999-2001 F-250/F-350 Super Duty and 2000-2003 Excursion with the 7.3L diesel and 4WD. Replaces YC3Z-4A376-EA and 938-305.
This is a complete front driveshaft assembly for the 7.3L Power Stroke Super Duty and Excursion. It replaces Ford 5C3Z-4A376-D, F81Z-4A376-MA and YC3Z-4A376-EA, and cross-references to Dorman 938-305 and 65-9303.
Listed fitment: 1999-2001 Ford F-250 Super Duty and F-350 Super Duty single rear wheel, 4WD with the 7.3L diesel, plus the 2000 (from 10/99) through 2003 Excursion 4WD with the 7.3L. Gas trucks, dual rear wheel F-350s and 2002-up Super Duty pickups are not on the list, so check the number on your old shaft.
Extended length is 45.7 in and compressed length is 41.6 in. The shaft is steel, painted, and balanced with the joints and slip yoke greased. On these heavy diesel trucks the front shaft commonly wears out at the slip yoke and joints, which shows up as a clunk when the hubs and transfer case engage or a vibration in 4WD.
Install: shift the transfer case to 2WD, mark the flanges, remove the U-joint straps or flange bolts at each end, and lower the shaft. Install the new shaft in the same phasing, torque to factory spec, and test in 4HI.
