Shop now for Axle Shafts and Universal Joints to fit 1966-1971 Ford F-100 Trucks with Dana 44 Open Knuckle Front Axles.
From 1966 through 1972 Ford F100 1/2 ton axle shafts used Spicer 1310WJ series axle universal joints with 1-1/16" diameter cups. Starting in the 1973 model year, Ford beefed up the axle shaft u-joint for the F100 to the more durable Spicer 1350WJ size which has 1-3/16" diameter cups.
1966-1972 F- 100: Axle U-Joint Cup Size is 1-1/16".
1973-1979 F-100/F-150 and 1978-1979 Bronco: Axle U-Joint Cup Size is 1-3/16"
For the early, small 1-1/16" u-joint, we have only one non-greaseable choice as the small cross will lose too much strength if drilled for lube channels.
