1999-2004 Ford Super Duty F450 and F550 Trucks use the same outer axle shaft as their lighter duty F250/350 brothers, but the inner axle shafts are different.
The Achilles Heel of the 1999-2004 era Ford Super Duty front axle is the way the axle shaft is supported. The inboard end of the inner axle shaft is anchored in the differential, but most of the axle shaft weight is borne by a smallish needle bearing in the wheel hub and by the lockout hub. If the needle bearing runs out of grease, the bearing will quickly chew up the outer axle shaft before you start to hear grinding noises. We stock all the original equipment axle shaft small parts plus new inner and outer axle shafts for your 1999 to 2004 Ford Super Duty® Model 60 Front Axle.
