Pulled out parts axle apart. Needed a better spindle but found out it had been updated to u-joint axles. (top) Our axle we are building had the Bendix type axle. (Bottom) The donor set up also had these locking hubs in great condition the u-joint style requires a c-clip on the hub, this c-clip is removed to run the locking hubs The Bendix style axles do not need c-clips. Anyone with any experience on these? The spindle with the u-joint axles has a dinged up bushing the side with the Bendix style does not these bushings are being replaced.
