I'm sure this is covered somewhere, but I'm striking out searching. Basically the passenger side front axle (whether hubs are locked or not) makes a rattling sound mostly over bumps. Clackety-clack, clackety-clack like a train, but random rattling. No pattern.

I pulled the Warn locking hubs I recently installed to have a look in there but all I can see is the slop in the spindle up-and-down, or side-to-side as you sit looking directly at the wheel and move the spindle around (see photo). The repair manual makes reference to an "axle bearing" under the Front Drive Axle section but there is no diagram. Is that referring to the wheel bearing (the one you tighten to 43 ft/lb, then loosen and retighten to 18ft/lb) or is there some type of actual axle bearing for the half shaft? Do I have a worn out axle? Bushing? Bearing?

There is a certain small amount of slop in both axles along the axis of the axle - getting under the van and pushing the axle away from the wheel and toward the front diff, and vice versa. But I think I read here that's normal.

Forgive my ignorance of the 4WD.IMG_5773.jpg
