Glad I'm not the only one going through it!

I drove the truck two days in a row, unloaded, this weekend. I locked the hubs in, but left it in 2WD. No noise...at any speed, or over any bumps. Interesting. It won't cost me anything but time to inspect the front wheel bearings...I'm wondering if the driver's side bearing is loose/bad and is allowing the splines on the end of the axle shaft to contact the hub or something else in the spindle area, and now that the hub is locked it, the shaft is supported from the end and not making any noise.

Odog, thanks for the FYI. If it has to come out, I'll be inspecting everything. I suspect something might be out of whack in the adapter as well, when coasting there is a faint clunkclunkclunk sound coming from that general vicinity.
