Question "Ker-thud!": Bearings or U-Joints?

I'm getting a; "ker-thud, ker-thud, ker-thud", when I take turns. It seems more intense on right turns. I can feel it through the steering. I've checked tie-rod ends & balljoints, & they're fine. Can anyone tell me how I can check if it's either bearings or the u-joints in the axleshafts? I've got new u-joints anyway, but I still wanna make sure I don't need bearings. Thanks!

By any chance are your front tires rubbing?

No. Actually, the very 1st thing I checked was the tires.

They're both on AUTO. That was the 2nd thing I checked. To tell you the truth, the driver's side hub is stuck in AUTO. Do you have a pointer for that?

The hubs are bad, I replaced mine on my excursion with regular lock outs, Saved 1-2 mpgs also.
Easy fix

It was, actually, the hubs! I had looked @ them yesterday & they were in the AUTO position. When I turned them to see if they moved, the driver's side hub just kept turning. So I put the front end up on jackstands & turned the l/f tire. Sure as crap, the driveshaft for the transfer case was turning. She was forever stuck in LOCK. I picked up some sweet WARN hubs that were sold in a set for $120 from the local autoparts store! I got 'em in & no more-"ker-thud"! Thanks for the help, guys!
