mystery squeak under load

Need a little help here - don't want to go replacing stuff until it's fixed. Here's the problem - I get a squeak whenever I make my 77 CJ go using the engine, in other words when coasting or braking it doesn't squeak (its an automatic;q-trak). Seems to be speed related (pitch changes with speed though when I get past 45 can't hear it most likely because of road noise) Can't really tell where its coming from at first I thought bearings (even though braking didn't make the squeak go away) so re packed just to make sure. no help. now thinking u-joints-- but before replacing all four and two in the axle wanted to get some suggestions of other things it might be or how to narrow it down to which u-joint. any suggestions?

If you dont have the hubs locked in and it makes this noise it has to be the rear drive shaft.

'preciate the fast reply - it's full time 4-wheel drive Q-Trak transfer case. No hubs and from what I understand I'll kill the cones in the Q-trak if I remove either drive shaft and try to run in 2-wheel.
