Check the motor mounts, happened to me with a 77 impala, same motor same problem. Could also be cv axles

Since vibes occurring only in 4x4 mode we ought to be looking at second transmission section. Eg cv joints, drive shafts , if we have file example bad joint, bush, bent shaft we can get this effect. Even mounts can allow vibration to occur if defective, a decent mechanic for that marque such as a main dealer can use a rolling road etc and check it out plus very good chance of solution.

NO, if its a CV Joint. It will vibrate all the time regardless since it is always turning. Some trucks either use the transfer case to engage things or a encoder motor to engage the axle but the axle itself is attached to the wheel & is always turning My first thing I would do is check the tires with a road force. But I would have to drive it. Some things you can tell how the vibration is to know where to look for. But I would lean on wheels first, yes I know you said they were balanced but I don't by what other people tell me unless I see for myself & I have done it to make sure it is correct. Next I would look at the front driveshaft but again, I would have liked to drove this truck to feel this vibration which would be a little more helpful
