Sounds odd...Check the driveline for excessive movement and watch carefully when it's going into and out of gear. If you see any excessive movement in the differential yoke, likely there is a lot of gear lash inside. Also make sure all differential mounts are secure and that no bushings are worn. Likely if you are looking at them and someone puts it into gear, you will see a shift there if they are worn or loose. With difficult noises, I often use a long pipe, bar etc and actually place it against different olcations to narrow down the noise source.
Noise while loaded is different and can come from a bad internal shaft bushing in the transmission, a cracked flywheel or possibly a bad main or rod bearing.
Since you removed the transfer case, I'll assume you checked the universal joints for binding and excess play so that should be a non-issue. I'd also check front axle joints as well just to make sure there is nothing going on up there (sounds often travel, which is why looking is better than listening)

Theres play in my front drive shaft. I dont know if its the u joint or the rear end going into the transfer case. what is the most in expensive way to fix problem. problem is when braking accasionally feel...

the cheapest way would be to remove the front driveshaft I guess... This will give you opportunity to inspect the Ujoints too!
If it is only a Ujoint... you can replace the Ujoint and shaft when you have the money to do so...

loosen all the engine and trans mounts and the exhasust head pipe pipes from the exh manifolds, then shift the trans from park to reverse a few times and then to nuetral, shut off the engine and see if that helps.

Truck makes a clunk when intially put into gear

Look for dust like rust color at either U-joint, my guess is it's time to change at least one, but if I did one, I'd do other too.
