Do you think it could be the u-bolts are loose, cause the left springs are always shifting around making that annoying pop noise, but i don't think the axle noise and the loose spring are related.
front axle rebuild went wrong!

or worn shackle and pin bushings?

Ok, i have the video i promised and it seems like it has got worse 
I just recently added the aals in the rear and it's great, fixed the stance of the truck, however, while i was fixing the e-brake and changing the gear oil, i decided to drive the truck on pavment in 4wd, with hubs locked, but no rear driveshaft installed. It now vibrates vigurously in 4hi upon acceleration and makes bad noises. Does the same in 4lo. It makes the metallic noise upon accelaration and while braking heavily in gear.

Sean's front driveshaft has a DC at each end: transfercase and third member. It has probably what 4-6" of lift with no cut and turn. I'm inclined to think this is due to the driveshaft..assuming all else is well inside the axle.
Did it make the noise before you replaced the axle seals?

Ok the side of the c joint that goes into the 3rd is not flat, it doesn't mount to the t case because it has a circular metal "seal" sticking out that doesn't allow it to seat properly on the tcase, but i was atleast able to get 3 of the 4 screws half way tight. The other side does bolt up to the third just fine, in 4wd it no longer makes the noise anywhere near the volume it was doing before. Very, very quiet, even under load, at some points i couldn't hear it. So i beleive it is the joints on the shaft or is it the angle that it is at? Do yall think a new dshaft is in order or should i rebuild the old one? Sorry for the long description and thanks to everyones suggestions.

Can you post up some clear pictures of this? I am having a hard time following what you are saying.
Seems he has miss/matched yokes.... just by looking at the video the drive line has some wobble and has hard spots in the rotation..... I would at least try lifting the pinion angle up about 6* and see what happens......
You mean placing the floor jack under the third member assembly of the diff and rotating it up by jacking it up? Leaving the axle assembly on the jack stand of course.

Yes, i do agree, the pinion angle is horrible, probably what caused the premature ware in the shaft. Could it be that the noise is caused by the harsh angle which is putting an increased amount of stress on the u joints in the shaft? Do i need shims for this? I ask this because my springs already have 4 shims in each one of them.
Once my heep had a bad trans mount causing the front drive to barely shift, just enough for it to tap the skid plate, it sounded identical to what yours sounds like, especially on inclines or when the drive train was under load...
I hope you mean 4 degree shims. Is there any way the shims are backwards?
that would most certainly give you the horrible angle you speak of.
