Drive shaft failure doesn't seem to be that common, I would try a junk yard.

 

I was thinking that but they don't warranty any parts and I don't know what condition it is in

It's a driveshaft. There really isn't that much to it.

Replace the u-joints, that's a given, and you're good.

Or, take your existing driveshaft to a driveline shop and get it fixed.

 

The gears in the rear end are broke? Or the ears of the drive shaft are broke? Nothing can go bad on a driveshaft other than broken ears or bad ujoints either way it will be visible

 

the inside of the drive shaft..that's where the pop sound is coming from..I was under the truck when he looked at it

Can you post any pic's of this damage because there is nothing inside a drive shaft to break as dodgeramguy85 says the damage is on the ends.

Is it a 2 piece shaft is that it?

Post a pic or two please

 

The only thing to snap, crackle and pop under/back there is the diff with drive axles. Perhaps the wording is a little off.

OP, is it the rotating shaft you can see under the truck or is it in the rear axle where you can't see it rotate?

I suspect it's the differential and thus the concern of getting one at the scrap yard. We may find out soon enough!

The only thing inside a drive shaft will be card board or foam. Other than that nothing inside the shaft is broke. I would look a ujoints and inside the diff.
