What to do??
My rear end went out in the truck in my sig. Pinion gear was chewed on pretty good. Should I rebuild this rear end or just swap in a new one. Looking for the least expensive option!!! Any help is appreciated.

If the housing is still good I would rebuild it. Is is a 70 or 80 diff? They are not cheap I rebuilt many of them. Make sure the carrier bearing race didn't spin in the housing, if they did the housing is no good. They are not the easiest diff's to rebuid since all adjustments are done using shims. It's trial and error sometimes to get everything dialed in. You might want to try wrecking yards first, might have to look at quite a few to find a good one. That would be the cheapest way to go. Good Luck

Thanks guys. Called around yesterday, first guy wanted $1000, next $1500, next $500. Think I can find one cheaper than $500 or should I snag that one.

I would think that with any junkyard unit, you would want to replace the bearings before you installed it in your truck anyway. As mentioned the D70 commonly spins the left carrier bearing race in the housing, causing damage, and you may have that issue with any used unit that you find. If it were mine, I would either rebuild my existing one, or upgrade to a Dana 80, which has larger, stronger bearings.

If the $500 axle is still installed in a truck at the yard and has reasonable milage (<150,000) I would jump on it. I don't think you can buy the parts to rebuild for less than $500. You could get some money for your old one as well to recoup some cost.

All the second gen 2500 trucks with a manual transmission came with a Dana 80. Not sure of the specifics, but I think it would be a direct swap. To the best of my knowledge, the driveshaft, u-joint, and springs are the same. Not sure about e-brake cables, but that's minor.
