Update again,

Went back to the shop and put my car back on the lift and started to retighten some bolts thinking that stuff may have shifted. I looked at the two large bolts that go into the back of the differential and the rubber mount was cracked all around both of the bolts. I think this may be the problem, in the low gears the torque comes on really quick and this causes the driveline to flex a bit and make the rattle noise. I'm trying to find a part number but no luck as of yet. Could someone point me in the right direction? It seems with the car being 11 years old and being in Guam for 2 years all the rubber bits are ready to be replaced. My front right control arm makes a noise when I'm backing up and tap the brakes so I think that side is going out now.

If anyone known the part number for the differential mount/bushing could they possibly provide it?
