update, obviously it needs to go back to the shop. unfortunately they are already closed. So i will be hauling it there on trailer monday. I just put it back up on the lift and ran it without any weight on the tires. it didnt make a sound at all. but when it is lifted and lowered it would make the popping sound. but it did not seem to be coming from the axles, it even happened when i lifted it and turned the drive shaft, while holding the drive shaft and lowering it and raising it i was able to feel a little click/pop when i heard it. it was very weird though, it was very hard to trace where it was coming from and each time seemed like it was coming from different locations. which to me would seem as if it was coming from inside the differential and just hearing it all around.
