I have a frankensteined 2000 mustang. It had a rear end swap and now the rear end seems like its moving when I shift/decellerate/brake/etc. It also has a popping sound i need help figuring out what this is, do I need a new rear axle? It was swaped with a nice 3.73 I don't hear any nooise coming from the pumpkin so I think the pumpkin is okay but could it be engine/tranny, or rear axle mounts?

How about the bushings in the mounts? Are they all tight? When do you get the popping sound? Over and over or when you stop, or turn or take off?

Its when I turn/take off/stop. I don't mean burnin rubber either it does it when you baby it.

It doesn't take a very loose bolt to do that either. A bolt could seem tight and shift with the force of movement. Check all the joints too.
