Strange vibration

So when I am backing up/ in between switching gears I have a very loud vibration from the middle/back end of my car. I'm thinking it is a transmission mount but I haven't had a chance to get under it today. Anyone experience this?

It has happened when turning, and decelerating but it mainly happens when I'm in reverse letting off the clutch and giving it some gas. I read something a minute ago, someone with this same problem and their driveshaft ended up being loose so I'll get under it tomorrow and see if that may be the problem.

Differential fluid. Probably just needs changing.

I had kind of a metallic grind/vibration when going around turns sharply. I thought my diff was bad, changed out the fluid and that was it.
If that doesn't do it or if my symptom doesn't match urs then get a friend to replicate the symptom while you listen and watch.

Well I figured out it wasn't anything to serious... Both of my exhaust pipes were banging against the frame rail I was surprised those damn things created that much noise/ vibrations. And I just had my exhaust redone about a month ago... Looks like I'll be going back and getting that fixed for free. I was worried, because my differential does have a slow leak :/, going to be getting that fixed soon also.

Thats really easy to fix too, just open it up, scrape out all the old gasket and put on ATV and close it up (replace fluid obviously)
