Really that's weird I had my transmission rebuilt like 4 or 5 months ago so I don't know if the bolts came loose or what but I did climb under the car and when I raised it up I noticed that my exhaust was touching the driveshaft I don't know if that could cause it. But I have had te exhaust on for like 4 years now and it never made the noise so I don't know and I tried prying on the u joints and they didn't move to much it wiggled a little bit and I spun the wheels on the back and didn't hear any weird noises I spun them real quick then stopped them but no strange noises
