The other day I noticed at low speed i was getting a slight rumble. This morning it was progressively worse. At around 25 it start banging from the rear it feels, then about 30 it just goes away. It does this both speeding up and slowing right around 25 to 30. Doesn't seem to matter if I'm on the accelerator or braking so I don't think its rotors but maybe driveline related. I drove to work and I guess after it heated up the problem stopped. Any ideas? I know I'm stretching to find a solution but just trying to get an idea of what to look for.

Edit because I forgot jeep info dang it

It is extremely cold here which I hope has something to do with it. Left for lunch a minute ago and it didn't do it so we'll see.

Without knowing year, mileage etc kind of hard to say
but...
check rear ujoints ( they may feel tight but will be worn out, my first set went at 55,000)
Rear boot on the front driveshaft check it, may have to replace the CV, easy/cheap to do
Start there and let us know
