Hitch in the giddy up

Lately my 2006 Tacoma has a hitch. When driving I get a momentary bump/ thump, almost like hitting a pothole or rough pavement, only there isn't anything wrong with the street.

A month ago I had a lock up where the truck wouldn't go forward or backward. The engine revved up when I stepped on the gas, but no motion. I turned it off, walked around the truck, and turned it on again and drove off no problems. Dealer that looked at it said they saw nothing. wrong.

Now I've got these momentary incidents when it seems something is binding or stopping the rear end from moving properly. Some trips it never happens. Others it will happen 2-3 times, and then nothing. I don't want the whole thing to lock up again like it did at the stop sign previously.

Any ideas what to tell them to specifically look for when it goes back to the shop again?

 

sounds like a parking brake draggin maybe?
