Same thing I had. Those Adjusters are a PITA.
Best thing to do: jack up the car, leave the wheels on.
Put a socket with an extention over the 2 loosened nuts of the
adjuster.
Now, you can either push the socket up with the extension, or put a jack with a piece of wood under the socket and jack it up, and then fasten it. Repeat for the other one.
Like I said.....PITA
