Can someone explain how i know what a torsion bar looks like...or is located on a 97 4x4 blazer?

Answer 1

It looks like a 1 inch (or so) pipe or bar running parrallell to the frame just on the outside of the frame. Stick your head under the door and look at the frame and you will probably see it easily

Answer 2

It's a long, round bar that should run from your control arm to your frame.
