Can't comment on weather or not to use with power steering, but Danchuk has instructions on their website that are pretty clear. I bought the kit from them, haven't put it on yet but I removed the old idler arm bushings and let me tell you they are a pain. Took the one in the center link out with an air chisel but the one in the idler arm itself I had to burn the rubber out and then use a carbide burr to cut the sleeve in half....and then still use the air chisel.
