Getting the steering wheel back to center when driving straight is not hard, I had to do it on my 26AY after adding air suspension. There is a tutorial on how to do it in my other posts on handling issues, with a link, takes less than an hour. Only takes a wrench, crows foot pry bar, and a hammer. A shop will either tell you they can't do it or charge about $160. If you can't find the link PM me and I will hunt it up.
Found it, you can find the instructions for centering the wheel
