i have ran into 2 issues in these vehicles---if it binds while sitting still also, check the steering shaft, i have found the u-joints in the shaft tighten up and binds dangerously tight---if they are free, sounds like you may have a steering box issue or restriction in a line---hope this was helpful!!
