Cope sounds like the exact problem I had .Good news is it should be an easy fix .The pressure from the pump is mis-routed through the steering gear box making the wheel turn all by itself.little hard to get to with the manifold in the way .Just make sure to takle it when the engine is cooled down. I can't remember exactly how I fixed it this was like twenty years ago, Dang! I just know I had to unbolt the top of the steering box and re-align everything .There's like 3 bolts holding the cover on that the hoses connect to and 3 o-rings underneath there is also a valve assembly that extends into the unit from the pressure hose I think that's where the problem is. Hope that helps .I'd leave the bumperettes .If you remove them there will most likely be much shinier chrome underneath so it will be obvious something's missing .I didn't used to like all the excess trim but items like that make your car a bit more individual. But it's your car build it how you like! If you do take em off sell em to Me LOL !
