I am thinking about getting rid of this stupid varible ratio factory steering box. I changed that steering wheel possition sensor and I think I may have to change the power steering pump or that varible rate flow valve on the pump. it works ok but everything has 160k on it so things are wearing out. What kind of problems am I loking at if go with an AGR pump and AGR 12/1 ratio quick steer/ steering box. I know the thing will be sesitive at highway speed but I am kind of used to that anyway. I got this 98 Tahoe 4dr 2wd a couple of moths back and I know I am basicaly reinventing the wheel on it but it is my tow vehicle for my boat and the damn steering box seems to not be very responsive at highway speed and it is strange to me. Let me know if any of you have done it or see potential pro's and cons about doing this. Thanks
