Hi guys I am new to this so please be patient, I reciently purchased my first 318 I t has 607 hours on it and looks great. It was a one owner. I changed all of the fluids and cleaned everything and when I drove it up to the gas station a few blocks away to get a feel for it I notice that the steering does not return to the same place everytime when you turn back to go g straight. It does seem to be pretty good as play, hardly any play in the wheel when the tractor is off settin in the garage. I checked the axel bolt tops and they seem very good so I do not know what to check for next. All I have ever had to mow and plow with before for 15 years has been my 140h3 so this power steering thing is new to me. Thanks for your time. Roger Q
