Just a note on a "steering issue" I found today... Check the bolts on the two brackets that hold the power steering cylinder to the front axle. One is on the left side of the piston, one is on the right side. They are circular, the piston goes through them and they bolt to the front axle with two bolts each. The driver's side on mine was ready to fall off the tractor; the other was OK but not very tight. In another week the bracket would have come off and probably damaged the piston or the other bracket.
Something to be said about going over every bolt with a wrench....
