and get the stainless ball socket tie rod ends to replace the orginal IH ones. It makes the steering much easier. Also check the wheel bearings since its wandering it may have loose or worn wheel bearings too. There is an adjustment screw on the steering box to take up some of the play in it. Also check the center 90 degree lever that connects the steering drag link to the tie rods. Some of the looseness can be there too. Bill
BTW; It pays to have extra parts for our 154's inhouse too. I have more than a complete int154 in parts on the shelves. I have extra cub cadet parts inhouse too. Hamiltonbobscubs on ebay is were i got all the used parts. I like when its a quick repair when I already have the parts inhouse. Then i just replace them again. Just don't forget to reorder. I'm also starting to do this with fcub parts too. If were going to use and work them remember these are well beyond there years now and things are wearing out.
I can't say anything bad about the IH equipment of yesteryear when they will still outlast the new machines of today. The new lawn mowers look cheap in quality. I think my older IH stuff will still be running when the newer stuff is long gone.
