My Dad has a 9N. Runs good, but the steering aint good. The front tires will flop around enough, that they will toe-out too much to drive it. It looks to me, that the issue is with the steering arms where they come out of the "steering box". It is almost like one of the sectors jumped a tooth or something.

Any idea how hard, or expensive this would be to fix?

Are you sure it isn't excessive play in the drag links?

The tie rod ends are tight. It seems more steering box related.

I had hoped to look at it today(it's 35 miles away), but got postponed. Hopefully Thursday.

as you know, the 9n/2n has a completely different steering setup than the 8n.

if one of your side arm gears has jumped on the steering gear.. then you are in for pulling the trsanny top as that is apart of the stering box

still.. at this point.. you have not much choice.

here's a parts list to go with the diagram:

Guessing that would be the case.
Aint no good with no steering(the tires move around too much to drive it, besides maybe on my trailer.

as you know, the 9n/2n has a completely different steering setup than the 8n.

if one of your side arm gears has jumped on the steering gear.. then you are in for pulling the trsanny top as that is apart of the stering box

still.. at this point.. you have not much choice.

good luck.

aside from the inconvienience of pulling the trans top.. it's a pretty cut and chase clean steering system. not much room for wear though.. ie.. not many adjustments. thus parts replacement will be neede dif something is excessively worn.
