Pitman Arm nut problem
I am having a problem with my SD. The nut is loose and the lock washer spins. The nut appears tight but I would like to know what size the nut actually is. The truck is a F-350 with 6" of lift. I know this puts extra leverage on the shaft and obviously the arm should not loose. I am gonna buy some 3/4" drive sockets to tighten this nut but what size is it?

I believe the socket I used was a 1 5/16". I'm not at home at the moment, but I'm almost sure that is what it was.
ON EDIT: I believe you can also use a 32mm, but I kind of remember it being a tight fit.

Update
I just got a 1 5/16" socket and it appears to be a loose fit. I tried a breaker bar with a jack handle and it slipped. I don't want to round the corners off so I may have to try the 32mm mentioned earlier. I am trying to avoid replacing the box as I imagine it must be expensive and probably a pain to replace. I will probably go over the rest of the truck as well for tourque specs. The lift was installed by a seemingly intelligent guy but I am starting to question that.

Did you get a 6 point or 12 point socket? A 6 point would be a lot better. If the washer is that loose and nut is that tight I would be trying to get the nut off to see what's wrong, either you ran out or threads which would indicate some kind of pitman arm problem or the nut is stripped which needs to be repaired. I can not stress to you enough how important it is to fix this the right way.

Belive me, I realize how important this nut is. I would not want to loose steering in a 7000lb vehicle. It is currently not being driven til it is fixed as it is scary to drive with that much slop in it anyways. I believe it is a 12 point socket. I didn't even think about it until something was said. It was all the parts store had anyways so it was worth a shot.
