Transfer case linkage
I have a 90 F-250 4x4 automatic transmission. 140,000 miles. The linkage bar between the shifter on the floor where it goes through the floor linking it to the transfer case. Flat bar approx 1/16"×3/4" wide and 12" long. Plastic bushings on each end. It seems like it's a half inch too short. I replaced the bushings and it's the same story.
. I'm kinda stumped. It's original stuff and half inch is a lot of wear with no signs of wear like sloppy gears. It seems that the solution would be to cut it and add a half inch to it and it should work.
. But this just seems like too much wear. Any suggestions n thanks folks

Well if it is all original, something is out of whack and needs further investigation. You shouldn't ever need to shorten or lengthen that bar, so something else is happening. Is the case in the right range compared to the shifter?

I think there were two different bars. one for each transfer case. Might be a f150, and a f2/350 difference as well. I could be wrong but I recall there being a couple different links in that area.

The ZF and M5OD are shorter than the E4OD but the same length as each other and if you mount the shifter in the same spot and slap the same case behind them you'll need different length linkages.
Cab bushings and engine mounts and whatnot have nothing to do with this as all parts in this case are mounted to the side of the transmission and wouldn't be effected by that.
Regardless, it wouldn't exactly be hard for OP to cobble together an adjustable replacement for what he has.

I forgot to ask about this comment.
My question is have you owned this truck its whole life? Or you bought this truck used and the link is what was on it when you bought it? If you bought it this way did the shifter work when bought and just not it has quit? or you just now found it does not work correct?

Thanks folks. I have owned the truck for 10 years. Tracy rebuild 9 years, 15,000 miles ago work truck. C-6 with overdrive. I can not see any wear or rust bleeding from any mounts. No noise detected in anything.
The only connection between the floor shift lever and the body is where the shifter connects to the floor. Kinda spitballing here but if the cab did slide forward, this could be a cause. Why it is now short.
What say all, and thanks for helping me think this out. My gut feeling is that the cab slipped forward. Body is rusted. I know I feel better about extending the linkage bar after this discussion. And that would fix that problem. Actually truck is in great ok shape except rust

If the cab slid that much, wouldn't the front of the doors be jamming up on the fenders? If the door/fender gap is good, then the cab probably did not slip forward. I would check shifter alignment on both floor and transfer case. I'm wondering if during removal, something got jogged out of alignment?

i really can't see that being the case as he has owned the truck for 15 years, and the transfer case shifter worked fine until it stopped working.

Maybe I've been working too many 14 hour shifts?
Quote : I have owned the truck for 10 years. Tracy rebuild 9 years, 15,000 miles ago work truck. : End
Did it work after rebuild? IF unsure or no was it rebuilt at a shop / garage ? if so maybe they installed wrong link when reinstalling trans?
If it work last week and this week it no longer works... What does not work? Maybe broken/ damaged shift fork inside transfer case, roll pin on fork to shift rod damaged, broken?
