transfer case from a f150
88 f350 Tcase wont stay in 2wd or 4hi so im gpnna change it. My f150 case is same number borg 1356. Local parts yards say they wont work but only difference i see is the tailshaft housing. Can i just swap housings on a 150? Plenty of 150 tcases around. Is input shaft and output shaft same? Id think a 1356 is a 1356 no matter truck just slip shaft or not and size of slip shaft maybe.

Everything for the shifter, mounting, and connections should work, but the tailhousing is different. The F150 used a full slip yoke, the Bronco had a fixed yoke, and the F350 had a sort of hybrid thing, like a short slip yoke. The driveshaft had a slip joint behind the center support bearing, but then the front end just slipped in to the back of the case. I'm not sure if you will run into any sort of interference running the F150 case, I don't know how much longer the tailhousing is.
Check your linkage, and the case mounting to make sure nothing is loose. If it's all good, you might be able to swap the shift forks between the two cases or just get new ones for the F350 case.

Hmmm.. I'm have to take a closer look at the F350 parts truck I have, I thought the tailhousing would be the same? Don't think it has a support bearing, but maybe the crew cabs do (mines is regular cab).
The internals should swap and case halves if needed. Check the shift linkage, its possibly different. I rebuilt one out of something and the shift shaft was different externally, but the same inside. Swapped it with the one I was taking out and it worked find.
As Ford Six mentioned, the shift forks will swap and might be your only problem. These are easy to rebuild, somewhere I have a link to decent writeup.

All looks the same to me. Same shift linkage. My 350 is a short wheelbase. Only diff i coud see is it looked liked the slip shaft was bigger on ton truck. But thats just eyeballing it.

smae size got the calipers out. tor down the case and the bushings are toast and eat into the fork. everything i can come up with is if the case dont have a tailshaft for a speedo gear then it wont have a hole for the ball bearing that holds the gear. You just wont have a working speedo but you will have a working truck. If i find another im gonna pull it apart to change bushings so i can chang shafts at that point. in theory.

Called mid west trans and they told me to be sure of the endplay on the input shaft. There are thrust washers on that shaft that will wear allowing the planetary gears to shift increasing the problem. (Sound it makes like your trying to put it in 4low while the trucks moving when just coasting get on he fuel and it quits). Guy told me input shaft endplay should be about 20thousandts.
