Driveshaft on my 91 150 snapped so gonna pull one from boneyard to swap it out wondering if anyone knows if a driveshaft from a 4x4 will fit 2 wheel drive

 

No, the transfer case on a 4x4 adds about a foot to the back of the transmission so the 4x4 shaft is that much shorter.

 

Any idea which ones would work I have 91 xlt larait with 8ft bed 5.0 automatic

 

There are two different four speed overdrive transmission available on this vintage truck, AOD and E4OD. One is a mechanical OD trans. and the other is electronic OD. They are different lengths therefore the drive shafts are going to be different lengths and perhaps the yoke as well. I suspect you have the AOD since that is the more common behind a 5L truck.

I would suspect a driveshaft on a 1987 to ~1993 F150 with an AOD and same bed length/cab should work. 1994 Ford started using the 4R70W behind the 5L trucks. As well as the same sprinkling of E4ODs.

 

What's my easiest way to tell which trans it is

 

Driver side Door jamb sticker: Trans Code T is an AOD. Trans Code E is an E4OD.


Item 3 below:



You can also count the number of bolts on the transmission pan. 14 bolts = AOD. 20 bolts = E4OD

 

Sweet thanks for the help

 

The easiest way to make sure you get the correct drive shaft is to take a tape measure with you to the junk yard.


You can determine your transmission by looking at the shape of the transmission itself, or by the shape of the pan. Do a search, it's pretty well covered...
