Cleaning up my T-18 out of a 1988 F-150, and noticed that it didn't look like what I expected at the output ( fixed yoke type with threads for a nut ), but the trans I have has a 12" extension housing which I learned is a slip type. it has splines and a machined hole in the center.. Dennys driveshaft has a listing for a bolt on yoke, but is the slip yoke the same? The breakdown for the T-18 has both style extension housings, but only the 1 yoke is shown..

bump.. trans cleaned up decent, or at least most of the thick stuff scraped off and I can read the ID tag and casting numbers. I think the donors truck engine blew an oil seal, as it was pretty well covered, but none of it appeared to come out of the trans

I have never seen a yoke which would work either way.

Most bolton yokes are short. All slip yokes are long.

that's what concerned me. just the breakdown I found, which looks like it came right from B/W only shows the 1 yoke which I found odd.. I guess I could use a bolt on yoke, slip it on and put a 2 peice driveshaft in with a collapsable rear section and that would work, but it wouldn't be right..
I'm going to go to the junkyard I got the trans from and see if they can trace the driveshaft from it or 1 that will work. The trans was a shelved unit, so the truck is long gone, but hopefully they can cross parts removed from it togther.

Google PowerTrain Part# 3304-281.

Some 435 and T18/T19 Had a yoke that Looked like a slip but it was a bolt on. The Spicer version of that yoke has been discontinued for quite some time.

Found it thru northern driveline http://www.northerndrivetrain.com/pr...1330-2805.html That looks like the bolt on yoke. I have the junkyard looking for a yoke. They don't have any invintoried but they have a few drums of yokes, and another trans to test on..

This is the yoke that I think looks like a slip yoke but is bolt on. doesent look like the #3304-281. http://www.dennysdriveshaft.com/p105..._bolt_on_.html

What can I do in this case? I cant even verify it is a slip yoke, but I dont have threads for a nut on the output for a bolt on.

[matt167]

If I cant find the right yoke, could I get the yoke from Dennys driveshaft, and a driveshaft/ carrier bearing from a donor F-150 with a slip joint driveshaft in the rear and 'hold' the yoke in with the carrier bearing? or is that not kosher?

[matt167]

how about this yoke? http://www.ebay.com/itm/FORD-28-spli...item53da7d56c4

spline diamater lines up with the info posted by Northern driveline, spline count and ground hub diamater ( which I assume is the 'finished' surface ) are all the same... Can cross it back to Northern driveline and it looks the same also
