Hello all,

Quick question from the drive shaft tech who has been working on my rear drive shaft. Which way does the drive shaft go back in? Obviously, I'm certainly concerned about the competency of this guy at this point, but for simplicity's sake, does the end with the slip yolk go toward the transfer case side or the third member side?

Thanks,
Jay

P.S. I've searched, but couldn't find what I was looking for.
 
Here is the 1994 FSM shot of the "propeller shafts": Looks like the "sleeve yoke" (or the "slip yoke") is to the 3rd member on the front and to the xfer on the rear.

The DC shaft is custom and should be installed as recommended by the manufacture, most of the time it's DC joint on transfer end for our application.

Here is a poor quality pic from the FSM, the slip yolks are #2 and front of the truck is to the left.

The slip yolks both go towards the front. The front is on the diff end and the rear on the transfer end.

glad you said that....i was starting to thinnk the FSM was wrong ;p
 
SEems like this is different from rig to rig. My understanding has been to follow the FSM as pictured above (as well as following the in-phase/out-of-phase rules too).

That said, I check out Doc's rig and on his front DS (IIRC) his slip yoke is to the xfer case side.

Also, from my understanding, the DC driveshafts generally have their DC to the xfer case side in both front and rear instances.

Anyway, this seems to be something that might be tweakable. I understand the necessity of have DC driveshafts at the xfer end (generally, this is where the most strain on lifted vehicles occurs).

I wonder if I change orientation, will vibrations be eliminated? Good little experiment to try out.

Any thoughts on this from drive line experts here?

Thanks.

The DC driveshaft is situated with the DC end towards the T-case on 80's because that's where the angle is. Usually when using a DC driveshaft on an 80, the axle end is a fairly straight shot.

It's possible someone swapped ends on Doc's rig at some time in it's life. If you took it off without paying attention and used the rear as an example, you'd probably end up putting the slip yoke at the T-case end. I can't see what it could hurt, but I'm not a Toyota engineer either.
I considered putting the slip yoke towards the axle on the rear driveshaft for clearance, but decided the grease nipple would suffer. :D

I changed it from 'zerk' just for that reaction!
