Here is the first of many silly questions as I begin re-assembly. Which direction do the prop shafts go? Long side at the pumpkin or transfercase? Does it matter? When I took them off two years ago the short female yoke ends were at the transfer case side, but this looks different from a picture in one of my manuals?

My manual shows the stubbies towards the transfer case, long shafts towards the pumpkins...

Hingsing, Mine were installed the same as yours with the slip joints at the transfer case end. Although I don't believe it to be critical I would reinstall the same way as to keep the joints up high away from the elements(mud,water,etc.).

The slip yokes ALWAYS go on the DRIVER end, or output yokes of the transfer case. The other or DRIVEN end attaches to the component that is being driven, in this case that is the differential yokes. The same is true on the intermediate shaft, the slip yoke attaches to the transmission ouput & the splined stub shaft to the transfer input.

Thanks again

I have always put the slips up next to the transfer to get them out of the drit and water, but then I am a old jeep man and what do I know?? ....Phil in Mt

Sorry - but I'm a bit slow today Just so that I have this right - the splined end (the shaft) is always the driven end, and the socketed (I know - wrong word) end is the driver? I'm such a visual learner ...

OK - now that I have my underwear on backwards.....

Drive Splined Shaft - long shaft with grooves - male shaft(3 diff lengths)
Slip Yoke - short stubby - female spline (3 all the same)

Slip Yokes - one connects to transmission output, one connects to RWD transfer case, one connects to FWD transfer case. I think these are the same part used in 3 locations looking at the manual.

Drive Shaft - long one connects to RWD pumpkin, med length one connects to FWD pumpkin, and the real short one attaches to the transfer case aimed at the transmission.

Yes?

If I'm reading you correctly, this sounds right.

To add to this subject driveshaft alignment is important also, the slip yoke if removed, must go back on the same way so the u joint yokes on each end are inline to each other. Some slip yokes are keyed to only go that way, others are not allowing incorrect alignment and resulting in bad driveline vibration.

All original M37 drive shafts have keyed splines, so unless you are dealing with a non-original replacement, you can't go wrong.
