In theory, theory and practice are the same. In practice, they are different.
That's cool. Thanks for the pix

Thanks for the pic indeed! So the piece on the right is the shaft that terminates in the triangle, right? What's twisted on the one I have is the end of the shaft itself just below the triangle. I'll post a pic later.

I can't thank you guys enough. Everytime I post to RS I get such detailed and helpful responses. You guys are awesome

Yes, manual transfer case will have fewer issues but also no "shift on the fly", you should always stop to shift transfer case
Wut

I've never met a manual shift t-case that you can't shift on the fly. Especially in a Ranger, 2H->4H or vise versa is totally fine while moving. Going into 4L requires a stop no matter what.

You "can" you just "shouldn't", its different but similar to shifting a manual trans without the clutch, you "can" you just "shouldn't"

If front hubs are locked then in theory there is no shaft speed difference for the chain drive and main shaft so no wear shifting from 2WD to 4high and back

I'm copying this directly from the 1996 Ranger owner's manual:

To shift from 2H to 4H: Stop the vehicle and engage the manual locking hubs by turning both hub lock selector knobs clockwise to the LOCK position. Move the transfer case shift lever straight back to the 4H position. After both hubs have been turned to the LOCK position, shifts between 2H and 4H (or 4H to 2H) may take place at any speed.

Whether or not doing that causes more wear is debatable, but I have been doing it in various makes and models with both chain and gear driven transfer cases and have never seen a failure related to that. Besides, the 1350/54 manual shift and electric shift are so similar internally that if it's OK for an electric motor to do it, it's OK for a human to do it... it's a matter of the same pieces moving back and forth inside either t-case, the only difference is pushing a button vs pulling a lever.

Yes, as said you "can", if front hubs are locked
Not sure about the "any speed" thing, I thought there was an under 50mph recommendation
But Ford always knows best............:)

The electric shift does use a clutch, but that was probably for the Auto hubs as they would be unlocked before shifting to 4H

My credo
get outta my way, I'm falling!
right. the drivetrain needs to be brought up to speed before the auto hubs engage.
minor addition, the live front hubs from late 2000 on don't have that clutch in the electronic T-case.
