Transfer case questions
This is for this is for the truck in my signature. Short bed, std cab.
1) I see the transfer case is connected to the transmission via an extension. I am working under the truck and don't have a lift. What's the best way to remove the transfer case, which side of the transmission extension?
2) (long term question) am I able to upgrade this transfer case to one that I can shift on the fly, like the newer push-button transfer cases? Any way to adapt this?
Thanks

1) I'm 95% sure the "extension" is the 4WD trans tail shaft housing and you remove the t.case at the back of it, leaving the tail shaft with the trans.
2) If you have manual hubs you can shift any t.case on the fly. If you think you might want 4WD lock the hubs before you start out. Then you can shift back and forth between 2-hi and 4-hi pretty much any time you want. It's best not to do it when you are in a relatively tight turn, and you do NOT want to be spinning your back tires when shifting into 4WD, but otherwise no real limits.
If you have auto hubs (and plan on keeping them), I don't think the lever-shift t.cases can be shifted into 4WD while moving, unless the hubs are already locked. There were push-button t.cases used in a lot of F-150s in the '90s. Those should be an easy swap mechanically. You might have to get a little creative with the wiring, but that shouldn't be too hard either.

You can shift on the fly between 2H and 4H regardless of the hub style. As Nothing Special mentions, don't do it in tight turns or with the read wheels spinning. Just ease of the throttle at the moment you shift to remove load from the drive train, then ease back on the throttle. No need to upgrade, you've already go what you need.

Transfer case failure
I do not want to hijack this thread but I can not figure out how to start a new thread of my own!
But my transfer case just literally came apart and I want to upload some pics and see if anyone has ever seen it before?
Please advise me how to start a new thread?

Just my opinion but if you have the auto hubs change to manual ones. I recently had to drive 100 or so miles with one side half engaged .And I think the owners manual says something about 55 mph is the max speed to go to 4Hi.
