Need some 4WD help for this storm!

Hey guys I was hoping you could help me out since I am in the middle of a snow storm right now.

I haven't used my 4wd since I got the jeep though once I got it I realized that the lockers were on while I was driving around so I turned that off; other than that I haven't touched it. Like a fool I never checked when I got the Jeep if it works.

Inside my jeep is a chevy 327 with a TH350 mated to what I assume is the Dana 300. Now I am confused on procedure for shifting through 4wd since this is my first 4wd vehicle. My shifter goes as follows top to bottom:

4L
N
2H
4H

When shifting into 4H I would want to have my lockers locked of course and be moving under 20MPH for good measure, then shift the jeep into neutral and pull down on the transfer case shifter and put it into 4Hi. After that I shift the jeep back to drive and go. What if I am stuck and can't move, do I just put the jeep in neutral and pull the shifter into 4Hi.

I feel more often than not I get stuck in a parking lot from having my jeep in one spot during a storm.

I assume the same procedure backwards to shift back into 2Hi.

Now if I want to shift into 4Lo do I need to stop at Neutral on the transfer case or can I just push the shifter through?


Hopefully you guys can offer some insight, I'd like to find out if my 4wd even works in the jeep and now is a great time to test it.

I am assuming that by saying "lockers", you actually mean the locking hub mechanism. Commonly referred to as "locking in the hubs". But, yes, engage those first. And you can drive around with them "on" while in 2WD. (adds drag to your front components, but won't hurt anything if you are properly lubed).
Your proceedure is correct for shifting. If you are parked and have to go backwards or are stuck, they should still engage, but may not immediately.
When shifting into 4lo, you should be stopped - not rolling at all.
You don't have to stop in neutral - the shifter passes thru it, much like a manual transmission does when shifting from gear to gear.

None of the Jeep vehicles are made to "shift on the fly". Doesn't matter if it's a CJ, YJ, TJ. All of them should be at a dead stop to engage the 4WD. Pull the stick back into 4H with the trans in neutral.

You can take it out of 4WD on a slow roll, (under 5MPH), because you are releasing the torque off of the t-case, but if you get it to go in without grinding while moving, you just got lucky...that's all. Everything was lined up to go in without an issue.

Manual says for 4Lo you should be at a slow 2-3 mph roll. And the Dana 300 was advertised as having "Shift on the Fly" capabilities where you could go into 4Hi at any speed. Not that I am going to try it, but that's what it says.

Any idea if there would be any difference if you drove your Jeep in 4Hi, but without the front locked? Wouldn't it just drive like normal?

regardless of what the manual says or what is possible,I believe you will put less wear on everything and get better gas mileage if during normal street driving you have it in 2 hi with the manual hubs unlocked..you will also be less apt to damage anything if you are stopped or very near stopped when shifting the transfer case

Would drive close to normal.. maybe some small power loss, due to the case sending some power to the front axle... and yes just about all jeeps t-cases can handle shifting to 4High on the fly.

not if your hubs are unlocked but as I said earlier,you will get better mileage and create less wear if you put it in 2 hi...Also,you should be able to shift in the high ranges whether it be from 2 to 4 or from 4 to 2,on the fly.However with most any geared piece of machinery,when you are engaging gears,the less pressure that is being applied then the less chance there is in damaging anything.That is why I prefer to shift either stopped or moving slow

Any way to tell if I am in 4Hi vs 2Hi, other than by the shifter. I doubt myself sometimes as shifting into 4Hi sometimes requires a tug and I have definitely not gotten it into 4Hi before when I thought it was, and had it in 4Hi when I thought I put it in 2Hi.

agree, you should be able to shift while on fly. Costing, off throttle and shift. Clutch in or neutral may help. Skinny pedal spinning on slippery surface should help feel if in 4hi. Or steering feel on dry pavement may be indicator if in 4 wd. You got it - shifting to 4lo while vehicle rolling very slightly works most times.
Good luck with the snow. Got 24 inches in 36 hours here.
