So as mentioned in the title, when I put my transfer case into 4L it seems to hesitate and stutter when put under load.. (Example: put it in 4L and attempt to climb a small hill.)

When I put it into 4H there doesn't feel to be any issues. I drove it in 4H at about 20mph just to test it out.

I'm not 100% what kind of transfer case I have, I was told I have a 231. The jeep is all stock and original. Haven't owned it long. Less than a week.

I was told by a friend of mine that the 4wd is operated by a vaccum system, and he believes that the issue is a vaccum not being fully sealed. He drives an old YJ so I don't know if that's accurate or applicable to a 92 cherokee. I did find a dry rotted vaccum hose coming from the vaccum canister and I replaced it.

Any insight would be appreciated.

Shift like this:

Here's how the factory suggests you shift the transfer case and I've been doing this since these things were new and I worked at the dealership. Quoted from the owner's manual. The suggestions in CAPS are mine.

"To engage, shift the transfer case lever from 2H to 4H while the vehicle is moving at any legal speed". I LET OFF THE GAS, THROW THE LEVER, TAP THE GAS AND LET OFF.

4L position: " To engage, slow the vehicle to 2-3 MPH , shift the transmission to Neutral, then shift the transfer lever to the right and pull firmly rearward to 4L".

TO SHIFT OUT OF 4L, SHIFT THE TRANSMISSION INTO NEUTRAL WITH THE VEHICLE STOPPED, SHIFT THE TRANSFER CASE LEVER TO 2H, THEN THE TRANS TO D IF YOU HAVE AN AUTOMATIC, OR INTO FIRST GEAR WITH A MANUAL, AND CONTINUE ON.

Thanks for the reply, I appreciate that, but unfortunately that doesn't help my situation. What I'm saying is that when I'm in 4L and attempt to climb a small hill or put the jeep in a situation where it really needs to have some power put into the transfer case (like a load) the jeep shutters almost like it's slipping.

How are your motor and trans mounts?

You're more than doubling the torque on your drivetrain in 4L.

And, that torque twists stuff like transfer case linkage......
