I have an 89 Jeep Cherokee in great shape, is there anything that I need to know before putting it in 4WD?

It has an auto tranny, just wondering if I have to lock anything in or back up or anything like that?

Check the owners manual if possible. Not sure about an 89 but my 98 Wrangler goes into 4 HI by pulling up the 4WD lever while driving less than 55 mph. Might be a good idea to find someone local with a Cherokee and asking them. Look for a local Jeep club they will be able to help you.

Be on a slippery/off road surface. You will break parts on dry pavement.
It is an “on the fly” engagement so you can be moving, but consider your speed, just the same. Slower is better.

Had one. As stated above best to engage it on Muddy, snowy or otherwise slippery conditions not dry pavement.
Also you may have to back up a few feet to disengage it. They fixed this later, depends on your build. If it feels like it is tugging your hands side to side as you turn in a parking lot, it might be in 4×4 mode.
Should not have to lock anything, but a visual inspection of your front wheel hubs would show you if an after-market hub-lock was installed. Not from factory.

Depends which 4WD you have. Command trac (NP231) has 2HI – 4HI – N – 4LO options. Select trac (NP242) has 2HI- 4HI Full Time – 4HI Part Time – N – 4LO options.
All the 4HI are shift on the fly, but recommended below 55MPH. 4HI Full Time is where you’ll keep it most of the time in 4WD. It allows differentiation between the front and rear axles for normal driving.
The NP231’s 4HI and the 4HI Part Time are the same. It’s 4WD but the front and rear axle are locked together for maximum traction. This setting should only be used for slippery conditions. if you try this on dry pavement the truck is going to hop and skip when you try to turn a corner.
4LO is generally for off-roading or for low speed power. Come to a stop and put the transmission into neutral. Then shift into 4LO. Be gentle with the gas as you’ll get tossed around if you’re not. Put it into neutral again to shift out of 4LO.
