4wd Clunk: N or 4lo to 4hi

Just got a new to me JKUR! When shifting 4wd from N or 4lo back to 4hi I've noticed a very loud clunk/bang noise. The transmission is in neutral, car is drifting forward <1mph. Is this normal?

Here is a video:

If it isn’t normal then I’m in trouble also because mine does it as well. It is normal based on what I’m hearing. If in doubt, go to a dealership and try theirs.

Pretty much. In and out of 4Lo will clunk. Good on you to have read the manual or this forum to be slightly moving! Many will not do that. Read or be rolling .

Be careful not to force anything, there is just a plastic clip on the control cable. And it breaks easy. But you probably read that also.

You don't really need to be rolling forward. You just need to be able to move the tranny gears till things sync up enough to make the shift. This can be done rolling, or standing still.

Thanks everyone! I read about those plastic clips on the forum. I bought 2 to keep in my tool kit

And the rolling thing I definitely had to practice. The first few times I did it, I was rolling too fast and it sound like a blender...rest in pieces gears. Hopefully I didn't damage anything...

Now I've got it where I can go into 4lo on the fly no looking no real grinding. Figure it's better to learn now than when I'm about to get into something rough on the trail.

This forum and commmunity has been a huge help. I've had a jeeper stop and help me work on something on my Jeep. Had an apartment neighbor jeeper help me move furniture without asking. Trying to pass it along to others.

The awkward transfer case shifting isn't just a Jeep thing. I have an older 1998 F-150 4X4. The TC lever has the exact same shift pattern as the Wrangler. And.. It's every bit as clunky going in to Neutral/4Lo.

Great video! I went wheeling for the second time a few weeks ago and had an issue getting it into 4L so I could turn the lockers on. I knew the linkage was held by plastic so didn't tug, just kept rolling in N very slowly till it went in.

Do they not make those plastic clips in metal via aftermarket? If not, whats a good place to buy the plastic clips as I too would like to have a spare just in case.

I bought some on Amazon for about 8 dollars. From what I read, you may not want to strengthen that plastic. Some people were saying it was designed to break to protect the t-case from damage. I can't confirm this to be true, but would make sense.
