I Went to sell my long loved jeep today and seemed to have it in the bag, that is until i went to throw it in 4 wheel. The jeep clunks when i try to engage in 4 wheel or 4 low. The noise seems to come from the transfer case. Just looking for a ballpark idea of what i might be up against. Its an 86 CJ7 with a 5 speed T-140
This is somewhat true. The trick is to get it in smoothly. Some do best at a stand still in neutral with a stick or park with a automatic and brakes helpd and some do better when it is rolling at a few MPH and in neutral. (BTW, even in neutral a automatic provdes some drive to output shaft hence reason park if standing still with automatic)
Clunks might be normal if you're getting it engaged into 4WD and 2WD all right.
I just replaced a tranny & a transfer case because I didn't pay attention to the clunk my 84 was making (I kept driving it in other words). If it's NOT engaging in 4WD, try rocking it back & forth, or even fred flintstone it forward a little.
My clunk turned into a wicked vibration up through the transfer stick
- I kept driving rather than get stranded in the boonies. After reaching a service station, I shifted it into 4WD trying to make sure it hadn't bound. When I tried to move it wouldn't...tried to free it from 4WD and it had bound.
I know with my 99 wrangler TJ it does not clunk. When I put it in 4 wheel drive low or high. But My baby is also 10+ years newer to. Also did it always clunk when you put it in 4 wheel drive? If not you may have a problem. Good luck

Here are a few pictures of my rig I will update soon as I get new batteries for my cam
These things always clunk going into or out of 4wd-Lo, just some big gears that slide together. Best to have the clutch in, vehicle just rolling as slow as possible.
4wd-hi should engage at any reasonable speed without clunking. If it does, first thing to check is proper level of good clean fluid. It's common to have them low or contaminated with water.
If the clunking is (somewhat) continuous and not just when you try to engage it, first thing to look at is the adjustment on the shifter. Take the rods off the shifter, insert a pin in the alignment hole, make sure the shift rods match up with the selector arms.
If all those don't work, time to tear it down and inspect the innards. :(
Yes you are wrong.... I have been driving 4x4's for well over 35 years and currently own 3 of them now. Do not even try to tell me that you know more about what is right and wrong here. I can basically figure out how to shift any of them smoothly once I feel them out because when you have shifted them as many times and for as many years as I have you know. BTW, I would not even own a 4x4 with push button if you gave it too me. (they are likely you speed too) I have run many plow trucks for many years and I can shift in and out of 4x4 or low range 20 to 30 times a day and more and in all my years of doing it I have never lost or damaged a Tcase, tranny, drive axles or engine. Also sometimes even a fresh lube change can help a stiff Tcase.
Well, you got me beat, only 2 4x4's in my stable right now, although I got my first one(a Toyota Land Cruiser)for my high school graduation in 1969. I'm not a fan of push buttons, either. In fact, even the vac. axle disconnnect system in my Jeep has been shitcanned for the manual cable style.
Your shifting advice was OK, I had no complaint with that, although I find that both my vehicles shift easier if you're rolling just a bit when you pull the lever.
My comment was about your claim that the transmission still drives in neutral. I ain't gonna get into a pissing contest here, but because this *is* the internet, and you don't know me I'll just say that for the last 30 years, while you've been pushing snow around people's parking lots, I"ve been feeding my kids by working on cars. My guess is that I know at least as much as you about transmissions, and I say you're full of shit. There is no drive in neutral(thus the name "neutral"). Any rotation of the moving parts is because of friction between these parts, and is very easily overcome. In fact, the only 4x4 I've ever had with an auto trans('74 International 1/2t p/u)would not hardly shift into 4Lo if it was in park...had to be in neutral...just like the owner's manual said.
