4 wheel drive newb

Hey all. So this will be my first winter with my yj and I have never had a vehicle with 4x4. Could someone help explain to me the best way to use it so I do not hurt my jeep? I was driving it earlier and wanted to make sure it worked, but there isnt much snow on the roads, more so just wet, and it was really "clunky" when I was driving. When should I be using 4H and 4L? A crash course would be real helpful from anyone with experience. Sorry if it is a total newb question but I do not want to damage anything.

You can shift into 4H on the move up to 55 mph. Unless your crawling rocks on the trail 4H.

For 4L you need to be at a complete stop and use the clutch.

You should only use the four wheel on slippery conditions and off road. Even when it's wet some will use it but you will get the jerky jerky in a turn.

I always stop and shift into 4x4. You never know if you can trust "shift on the fly" unless you have a transfer case that's electric shift IMHO. And you should only need 4Lo when climbing rocks or a steep hill. When driving in snow, I always use 4lo as a last resort since if your stuck and 4Lo doesn't help you get out, you'll need a pull from someone else. And you will get a bunch if different opinions you'll just need to take what works for you or you feel safe with.

I heard having a tire on the back it's okay to drive in 2WD with snowy conditions.


As long as you have a good tread and don't drive like a asshole, you'll be okay in 2WD or 4WD.

OP if it was real clunky as you described you probably shouldn't be using 4WD and been in 2H. Part time 4WD needs to be used on slippery surfaces, even running on wet surfaces where the tires have traction and aren't slipping is not good.

Thanks guys. So just bombin around town and staying under 50 mph what should I be in when conditions are snowy etc ? 4L is only necessary for hills or getting out if I am stuck but should I get up to speed before shifting it into 4H? I have heard mixed opinions about shifting on the fly. I was probably drivin less than 30mph earlier and in 4H and it was makin some awful clunk noises so I put it in 2WD and it was fine.

You need to be at a stop and in transmission neutral for shifting in or out of 4L. Its not like a transmission where you shift gears to go faster. So if you need 4hi, just put it in 4hi. You can probably only go 30mph in 4 low. Personally, if its slick enough to drive slower on icy roads, I run 4 hi.If your back tires start spinning in 2 wheel drive you can go roundy round real quick in these things.

You might want to figure out what is clunking when your in 4wd before you run it too much. Its probably something simple but it could get a lot more expensive real quick if it actually breaks...

My guess is that it was just a wet road. The tires were still getting traction so they were getting enough bite and causing the clunk. 4wd isn't meant for pavement. I would suggest finding a little sand, dirt or deeper snow and then try it. It shouldn't buck and jerk as much. If it does, you may have a transfer case issue. Welcome to the forum. Good to ask questions rather than break stuff.

It was probably binding/clunking because you had better traction than you thought. It would bind/clunk if you were trying to turn and the tires had good traction. Going perfectly straight it shouldn't bind/clunk, however even going straight you shouldn't be in 4WD if you have very good traction.

Shift into and out of 4H on the road as conditions change. It is a part time 4WD system that needs driver input. It is not AWD or Full time 4WD, and this is why some people experience problems. You'll get used to it as time goes by, and you understand how the system works.

Thanks so much guys. I took it out today and 4L works fine but 4H doesnt seem to be engaging and it is spinning. I am not too sure as I didnt want to break anything. I was at a stop and put it into 4H and it made noises I wasnt liking so I gave up on it. Should I be at a stop then put it in 4H then get moving? Im thinkin The 4H is not working so maybe just leave it be.

I always stop, put it neutral, engage 4wd ( hi or low), back up then take off wherever Im headed. Same for disengaging. Stop, neutral, disengage, back up then head off wherever.. Thats just my preference, its not actually necessary in these with 4 hi and 2hi. 4low you do need to stop...

It sounds like your linkage might be out of whack if you get 4 low but not 4hi. You should be able to get 4hi to ingage somewhere if you ignore the marks and go by feel. And Your sure your not just passing 4hi and hitting neutral? 4hi is just one click back from 2hi... Then you'll hit neutral and over and down is 4low...

I will definitely check it out next time I get some slick snow or something to drive in. But I was pretty sure I was in 4H, although you never know.

Hey all I have not replied to this thread in a while but it seems my four wheel is not engaging at all. If I put it in 4H and start driving I can hear some clunking noise under me but it will not engage. Does anyone have any ideas that I can test or try myself? Just hoping there is somewhere to start before I go pay someone a bunch of money for something I may be able to figure out myself. Thanks for any help in advance everyone.
