Question 4wd Issues

So I was out wheeling with some guys and everything seemed fine. Going up the trail had it in 4hi and was fine. Get to a point where there are some mud holes and had some issues. One of the guys got stuck so I went to pull him out, still in 4Hi so we hook up and I start pulling. He is good and stuck and not moving a bit and im just reving and also not moving. At one point it pops out of 4wd and I start spinning. Trying to get it back in 4hi for a little while with no luck. Finally got the lever up but the light wouldnt come on. This was the first instance ive really had a 4wd issue and also the first time I tried to use the 4low. I go to put in in 4 low and the lever gives some resistance but finally goes and the light comes on but I hear a loud grinding noice. Not even moving just sitting still in 4low and it grinds something wicked. I didnt want to mess anything up so put it back to 4hi and had no issues. Today I got underneath and cleaned things up and tried to engage the 4wd right in my driveway but it does the same thing. I dont know where to start. I thought id give it a shot and see if any of you guys and gals had any similar issues that could provide so good advice. A little more about my jeep incase it helps, its a 2003 4.0 I6 automatic. Not sure what could be causing this, please help.

Sounds like you might have multiple issues. After you check your fluids, check your linkage. Mine was out of adjustment from the factory, and the first time I applied any real power in 4H it would pop out. Took me a couple shots to get it adjusted right, but now it works flawlessly.

Did you adjust the linkage or have someone else do it for you?

Alright, I had a similar issue, I went wheelin on my own just for fun one afternoon, and went through a puddle in 4L and had to do a 3-point turn around afterwards to get out, and after I backed up, I put it back in drive and hit the gas and then 4L fell out. Could that be the linkage or something different? 4H works perfect, haven't tried to put it in 4L since

So I just got done changing the fluids and cleaning up my mess. Got in fired it up. Put it in 4hi, no problem. Crossed my fingers and put it in 4low and wow, it went no grinding or any problems at all. Back to 4hi then 2wd. Drove around the block and thought I aughta try it again, and of course it doesnt work this time. 4hi has no problems that I can tell but 4low will grind or pop out every time. I really dont wanna screw anything up so when I hear it grinding I just stop. If I hold the 4wd lever all the way back and go from neutral to drive it will work for a sec then pop out. I am lost....

Once I got to work, sitting in the parking lot, just tried to pull the lever to 4low and it grinds.

The Jeep needs to be in 4 Hi moving 1-2 mph, push in the clutch or put it into neutral and wile still moving 1-2 mph pull the lever into 4 Lo. You need to be moving SLOWLY to get the gears in the transfer case to mesh properly. Trying to pull it into 4 lo at a dead stop will just cause the grinding you are describing. If you try that a couple of times and still get into 4 lo, or if it goes in but popps out, you probably need to adjust the transfer case linkage. A linkage adjustment after a lift has been installed is not unusual.

So I did just that and worked like a charm. Just a pain in the ass to not be able to just pull the lever whenever you want 4low. I guess Its not a huge deal, as long as it works I'm happy.

Some folks don't have to do that... but some Jeeps are picky and require a little bit of a roll. Mine engages 4lo with no issues whatsoever at a dead stop with my foot on the brakes. I'd also check your linkage to ensure it's not just hanging up a little... to check linkage, put tcase in 4lo (engine not running), loosen linkage bolt and ensure the lever on the tcase itself is fully in 4lo, then tighten linkage down from that position. Put back and 2wd, start engine, get on some loose gravel or somewhere you can safely use 4wd and test it out.

Thanks for the tip. I def would prefer being able to just pull the lever, can't rely on always finding a slight hill to be able to roll so the 4low engages.
