Silly question about shifting the 4L mode

Ok, I know I am a noob. But according to instruction I should shift it when moving like 2 to 3mph. Today I finally got a chance to do some light wheeling on dirt and mud path. Then we bumped into really angled path. I wanted to shift to 4H and disconnect the front axle.

But I was pulling the shift and it wouldn't budge beyond 4H. I could done it harder but I didn't want to mess it up and end up stranded there. I know I am new at this but next time that could be handy. I managed to get out of that place but had to do lot of wiggling .

To put it I. 4H you pull straight back. In order to put it in 4 low you push right towards passenger door then pull all the way back. There is a stopper behind 4H so you don't overshoot unless you really want it

You have to put the transmission in neutral to put it in 4-Lo.

What do you mean by disconnect the front Axel? Do you mean you have front lockers (locking differential) that you wanted to unlock? Or do you mean you wanted to shift out of 4 wheel drive (into 2hi)?

You should be able to shift between 2 wheel drive (2hi the frontmost position on the lever) and 4hi (the next position down) without problem while driving (up to 70mph, i think) or at standstill. the lever should be stiff-ish, but if it doesn't shift between 2hi and 4hi while driving, you may have a problem

To get into 4lo, you have to lower the lever further. First you hot a neutral position, then if your lucky out can slide down another position into 4lo. You should always be at standstill or coasting no more than a few mph when shifting into (or out of) 4lo. You also need to be in neutral.

If you are trying to switch in or out of 4lo, it can be rather finicky. In particular if the gears are not well lined up, it may be that it won't go into 4lo and stays stuck at neutral. sometimes it'll slide into neutral but won't go back into whatever mode it was in or into the new mode. I'd that happens, just wiggle it around. If you are on a slope, let the Jeep roll a few inches to move the gear inside. Don't panic, it's just the gears aren't well aligned. You can also shift (the regular gears) out of neutral and gas the motor a bit but shift back to neutral before attempting to shift the t-case again.

Don't forget to clutch in or put an auto into neutral before shifting to 4 low.

My jeep was very tight to put into 4low the first about 5 times.

Copy paste from the 2012 user manual

Shifting Procedure
2H to 4H or 4H to 2H

Shifting between 2H and 4H can be made with the vehicle stopped or in motion. With the vehicle in motion, the transfer case will engage/disengage faster if you momentarily release the accelerator pedal after complet- ing the shift. Apply a constant force when shifting the transfer case lever.

4H to 4L or 4L to 4H
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift an automatic transmission into NEUTRAL (N), or press the clutch pedal on a manual transmission. While the vehicle is coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer case lever firmly to the desired position. Do not pause with the transfer case in N (Neutral). Once the shift is completed, place the automatic transmission into DRIVE or release the clutch pedal on a manual transmis- sion.

NOTE: Shifting into or out of 4L is possible with the vehicle completely stopped; however, difficulty may oc- cur due to the mating teeth not being properly aligned. Several attempts may be required for clutch teeth align- ment and shift completion to occur. The preferred method is with the vehicle rolling at 2 to 3 mph (3 to 5 km/h). Avoid attempting to engage or disengage 4L with the vehicle moving faster than 2 to 3 mph (3 to 5 km/h).

Pretty sure he's talking about disconnecting the front sway-bar. Most jeeps require crawling under the jeep. With rubicons you can disconnect the sway bar with a button as long as your in 4wd (high or low). They will reconnect if your going over 18ish mph for safety. You disconnect the sway bars because it smooths out the ride and gives better traction in rough terrain. The rubicons lockers (not modified) only work in 4low.

It's easier on your jeep to be in 4low if you at all need it. Even more so if you have a manual to be nice to your clutch. I find the rolling engagement is a pain, and always seems to grind. I stick it in 4low when stopped. If it doesn't slip in then just move forward a foot an try again. You don't want to pull much harder than you would pull you finger because there is a bushing that can pop off if your too rough. This link talks about it. http://www.wranglerforum.com/f33/not...eel-99139.html

Good thread. Like it says above, if all else fails, read the manual.

oh wow, didn't occur to me to shift to manual and try shifting to 4Lo. Thanks guys. Sorry I meant the sway bar. next time I know what I should do to switch to 4Lo. had a funny path that was mud with rocks that day but glad I got out of there before it got too dark. (Sun was already go so it was dark).

And next time don't go alone if you don't know the trail and get a winch. Lesson learned.

...shifting the transfer lever is a bit like making love.... proper timing and careful tenderness will provide better results....

....and I'd swear, there's an identifiable "J-spot" on each Jeep linkage just a ~little~ different from every other Jeep...yet they all seem to respond to the right touch....

@Jeeper,

Couldn't have said it better! Now that my jeep is several years old and I've had a chance for a lot of practice, I find that if I'm stopped and can't get it into gear just moving the jeep a slight amount while holding it against where the lever has to go (hi or low) she falls right into gear without too much tugging. When I first got the jeep I was nervous as hell while doing it and probably was using guerrilla strength without realizing it. That is what happens when adrenalin is flowing. So, when all hyped up, breath a few times, think about what you are doing, and then slowly move things around.....and apply JeeperJake technique!

Anyone know if the new jeeps still have the plastic bushing in the linkage?

Yes sir they do! They have to have a weak point somewhere so that the weakest point isn't the shifter and the transfer case. If not, you could put as much force on it as you want and kill your transfer case if you didn't do it right
