How the heck do you get in low gear?
There should never be a time when you cannot get your jeep into 4L...even if you are not moving. Sometimes it will slip right in when stopped...depends on the position of the gears. If you are not rolling and are unsuccessful in your first attempt at shifting into 4L, move the vehicle a few inches forward or back and try it again. A matter of inches is all it usually takes. Sometimes, turning the vehicle off and restarting is all it takes. As the manual states, shift from 4H to 4L in one smooth move and with a firm (but not too forceful) pressure. Some people prefer to shift into 4L while stopped because they do not grind the gears. If they do not succeed on the first try, they just jockey the vehicle back and forth a few inches, put it back in neutral and try again. I don't know why every manufacturer but Jeep seems to have figured out how to design a vehicle that shifts smoothly from 4H to 4L. Grinding gears cannot be good...even if Jeep says that it is normal. They must count on the fact that most jeepers don't use 4L often enough to cause significant damage.

^ This.

I really had to muscle mine into 4L.

Thanks for the advise Moab. Just another questioin regarding 4wd...

In the manual and a you tube vid i watched Jeep says that its not good to run the 4wd unless the road warrants it.. In our winters up here we can have dry roads and suddenly get into slippery slush stuff ... Why does Jeep say you shouldn't drive in 4wd unless on slippery roads.. Why can't I just leave my wheels in 4wd and not have to worry about burning up the tranny? This was not an issue with my CRV..

If you are simply driving in a straight line, it doesn't cause as much of a problem as turning, going around curves, etc. If the wheels are unable to slip (or hop, as some would say), a lot of stress builds up in driveline components since they are bound together in 4WD but your wheels turn at different rates going around curves. I don't think the problem would be with "burning up the tranny". It's more in axles, ujoints, driveshafts, etc. If you've ever heard someone with full-time lockers try to turn a corner on a city street, you get an idea of the problem. One tire screeches intermittently as it completes the turn...releasing the stress that builds up in such a system very fast. I had a friend break an axle once with full-time lockers simply because one wheel was unable to slip on a not-so-slick slickrock trail.

If you are driving on mostly slushy roads and need 4WD, then leave it in 4WD. When you get to the point where the pavement is mostly dry, slip it back into 2WD. I'm not a mechanic, but it seems that periodically shifting into 2WD would release any of that built up stress on driveline components. This is not just a jeep thing...it's the same with any part-time 4WD vehicle I've ever owned.

I've had my '13 Rubicon for about 3 months and probably have gone into 4 Lo at least 15 times. That being said, at first I too thought it was a bit rough, but I got used to it after just a couple times and now don't have any issue. Honestly, I think I got better at doing it "firmly", only took a few times. I am in Neutral rolling maybe 2-3 mph btw. It's kinda like getting used to exactly how much brake or throttle pressure you need in certain situations...it's a feel thing. Now I can hear it go into Lo (not a grind, more like a thunk) and "feel" it thru the shifter as well. If you can, maybe go to a dealer & test drive another one for comparison.
