Shifting into 4 wheel

Mine is a 08 and when I move the lever or try to into the 4 w/d position it’s really a challenge. I’ve soaked the linkage from underneath a number of times with penetrating oil. Not much of a difference. How easy should it be and what should I do or look for?

It should not take excessive force. But it is a matter of finding the right technique. The gears need to line up. If they don't line up, you don't want to force it or the little plastic link may break. It is usually easier while you are slowly rolling, and either in neutral or with the clutch in.

Are you talking about going from 4H to 4L.. Or from 2H to 4H?

As GuzziMoto points out, there's a bit of a trick shifting to 4 Low, It's not uncommon to feel resistance and hear a bit of grinding now and then... But 2H to 4H should be next to effortless.

2H to 4H is SOMETIMES difficult because the gears aren't always meshing at a compete stop. You shouldn't really be stopped anyway when shifting from 2H to 4H. The jeep is specifically built to do that on the fly from low speed all the way up to around 50. Feel free to knock it in and out of 4H (from 2H) at anytime and as often as you like while moving. No need to shift to neutral. The gearing is synced and no damage will occur.


It's shifting into 4L that you need to be careful. The gears are not synced and you need to do that at no more than a couple mph

Yep good to clarify that.
4lo barely rolling. 4hi, no problem at most reasonable speeds.

In that case shift while on the move - though personally I don’t shift into 4x4 over 55 mph.

The thread is getting a little off the rails

In my 2016 there is hardly any effort required to move the transfer case lever from 2H to 4H (Whether in motion or not). It feels no different than shifting the automatic transmission lever from neutral to drive.

If you are feeling a lot of resistance from the transfer case lever when going from 2H to 4H, then there is a problem.

On my 2012 with 127k miles that I think may have never been or very rarely shifted out of 2H it is very firm to move to 4H. It is positive and smooth but takes quite a bit of effort. Not sure if they are different but it is the 6sp manual.

Yes, both the manual trans and automatic trans should be rolling / moving when shifting between 2H and 4H. You don't want to be accelerating, typically you want to be coasting. But you want to be moving. I don't know if the automatic wants you to put the trans into N (instead of D), with the manual we just push in the clutch. To shift into 4L you want to be nearly stopped, but some slow movement can help the gears line up.

It gets easier with usage.

I guess it's wrong to generalize, but -personally- my 2H - 4H shift has been butter smooth from the time I had 6 miles on the clock and all the way to the present.

Whether at a standstill, or moving, shifting the TC between 2H and 4H feels exactly the same. Here's a cut-and-paste from my '16 owner's manual:

You can shift from 4H to 2H and back without moving. I do it all the time in the winter when at red lights and my transmission in gear.

Yeah.... again... SOMETIMES you can't get it while stopped. A gear is out by a hair and needs to be spun a bit. Other times you're on a slight incline and there is too much pressure up against the parking pawl. Don't forced it. Creep forward an inch or 2 and it will go.
