Guys can someone answer this please...
When shifting from 2WD ( normal) driving to 4HI...i don't have to put in neutral correct...
I just have to be at a slow speed...And when i don't need anymore pop it back up to 2WD...
4LO is something different...

 

Yes u are correct......

 

Yep, you can actually pop into 4hi at speed. Something like 25 mph. Not sure on the exact speed but its in the manual. 4Lo is the whole nuetral thing under 5 mph I think.

 

Thanks guys...

 

Read your owners manual! It's all in there, everything you ever need to know about your Jeep, it's why they make them!!!

 

This page.

 

Manual says 55. I'd have no fear of doing it even faster but the question is in what situation would 55 even make sense?

4 low you need to be like 0-1mph and it likes to not go in but don't force it, simply roll forward or back a tiny bit and it will come right back.

 

On our paved secondary roads in the winter, the surface often will alternate between dry pavement to a layer of ice and/or snow. This is mostly due to the open fields letting snow blow across.

Because of that, I shift back and forth often between 2wd and 4-high. Usually between 50 to 55 mph. I have had this 07 since new, and it has caused no harm at all.

 

Gotcha Yankee...When i had my 08 was doing the same not quite at those speeds...Had no problem...
Will do the same with th 12...It's 4LO you have to be careful...Thanks...
