Is their a max speed recommended? Or just when shifting?

Depends: for starters, are you in a Rubicon....or a Mojave? There is a difference.

Why would it matter? Not trying to be a wise guy....just trying to understand.

isn’t the ya safer case the same in all of them?

 

[WaterDR]

Sorry...meant...isn’t it the same transfer case in all models?

Overland

If that’s what you’re driving in now, I’d take it out on a smooth gravel road or across a cut soybean field, stick in in 4H and see what she runs at going up the road (or across the field), at engine redline minus a thousand RPM or so...or whatever your taste for engine operating might be.

no. The low range is lower in the Rubicon.

Gearing combinations are NOT the same...what those combinations are right off hand, I don’t know, but the Mojave runs much faster than the other trims levels...it’s simply not designed/built for the low speed ops.

Shift from 2H to 4H at any speed you want....except 90!

Seriously, if you are in conditions to need 4wd, you shouldn't be traveling any faster than 55-60mph. Just my safety minded opinion.

4lo is a completely different situation.

From P 216 in the manual: ' Do not go faster than road conditions permit. ' Sounds kinda open to me....

The transfer cases are the same though.

Said without saying... RTFM...

Hey guys....I fear I created some confusion with my question. I am not asking about top speed but rather is there a speed that you shouldn’t drive faster than in 4

i have a friend insisting that you should not exceed 45 in 4H.

From digging into this I have come to the conclusion that it doesn’t matter. Go as fast as you think conditions allow. There is no mechanical limit per se.

The Mojave has 4.10 final gearing and a 2.72 low range, the Overland has 3.73 final gearing - BIG difference!

The transfer cases are the same though.

Correct, I've had Ford manuals stating don't shift to 4 Hi faster than 55, but that's quite different to how fast you can go in 4 Hi.
