What is the safe top speed to drive the JLU in 4 h the only thing I see is very vague.

Depends on the driver and the conditions.

I think you can shift into 4hi up to 45mph. You can go faster than that once you’ve shifted. The real question is whether or not one should drive faster than 45 in snow that requires 4wd...

That’s what I was guessing from the manual.

I suppose if you are overlanding on dirt or sand you may want to go faster.

Might come down to engine RPM. Someone else smarter than me can do the math given ratios and tire diameter.

Oops nevermind, 4H is still 1:1.

Would it be safe for our tranny to be shifting while racing across the bumpy desert?

There is no max speed for 4wd high.
