Switch on the dash electronic 4x4 - Yes its shift on the fly.
Manual lever on the floor - No, you need to be less than 3 mph to shift into 4x4, or 4x4 low (preferred method is to come to a stop).

It is shift on the fly with either manual or electric shift transfercase. You can shift in and out of 4x4 high as long as you aren't spinning the tires. 4x4 low in either case, you need to be stopped in neutral with your foot on the brake.

Yup - I know folks that have switched to 4wd-high at 55 mph.

It's true that it is....but I don't have the guts to try it! I've had 4 WD's for over 30 years and have bad memories of horror stories of doing so "back in the day..."

alittle off topic but since we are talking about 4x4 i figured i would ask. My dad got stuck in the field yesterday and i went and pulled him out... Well it seemed that only my left front wheel was pulling my right front isent even dirty! Do you have to lock in the hubs or what?

Sounds like you have an open diff on the front axle. Locking the hubs won't help. This is why hardcore off road guys install air lockers on their front axles. Then you can lock the diff when one tire is wanting to spin but you can unlock it again when you want to do something really wild, like drive on the highway.

Per the owners manual:
Shifting from 2H (2WD High) to 4H (4WD High)
Engage the locking hubs by rotating
the hub lock control from FREE to
LOCK, then move the transfer case
lever from 2H (2WD High) to 4H
(4WD High) at a vehicle speed
below 3 mph (5 km/h).

With the manual transfer case, you need to come to a stop (or speed below 3 mph) to shift into and out of four wheel drive. You don't need to put the transmission in Neutral like you do when you're shifting in and out of 4-wheel low.
