On the fly shifting into 4x4?

[BioStroker]

I just scoured my owner's manual for information regarding speeds for shifting into 4x4 from 2wd, but couldn't find anything. What is the highest speed you can shift into 4wd without damaging anything?

Shifting into 4wd at speed I have always used the rule of thumb of up to 55MPH. I read that somewhere a long time ago.

I also look at it this way, anything above that you are not wanting to have to turn at that speed in 4wd.

Now, once in 4wd, I have ran my truck at over 100. BUT, that was in a straight line down a 1/4 mi track.

i always just stop. or at a roll. i dont like to chance it. but you can take it out of 4wd while moving.

i believe 55mph is right but i dont think i would do runinng that fast

i say if you're at a speed to need 4x4, you're prob at a safe enough speed to engage it. i always just make sure to let off the gas during the shift

I always shift at a roll.... just seems right.

Do you think the same for 4 low also DKR? I've always actually stopped, put in neutral, then engaged in to low then back into drive after I hear the thud. Come to think of it never actually used 4 low with this rig. But yeah 4 hi about 40 I've always felt ok.
