4x4 grind question

So on my drive home tonight in a huge snow storm, I engaged 4x4 foot OFF the gas like the manual and my daddy taught me. But I did it at around 50-55 mph, I heard a slight grind and then she went right into 4x4 and in the driveway I tested it up a hill and 4x4 works fine. Could this be a problem in the future? Basically did I grind the shit out of the spline or is it a normal thing and it'll be ok?

It'll be fine. However, although the manual says you CAN be doing 50 mph when you engage 4H, the question is SHOULD you? If conditions allow you to drive that fast you probably don't need it.

good point, but its a car manual. odds are you could do it at 100 and it would be fine. but, like you said, should you?

if you are already going 50 in a snow storm, you are probably going in a straight enough line that 4x4 wouldnt help at all.

I get a slight grind occasionally, it happens. not going to kill your gears.

Thanks guys, it was for passing people doing 15 on a 4 lane highway. Wouldn't say conditions were good enough for 50 on the highway but I wanted to get home

This. Plus, if you're going too fast for conditions the chances of not getting home are drastically increased. Just a thought.

i never drive faster then i can see. Besides that, its all in the reflexes. i had a pregnant wife at home sick without power and no one to turn the generator on, at that point id redline my jeep in 3 feet of snow if i had to. you know youd do the same, dont judge

The gears are turing at the same speed. There is no difference if you are going 20 or 70mph. Now if the tires are not very close to the same size then you will have an issue.
