Depends on what surface you are driving on and how long you want your Jeep to last. On dry pavement you shouldn't do it all but especially not over 10mph, on loose dirt or snow you might be able to get away with doing it up to 30 mph. If you like your jeep and would like to avoid risking breaking anything it would be wise to stop first then shift into 4wd.
Yes, but if you need four wheel drive you shouldn't be going too fast anyways
Depending on the speed you are going, yes it could really kill your transmission and your engine! But don't be afraid, your car is not suppose to allow your transmission to downshit if your going to fast for that gear.
They are designed to run highway speed in four wheel drive on wet and slippery roads . Using four wheel drive on dry pavement is hard on the drive line .
If it's rear wheel drive it could be a U-Joint going bad. If it's front wheel drive it could be a CV joint going bad. That's just a guess since I can't hear the car.
It doesn't matter that depends if its frontwheel drive of rearwheel drive if the car is 4 wheel drive its not going to get very fast. Rearwheel drives best for speed.
Depending on speed. If not going to fast nothing then.
