i think i know the answer to this but i figured i'd ask to be sure. is it bad for the diffs when the tires shake because they are unbalanced? driving around in winter a lot of times there is buildup of ice and snow in the tire so at certain speeds it'll shake pretty bad. i don't think it's a problem other than the discomfort because the wheels are still travelling at the same speed but i just wanted to make sure

 

I too have wondered about this.

 

prolonged vibrations, will destory anything.. off balance tires wont do much but rattle things... so why worry about, just clean out the snow like the rest of us..

 

snow is easy to clean out, ice isn't

 

An inbalance will cause anything to shake apart eventually. The Diffs are a long way down the line from the tires though. The vibration caused by out of balance of wheels would be mostly absorbed by the suspension and outermost driveline.
