Think of an arc (( in a turn the back tires don't travel as far as your front tires. The 4x4 system does not allow the front and rear axle to turn at different speeds on your Suburban. So the tires have to slip, hence the chattering.

On many other AWD system, like some Jeeps, there is a cluth in the transfer case that allows either axle to turn faster or slow than the other.
