i was trying to explain it in simple terms is all
it's a bit complicated to explain without diagrams and arrows and stuff
it will of course burn out after a time, but it's the length of time that is the issue here, worn tyres front and rear won't make a difference in the great scheme of things but a small difference in profiles will eventually lead to it being kaput, but the nature of the diff is that it will still "work" just not as well
the noly downside is that the "spin" in trying to drive the front wheels is less power going tot he rears, so on slippery surfaces it's going to be a very effective traction control device if he wants to find a frozen lake to test it on
