Don't mix tire sizes on AWD's

D1 drivers and any Full time AWD drivers, don't mix tire sizes front to rear. This is the remains of a centre diff from a D1 with 31s on the front & 33s on the rear. I suspect it was driven for a while after the initial noise was heard, and driven until it would not drive at all.

The problem is the design of an LT230 causes oil starvation to the center diff at speed. Any appreciable differential action while drive fast smokes them quickly.
