I have two questions regarding the new 2009 Tahoes.
First, is the G80 (heavy duty locking rear) available with the new GUA 3.08 ratio XFE rear axle? Is the G80 just the Eaton locking device installed in the GUA rear axle, or is it entirely a different type (heavier duty) differential/housing?
Secondly, will the new aluminum block 5.3L (LY5 XFE Flexfuel) engine last as long/be as dependable as the iron block 5.3L engine and what are the disadvantages of the aluminum block?
