I have a 2004 GMC Sierra extended cab, short bed. I would like to find
the axle ratio and engine size. I am pretty sure the engine is a 5.3
Vortec, but I'm having trouble finding the axle ratio. None of the codes
in the glove box match anything I read on line. Any pointers? I will
need to be towing a trailer quite a bit in the future and need to know
how heavy I can go.
Thanks
