[Hummerguy32]

Hello Everyone Thank You in advance for all replies given!!

I would like to save on money on the changing the rear and front differntials fluids on my 2003 Hummer H2 80,000 miles young. Can anyone point in the right direction on how to start this project which hopefully includes what type of fluid and how much I need, what is involved with changing out the fluids (does it consist of a full flush of the fluid?). Any other concerns please note them for me. Thank you again!
