I just bought a 2002 H1 with 40k. The milage is correct having gone to GM dealer service records. Predator Hummer Parts list the engine good for 100k. They state this in the section where they are selling the Cummins replacement engine so take it for what its worth. My truck looks to have been taken care of and does not look to be beaten. I change fluids on all my vehicles religiously. I am just trying to figure what I may be in for. Are the motor and trans known to be solid. What are the week points I should look for. There seems to be plenty of replacement parts out there but is it getting hard to this stuff. I have a shop and can do all my own wrenching when needed. Any info would be great.

Thanks, James
