Last night I went and looked at a HMMWV that is for sale. I'd never driven one before, so I don't know what's normal and what's not. The last time I drove anything painted flat green it was an M151 or an M880.
Overall the truck was in pretty good shape. It's an ex KS NG M998, manufactured in 1992 and has about 35K miles on the clock. It looks pretty good and started right up, idled and ran fine. I took it out for a short drive on the gravel road. It seemed to drive OK, but I was unable to get it over 40 MPH. On the way back to the guy's house I had it floored, and the speedo still never got above 40.
Is this normal, or a common sign of a specific problem? Transfer case stuck, air intake blocked, etc... I've already decided that this particular vehicle is not for me -- it has an off-road-only title and I'm not in the mood to try to fix that. Just want to know if it's something easily explained.
I did try cycling the transfer case from HL to H to L. When it was stopped and idling it seemed to shift fine, any other condition it wouldn't. I'm not a 4WD kind of guy, couldn't remember what I had read about a function check, and by then I'd found out about the title so I didn't do any in depth investigation.
