ARRRGGGG That picture brings back lots of memories, bad ones. I wish I had a dime for every time I had to crawl under and work on a HMMWV that looked like that.
I hope you were a better driver then the ones I had to deal with. When they washed their hummer they would miss a big spot of mud on the inside of the wheel, above the greaded hub, so when the drove it it would vibrate like it was coming apart. Then the come crying to me and I would tell them go wash it again, they would in turn go cry to they TC (1sgt, XO, Capt, or higher) and when there TC shows up I would have to crawl under the truck with a screw driver and pry out a piece of mud the size of dinner plate and make the driver look like an fool.
sorry for the rant.
