Bummer jeeps. However, it may not ba all that bad. My grandmother drove her car right into the Gulf Of Mexico and completely submerged it. She got it towed and after a through disassembly and relubrication the car ran for quite sometime after that.
I keep a "OH S$%^ kit in my Truck just in case my 4wd doesn't cut it. So far I haven't had to use it, knock on wood. I'm glad to hear that you have one.
peace
Jerry
