Is actually some post off fluid leaking, and burning off... I know what is leaking i just don't know WHAT it is. But randomly, and luckily a tow truck driver stops within minutes of us pulling over. Says its the rear diff, gets my bcaa number, and tows us to st catharines toyota dealer. Well, we're in ontario and its sunday so naturally nothings open. Also, dealers have the stupidest parking lots ever. At first we tried to push sally in to a spot but ended up rehooking her up and doing it that way. While she was jacked up, we took a good look, turns out when the changed the rear diff fluid, they didn't tighten it so from nashville to today its been leaking until no more lube, metal on metal, snap. Yay. So the driver took us back to our hq, we grabbed lisa's car and a couple granola bars (have i mentioned we haven't had breakfast?!?) we're just arriving in london, we all have pee, we're hungry, and we're nearly two hours late. It's going to be an awesome week... Can only in up from here.
