figured i`d change the diff fluid in the front today, seeing as i neve did it after that trip, and man was it nasty, looked like chocolate pudding, anyways the fluid wasn`t fully draining so i stuck my hand in there to pull it out and i got a nice little shaving, maybe like 1/8th in, then another one, then i went back to back to push the fluid up and BINGO!!!...nice chunk of metal, looked to be a little smaller than a dime, and looks like it might`ve came from the 4 little gears(spiders?)....so....what now???....i got a front axle out in the yard, can i just swap in the spiders?????what kinda project will that be?
