So I get my new truck the other day, '89 Jimmy, and I'm toolin' along down the freeway to get home. I stop at a gas station and notice the pinion seal on the rear axle is leaking. So I go into the station, buy some gear oil, and fill it up. I figure I'm replacing the axle anyways so it doesn't matter. Then, about 2 miles from home, I hear a funny clunk. I open it up when I get home and not only is it full of gear oil (not sure how that happened since oil was practically spraying from the pinion) there's a small piece (like half of a dime sized) missing from the carrier. So I get out the die grinder and clean it up and as I'm about to close it up, I notice the missing piece. Only problem is it's wedged in between the ring gear and the housing. It's on the top side and I can't get it out for the life of me. I can't move it forward or backward. I've put the truck up on jackstands and ran it in reverse and it won't move. It just keeps scraping the ring gear. My question is, should I pull it apart to get this piece out or am I wasting my time since I'm gonna replace the axles anyways. Mind you I need this axle to work for a week or two, but that's all.
