I had a noise coming from the rear of the car. Thought it might be the ujoint. Parked it. Its been a week since I've been able to crawl under it because of rain. I crawled under it tonight when I got home from work. Turns out the plug in the rear end (non threaded) has blown out. What would cause this and can I get a new plug for it? I really need help on this one guys. I'm in a real bind with no car and having to pick the kids up. It sucks having to depend on someone to pick me up and get the kids. Please help me.
