Hi, I have a 1995 Ford Crown Victoria with 120769 miles, Automatic Transmission, 2 wheel drive (rear wheel drive I believe). I had not noticed any strange sounds or fluid leaks, but I Just purchased this car used from someone who I believed to be reputable. When taking the car for an oil change the day after purchase. The mechanics informed me that, among other fluid changes needed, that the rear differential was leaking. They removed the magnetic plug and found the (what they called normal) metal filings, as well as some small chunks of metal. They acted quite concerned about these chunks. I researched this online and am getting mixed reviews. Some people say it is a major problem while others say it is nothing to worry about, to just replace the fluid in the differential. PLEASE help, are these chunks of metal a big concern? I really cannot handle another junker car. Thank you in advance for any info.
Hi, Opiate4622. The metal filings are normal, but the small chunks could be a problem. You may definitely want to get it checked by professionals. If it's not making any noises or leaks, it could be postponeable but I don't think I would push it. It's not necessarily a junker, but it will be if you don't get it looked at. Changing the fluid isn't that hard, but if you're finding chunks, I'm not sure how much longer you're going to last without having it serviced.
Only real way to find out is to take the rear differential cover off, and that includes draining the fluid buying new fluid and a new gasket and a little time. But I'd take it off and look inside for any damage or take it to a shop and have them do it for you.
