I read through some of the posts and want advice in my situation.

I recently bought a 2004 Coupe a few months ago with 15K on it - mint condition with no accidents. The car seemed to have no real issues except a CD player that skipped on bumps, a bad speaker and the common driver side squeak on the bulkhead.

I have put 5K on the car and last week I pushed it up to 80-90 quite a few times on the highway. It was then I noticed a differential sound with light pressure on the accelerator - I am pretty sure it is the differential based on the sound and symptoms. I probably have one of the dreaded bad rear ends and it is just showing up now. At 65 to 75 I do not think the oise is present but I am sure it will soon become evident as time passes.

I will review the car history when I get back home to see when the car was actually first sold..I am the third owner and a dealer was the second owner. It was stored for quite a while.

What are my options since the warranty has probably expired!!! I was thinking of writing to Chrylser and explain the issue and offer a payment for labor if they supply the part...yeah..fat chance.

If I went with a new differential what are my options and costs? 2K would not upset me but more would make me think more about that Mustang 5.0 I originally was looking for. I don't need this car for commuting so a long repair is not a problem either. Until I drive it some more at 75 I don't know if it is a problem but it will always be in the back of my mind.

Thanks, PDW
