Car made a whining noise at 35-45 m. P. H. Bought new tires and alignment. It turned out to be the rear differential. It was rebuilt for $1200. One week later it made a higher pitched whine. A Chrysler employee told me that beginning in 2005, Chrysler outsourced for cheaper bearings,and they were defective. He said they are no longer made. A whole new diff and axles had to be installed for another $2800. It still whines at all speeds now. Chrysler said "live with it!', and expect it to fail repeatedly. The case had been set wrong at the factory as well. There are hundreds of these cases on-line,but Chrysler refuses to acknowledge them.
Jerking in differential, dealer said they don't know what the problem is, it has been like this since I bought it new in 2005.
Consumer stated: the seal was completey gone in front of the differental. No lights came on. It was making a grinding noise like rocks were in the wheel.
I was performing an oil change on the vehicle. As soon as I crawled under it to start, I noticed the right side of the front differential where the axle tube mates, was covered in diff oil. I took the vehicle to the dealer and was told it was "normal seepage". I find it hard to believe a gasket can only hold fluid for less than 6000 miles before leaking. Dealer refused to correct it.
