Differential Unit problems of the 2008 Chrysler Aspen

I recently bought my chrystler Aspen and as I was driving down the road I noticed a clunk on the rear end. I checked to make sure the spare tire or muffler wasn't loose and even took it to a local shop where we found a bolt located right at the rear differential that appears to be loose causing that clunking noise. I went online to see if any other chrystler owners had the same issue and found out that there has been certain Dodge and chrystler vehicles affected and even recalled for this same issue. I also read online that driving with that bolt being loose could damage the differential and cause it to lock up make the whole truck to stop very suddenly causing the driver to loose control of the vehicle. I called 2 different local dealerships and explained the issue and asked them if my vehicle had a recall like many other similar models had,but they told me there was no recalls on my truck. I'm concerned for my safety and my family's due to my truck's condition and I would like to let chrystler know this poor workmanship could cause a serious if not fatal accident for me and my family if not resolved.

Rear pinion nut backed off causing lost of fluid from the differential to leaked out. Talked to Chrysler and they said this model was not on the recall list even though the description fits to the letter on what has happen on those covered on the recall. Had to get repairs done at pep boys since no dealerships are open on Sunday or Saturday afternoon. Replaced pinion seal and add fluid to differential, torque nut. Is this going to happen again after 50,000 miles or other people.

Noise and jerk (sometimes pretty violent) during acceleration after slowing down. Took to dealer and they checked u-joints (ok) and said the differential seal was leaking and nut had backed off. . . . . Tightened nut and replaced seal. Still having problems with noise/jerking. They say it is still a differential problem and we are trying to get the extended warrantor (fidelity) to agree to pay before we fix since it will be over $1200 to fix. I feel this is the same issue that we received a recall for the differential in our 2005 Dodge ram. Chrysler should look at this.

The contact owns a 2008 Chrysler Aspen. The contact stated that the vehicle stalled while driving 55 mph and made a loud noise. The vehicle was taken to the dealer who inspected the vehicle and stated that the rear differential and the rear axle failed. The repair would cost him $2,600. There were no recalls or warranties. The manufacturer was contacted and offered no assistance. The failure mileage was 65,000.
