so I took it to the dealer, they admitted fault (told me that they did not add the friction modifier causing the lube to break down from heat. once the lube broke down the barings and gears ended up getting chewed up). The dealer can not fix it because they are on the Chrysler close list due to be shut down on June 9. They did however, recommend me to another Jeep dealer that was not shutting down, but would not fix the mistake for free since it was not their dealer that did the damage. The new Jeep dealer quoted me a price of $2900 for parts, plus labor and freight. They wanted to replace the rear end with a used one (because they didnt know if the axle was ruined), the only used one they could find was located in CA, I live in GA. So, I decided to take it to a powertrain expert in my area that does work for Dana. They quoted me a price of $1500 covering parts, labor and freight. After tearing my differential down they determined that all the guts needed to be replaced, and my axles were still good.
