Took the wife’s Sahara for new tires the other day and noticed a noise I didn’t like coming from rear end. Took to dealer and sure enough, rear diff. is trashed. Evidently, some bad bearings from the factory and they were slowly coming apart. The worse news is, parts aren’t available it seems. They said at least 2 weeks. Oh, and guess what else, FCA would only pay for 1 week of rental. Dealer did step up and is providing a vehicle to drive although its not a Jeep. @JeepCares can you help with this and expedite???
