ABS and Break lights are on. Why would I need to replace the rear differential?

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Seeking validation for your diagnosis on the Internet is not likely to be possible or even valid. A hands on inspection has revealed the diagnosis. Certainly, should you want a second opinion - reach out to another shop near you to get one. See below. Without being able to inspect the vehicle first hand, it would be difficult to speculate what has happened and what needs to be done - so get that second opinion to feel better about the path forward whatever it turns out to be. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
