Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I am Mike, welcome. I'm reviewing your question.
You should first check the lubricant level in the rear axle. Other than that is the noise is coming from the rear differential then you could possibly have a worn ring and inion gear, worn bearings, whichever though ,the axle should be serviced.
I did find a procedure though you could try to check the Hydra-lock. Look at the bottom of the page I uploaded.
The nearest Dodge dealer to you might be
Cannon Chrysler Dodge Jeep Ram

Actually that website is down.
A locking differential.
kindly leave me a positive rating, so I get credit. After all, you have already made the deposit.
