Why does your explorer make a roaring noise in back?

A roaring noise coming from the back of your Ford Explorer may indicate several potential issues. It could be related to worn-out wheel bearings, a malfunctioning exhaust system, or problems with the differential. Additionally, tire issues such as uneven wear or improper inflation can also contribute to unusual noises. It's advisable to have a mechanic inspect the vehicle to diagnose and address the problem accurately.
