Why does the ford edge make a humming noise?

A humming noise coming from Your Ford Edge could be an indication of an issue with the wheel bearing, brakes, or the engine. If the noise increases when accelerating or when turning, the wheel bearing is the most likely culprit. You may also experience a clunking sound when riding over uneven roads, steering wheel vibrations, and/or grinding noises with normal driving. The typical life expectancy of the bearings iS85,000 to 100,000 miles under normal driving conditions. The cost of replacing them ranges from $60 to $100 for parts. Labor will cost an estimated $160 to $200. You want to be sure new bearings are appropriately installed which includes the use of the right tools and torque so that they last as expected.
