★ Top Answer
The primary reasons why your Ford Focus might make a humming noise when you accelerate are usually related to issues with the wheels and axles. The main culprit is typically a failing wheel bearing, although problems with your CV axles could also be a factor. It can be tricky to pinpoint the exact cause, as similar symptoms could be caused by a faulty alternator. Have you had your car checked for diagnostic codes yet? Your Focus might be providing clues about what's wrong; you just need to pay attention. If not, the best approach is to try to determine where the sound is coming from - is it the front or rear, left or right side? You can lift the car up and check if any of the wheels have play, which may indicate issues with wheel bearings or ball joints, leading to humming during acceleration.
