Hey I bought my Bronco about 4 months ago and have had tons of problems. This one is the biggest so far. Issue is when I drive and get up to about 20+ mph I hear a loud grinding noise. I let of the gas sound goes away. Sounds in the front. Happens a different speeds. Truck still has good power, shifts fine and no slips. Its a automatic. When I hear it I swear it sounds like its coming from the front right. But hard to think this is a Hub causing the issue.
