For a 2012 Ford Escape. A couple of weeks ago, I started to notice a fairly loud knocking noise from my rear right wheel. What’s unusual about it is that it only happens when actively accelerating (it completely stops when I remove my foot from the gas. I don’t need to apply the brakes.) and it seems to start up at around 20MPH and then speeds up with acceleration until it stops at around 30MPH. I have noticed no other symptoms such as vibrations, loss of power, difficulty steering, whining, pulling, or grinding. I also haven’t noticed anything leaking from that area, either.
Any help pointing me in the right direction would be greatly appreciated!
