My 2011 ford f-150 has a knocking noise coming from under

Customer Question

My 2011 ford f-150 has a knocking noise coming from under the rear bed. I had a friend listen for it. I was turning out of the gas station when I heard a creaking noise, then it turned into a knocking noise. it makes the Knocking noise in forward and reverse. The only time the noise stops is when the truck is slow like in a walking speed.

Do you get a vibration as well?

Is it 2wd or 4wd?

Automatic or manual?

Welcome I'm Chris aka Moose

Different tech here

You mentioned it does not happen at walking speed does that means it occurs in drive and reverse not moving or only when going over say 5 mph in drive or reverse?

If it occurs sitting still then I suspect a possible exhaust hanger or shield to blame or the rear trans mount. Can you check those?
