2001 Expy Knock on acceleration
Howdy everyone, I have a 2001 Expedition 4.6L XLT, rwd, 186K miles. A few weeks ago, while driving, I heard a thump toward the front of the vehicle, then the knocking started. It is a definite metallic knock which only occurs above 1500RPMs while accelerating. I was doing ~20-30mph at the time...- VictorDuwon
