I just recorded 20 MPG (my worst ever!) on the Jeep, and the grinding/humming noise is getting worse from the front end. It used to be a universal sound regardless of turns, but now I notice a distinctive vibration/pulsing sensation when I drive around turns. It seems to vibrate the Jeep whether I'm swerving left or right.
Quick history from other posts - my Jeep vibrates and hums now when i drive. The sound seems to match the rotation of the axles, not the engine or transmission. I replaced brakes and rotors and the right front wheel baring. I'm now thinking that it's the front axle shaft. I have a video of the movement and I hope someone can confirm that this looks good or bad.
Thanks for any thoughts.
