    I've been driving myself insane trying to figure out where a bizarre knocking/binding sounds is coming from on the front driver side of my 2011 4Runner SR5.

    The noise is very apparent at low speeds, and can be felt through the floorboard on the driver side. It can be replicated to the best of my knowledge by just pushing down on the front driver side of the bumper.

    It does not go away when I engage four wheel drive.

    There is no play in the wheel bearings lateral, or otherwise(I'm at 187k so I'm changing these anyway)

    The body mounts seem to be in decent, and I can't feel any play when I have my buddy shake the vehicle.

    I have changed both the inner and outer CVs, and plan to change out the needle bearing on the driver side of the dif with a brass bushing from East Coast gear supply.

    I did not notice any rounding of the bolt holes in the knuckle, but this is where I can most easily feel the the vibrations of the noise. So getting a new one of these is not far from my mind either.

    Any suggestions would be welcome, I've been battling this on my own for about a month now.

    Edit: Here's a video to more accurately display the sound, while I load and unload the suspension.

    See if your driver side wheel well cover is rubbing against the metal. It's a known issue, where the plastic clips break and make noise.

    Since you can replicate the noise merely by pressing on the bumper, it's more to do with a broken plastic piece or something similar rather than suspension parts.
    But you could also hand sway the car left to right to see if it makes the same sound.
    I have a 2011, for reference.

    I'll have another look around to make sure I am not making any hard contacts with the wheel well.
    And it's probably not a bad idea to re-torque my suspension. I still have less than 4k miles on this suspension, and performed the prescribed re-torque within the first 300. I come from an aviation background, so all of the bolts/nuts torqued are marked with torque stripe, and I have yet to see evidence of a slipping torque. But mistakes do happen.

    My primary concern remains that it happens every 2-4 tire rotations when on flat ground, not only when I load the driver side suspension.

    Thanks for the feedback regardless!
