    Hello gents,

    My Tundra (60k miles highly maintained and taken care of) has this knock or clunk as soon as I start the truck. The vehicle is stationary in park with e-brake on I know this is vague but it almost feels like an engine mount, wondering is any of you have input or thought on where I might focus or have experienced anything like this.

    It does seem to be coming from the right side of the engine bay (I could be wrong but I’ve tried to pay close attention)

    The truck also does the same knock-clunk when I accelerate from a stop.

    To be clear I am not taking about the brake/abs system clunk that all tundras have, that we just all deal with.
