Is my 2013 Toyota Tacoma doomed? Lower end knock

Question

Hey y’all.

So.. I’m not even sure what to make of this.

I got this Tacoma (2013 2WD 4.0 V6) with 130k on the ODO. It currently sits at 155k. The sound I’m going to demonstrate in these videos has occurred since day one.

So far, it hasn’t become a problem. The sound however… well that makes me think I’m waking in egg shells. IMO, it sounds like a problem.

I’m hoping someone may be able to help point me in the right direction. I know videos (audio especially) isn’t easy to distinguish when it comes to engine noises. So any advice is welcome.

I get the sound after a start up and it starts to warm up. it’s everyday, not intermittent. If I rev up to 2k, I hear it up until I get to the 2k marker, then it goes away. On the wind down I hear it again.

I THOUGHT it may be a spun bearing. In my experience though, spun bearings get worse over time. This has not gotten worse, or changed at all. So while it still may be one, I found that odd.

I change the oil every 3k and use what’s recommended in the manual.

I’ve had the oil changed by shops as well, and everyone says the oil looks fine. I have not however cut a filter open or dropped the pan to check for metal shavings, etc.

Thanks again for any advice.

The first video is a little longer, the second video was during a drive. I stopped and got out real quick. Please disregard the radio lol.

If I knew the sound wasn’t pending catastrophic failure id Honestly just accept it. Until then though.. I’m just worried. Thanks for any pointers, y’all.

At 1:30 (video one) I rev it and you can get a better perspective of the sound. It’s the lower end frequency sound.

Yeah it kind of sounds like bearings are worn if you want to keep that engine I'd rebuild it sooner than later. Or I would just drive until it dropped and then put another engine in

Hey y’all.

I’ve got a 2013 Toyota Tacoma, 4.0 V6 with just over 155k on the dash.

when I’m in park I hear what appears to be a lower end knock. When I rev 0-2k RPM’s I hear what sounds like a spun bearing. however, when I’m in gear the sound is gone. It doesn’t knock under load or driving.

My question is this.. can rod bearings be worn? This would make sense for the sound and make even more sense because if it were spun… surely it wouldn’t have lasted over the last 30k miles I put on it after noticing the issue.

looking for any info. Thank you.
