Noise from the rear...reward if problem resolved...seriously

My 2014 Tacoma started making a noise not too long ago and I am at the point of losing my mind. I have poked and prodded this vehicle for potential issues (obvious and otherwise) with no luck. I’ve attached a video here. This issue only occurs at speeds below 30ish. The bed liner is not loose. The spare chain is secure and has been checked. When in the truck, it sounds like the noise is that very rear of the truck. Anyone that has any ideas they are willing to share, I am completely prepared to send out a brand new YETI Tundra 35 Charcoal cooler if it resolves. For real. I’m desperate.

Video has to be hosted elsewhere to link, can’t imbed. Upload to YouTube, Vimeo, etc.

 

I don't see a video.

Rear shocks. TRD shocks are known for this.

Please ship to Canada.

 

I do like rewards.

 

Without seeing the video...

Do you have a lift installed? Did you install axle shims?

I don't want the cooler but if it's a knocking noise from the rear shake the bed and check the front passenger bed bolt connected to the frame. It'll work itself loose and rattle as you hit bumps. It's loud as shit.

 

Have a friend ride in the bed, since it is low speeds. Should help you corner it quick. Or better yet, ratchet-strap them to the undercarriage

 

Whenever I need a laugh, I come to this place.

 

Does it only do it when you go over a bump? If so, check to make sure your rear bumper is tight. Also remove anything you might have inserted into the receiver hitch. You might also check your ubolts and shock mounts to make sure everything is tight.

 

Now that there's a video I stand by what I said. It sounds like the bed flopping around.

 

Dude

 

Sounds like shock mounting locations are loose

 

is this a late April fools joke?

 

Noise from the rear...

Stop eating beans.

where’s my reward? Hah.

 

Have you tried turning on the radio?

Do you have a canopy or tonneau on the truck?

I'd start with checking the bed bolts to see if you're having this problem:

Then I'd start checking all of the fasteners of plastic things in the bed, especially if there has been a tonneau or canopy installed in the past (or present).

 

Have you swapped the back tires with the front to see if the noise changes with the tire re-positioning?

Also, wheel bearing, universal or rear-end gear noise?

Try adding weight to box (at least 500 Lbs.) to see if noise level changes.

Lastly, try running in lower gear to see if noise level changes.

Good luck, these type of issues can be most frustrating!
