3rd Gen Poll: Rear End Noise howling when feathering throttle

So engine RPM makes no difference, or very little difference. I wanted to confirm this. Thanks!

 

And the same for me as well.

 

Does it change with loads in the bed?

 

I've noticed slight changes. Seems louder, and the affected speed range increases a bit with heavier loads in the back.

 

Same. 4th,5th, 6th. Only difference is the engine is roaring a bit louder at 3 to4k tpms so you hear that a bit more

 

Just got my 2020 back from receiving a new diff. I’m curious if there will be any improvement.

 

Mine was good for about 30 miles then right back to the same old noise

 

They didn't give you any shit for those wheels/tires and lift? Lol. Truck looks good! Links to other pics? (Mines the same color 2020)

 

30 miles... ugh

 

Thank you!
Nope, they didn’t push back one bit with the lift and tires. I was super picky with inspecting everything when I picked it up. They trashed my old wheels with an impact gun.

Here are a couple of other pics. I just installed everything about a week ago. I love how it turned out.

Found something interesting...

This dude did a regear to 4.88 NITRO and you can definitely still hear the howl. Clearly regearing doesn't solve it.

(tune to 6:12)

 

To me that’s a different howl and he is not feathering the throttle.

 

Interesting, yeah mine happens feathering and when you're on the gas accelerating or to hold speed. It sounds pretty similar to the video, although given that I can't hear it in real life, its hard to tell.

Regardless, they are completely different gears, not setup by Toyota/HINO, and they still make noise at roughly the same speed range. To me, it reinforces the "its just NVH" argument.

 

Huh? I hear noise. Howl???

 

Well however you define it, it's damn annoying lol

How would you define the noise in the background starting at around 6:12 in the video?

 

Crappy microphone?

 

If you fast forward to 7:47 and listen for a few seconds, you can hear the diff whine/howl/whatever peak then let up as he slows down. It's definitely a gear noise... and very similar to what I hear in mine. His might even be a little louder.

 

I hear it. I guess it's not bugging him.

 

Yeah. Thats why its nice to have video of this stuff... different people can tolerate noises differently. When someone says "no mine truck is silent", you kinda have to take it with a grain of salt. They may have the noise and not care or even recognize it.

Helps put things into perspective IMO

 

Could be the tires in the video, although at one moment it does sound very much like mine howling...only for a brief moment in the video, though. When he slows down to stop you can hear the tires. Just too hard to judge from a video recording to compare with our trucks on real life...but good try.
