[SOLVED] Howling noise between 35-45

Got a couple Pics for you sooner than later my friend!

 

I'm impressed

 

I was happy to see them coming that way from the Factory now.

 

Mine just came in around the first week in February so I assume/hope it has it. I don't want Smitty to make me crawl under my truck to verify it though - it's dark outside.

 

That peer pressure! It's a bitch

 

Mine was made Early March, that was actually one of the first things I checked after I bought it.

 

Smitty this is all your fault but it was too dark to get a good pic. Mine does NOT have it and it's only 8 weeks old. Where do I get these things?

 

Well this sucks for me I guess. In one month I guess they started putting these in. Either that or they just missed mine with that stellar quality control...

 

Toyota Part Number 90950-01955

 

Excellent - I appreciate it. They really missed some obvious stuff with these trucks. I love it BUT the last couple of years has been a bumpy ride for Toyota.

 

OK, well, I'm an idiot. But, having said this, I did say it was dark. My holes are plugged. I was looking at the wrong part. I guess maybe I should now formally apologize to Toyota but since my rear diff still howls a middle finger to them will have to do...

 

No problem Bro, make sure you only plug those particular 3 holes on each side, I cant figure out why some would have them plugged and others would not, maybe they are flipping coins or something...

 

I just had mine done last weekend and this is what mine looked like from the dealer.

 

Good day. What a magnificent job! Bravo! I have a 2017 off road 4x4 and it has been addressed by putting three plugs into the culprit holes! By Toyota none the less. THEY WILL COME IF YOU BUILD IT! GREAT JOB SIR!

 

Nice sleuthing, but I wonder if plugging those holes cause water and silt to pool up inside? Wonder if fiberglass tape (the kind to repair drywalls Or something else like it) would be better for letting water and dirt wash out? It might break up the airflow noise just enough while letting the parts drain.

 

Not that I can see. There are or is another hole at the very bottom that will allow drainage. If that gets plugged by debris there is another hole above it to mitigate any build up of fluids.

 

Those holes come plugged from the Factory now, there are still 3 open holes too if memory serves me correctly.

 

The open holes are the ones that I am talking about. The "NOISEY" holes are plugged at the factory now. At least on my 2017 Off Road access cab.

 

I was just under my Taco to rotate tires and lube the drive shaft at the forward diff shaft, couldn't find fittings on the rear shaft.

 

I have some pics of the lowers on my truck.
