Help me identify driveline sound??

So 2012 Baja, 1inch toytec spacers up front, 1.5AAL in back. I suspect the carrier or a u joint. Just wanted you all to take a look. Not much play in the carrier, and all the ujoints seem tight. Going to check over all the heat sheilds, but something is loose... Take a look at the video, no gopro, but a cheap little camera that catches the sound good. Any insight would be appreciated!!! Thank you all so much!!

So heat sheilds are tight, o2 sensors tight.... Will keep checking!!

 

Bump

 

Anyone?

 

That's what I was thinking, even though I'm only 50k.. will be replacing myself next weekend, we shall see! Thanks for the info!!

 

I'm no expert, but if I had to guess, I'd say it kinda sounds like a bearing is dry.

 

Probably one end of a ujoint!!

 

Can hear it more in the cab under acceleration, and in the video can hear it while costing.

 

You know you getting active in tw when @ChadsPride like rolls through your thread!!

 

Ya, the exhaust muffles the sound a bit, but I heard it. When's the last time you greased your zerks? That would be the easiest thing to check first.

 

And before you know it, you'll get sucked into his BS th....I mean...."Build" thread.

 

Greased then about a month ago... They took quite a few pumps until grease came out.. I'm thinking about it now, I bet at least one of them was and still is dry...

Yeah, reading through his build now... Dammit!

 

I couldn't hear anything, but I'd start with greasing all 5 U joints, since that's cheap and easy. Then I'd spritz some WD40 in the carrier bearing. If the sound goes away, it's likely that.

 

Forgot about the wd40, will give that a shot

 

I was also chasing a driveline squeal, but never ended up solving it before I traded the truck in. Good luck!

 

I think this is the best solution yet lol

 

Sounds like bearing noise.
