Noise in drivetrain - 06 Yukon Denali AWD

[nelly17]

Hey guys,

Im a bit stumped and dont want to throw a ton of money at rebuilds and such until i narrow down that this is.

I have a growl that begins at 45-50mph.
Its in the Driver front side.
It is only there during cruising or acceleration.
Speed dependent and not RPM dependent.
I just got the truck so everything is original.
U-joints "look" ok.
It sounds like the front diff from where it is coming from.
Tires are new and balanced
It shifts perfectly so I highly doubt it is a TC or transmission related.

Any one have these symptoms and figure out what is was? Originally I was thinking u-joints on the driveshafts but it is clearly coming from the front.

Thanks in advance.

Sounds like a wheel bearing going out.

It sounds like your front differential carrier bearings are bad. Check out the links in this thread, Hopefully they can help.
