I have a droning sound...

Replaced last summer as it finally blew a hole in it. Stock with new gasket and hardware.

 

Does it change with speed?

 

I start to hear it around 30. Gets loud between 50-60, and quiets down a bit by 70 but doesn't go away.

 

You sure it’s not the diff?

 

No, I'm not. I did have the rear end up on Jack stands, idling in gear and didn't hear any strange noises in the diff or the axle bearings with a mechanics stethoscope.

 

I'm thinking that I may drain the front diff and pull the CVs out.
Thoughts...?

 

Ooooook, I think i found it. I believe it is the passenger side wheel bearing on the back wheel. I noticed yesterday that when turning to the right the sound diminished and almost went completely away depending upon how hard I made the turn. I'd really love another pair or trained ears to confirm this though before pulling the axle(s).
Now the question is; how much does it cost to have the bearing replaced should I bring them a clean axle? Inquiring minds want to know. Lol
Any Toyota techs in the Boston area...?
