02 durango awd hummming noise at 40mph, tranny was rebuilt 3000 miles ago, fluid is full, it sounds like its coming from the middle to the front area, gonna have the wheel bearings checked and t-case and front diff checked in the a.m. it seems to stop once i lay off gas pedal i hope its not the tranny

 

Sounds like a carrier or pinion bearing in one of the differentials.. Also could me gear noise from the differential..

 

had the mechanic that works at the dealership take it for a run says its not the tranny so if it gets worse ill bring it back to him, it maybe just bearing noise but gonna do some further looking into

 

Check the U-joints on the drive shafts, also check the CV's on the front end.

Does you durango have a 46RE or 545RFE transmission? If its the 46RE, Yes the noise is coming from the transmission. Because there is a large bearing in the overdrive unit that goes bad and sounds like the problem is in the transfer case or diff.

 

its a four speed with overdrive and the tranny was just rebuilt 3000 miles ago the bearing couldnt be bad? and if it is what will happen if i dont fix it i really dont have any cash

 

Nick,
I have the same thing going on with my truck. I am pretty sure ti is my Front DS being bad and my u-joints are probably bad as well. I would check the front DS.

Put the truck in park, get under the truck, and try to turn the front DS by hand, if it moves at all, it is bad.

 

Okay, so its the 44or 46RE transmission. Its an easy fix. Only the overdrive unit comes off to make the repair. What type of warranty do you have for the rebuild transmission? If the transmission was replace at the dealership, reman trans are 3years or 100k. If they overhaul the trans, its 1 year or 12k. Also adding the problem noise didn't start until after the transmission was either replaced or a rebuild. You can also tell who ever worked on the transmission, that you got is from a dodge transmission tech of 25 years. Also ask the tech, would he continue to drive this durango if it were his with his kids and wife or mother?

 

I have told someone this before just to get them out of my hair, of course I was just a AAA guy who had spent too long dealing with a battery issue. I wish people would answer that question truthfully, though most times they don't.

Hey Master_tech, the 99 Durango 5.2L 4wd, does it have this bearing?

 

well the story goes i bought it from a dealership, the previous owner had the tranny rebuilt at aamco, and i believe its the 46 not to sure will have to grab vin and look it up, and ill check the drive shaft to, as for warranty no clue, and if i have to do it myself how hard is it?
