Last night my truck started to develop a sound similar to when the hub bearing has gone out and is rotating. So today I lifted each wheel and shook it and rotated each one to see if any where making the noise and none were.

I don't have the OEM undercarriage rock plates on it so as I've seen in other postings it's not that.

It drives fine, you can just hear the sound when starting to drive and while driving the rotating metal sound that a wheel bearing makes when it is going out. Could it be transfer case related? Like I said it drives fine, no clunking when changing gears.

 

Somebody mentioned something in another post about a drive shaft carrier bearing, but I didn't thing deuces have those?
I'd also thought about brakes? Pad down to the rotor?
Maybe jack the truck and try to spin a tire to get the driveshaft turning to see if you can duplicate it that way?
Good luck, let us know what comes of this-----

 

Yeah, I thought the brakes too so I did jack it up and rotate but I couldn't reproduce the sound unless driving. Also, I don't feel anything odd when braking.

 

Check underneith you might have ran over a (Smart Car) and your draging it along.........

Check your oil in your front axle, see if have any metal in the lube, also check your hub bearings and driveline..........

Hope this Helps..........Rick

Check the dust shields on your brakes...

 

you can try jacking all wheels up on jackstands. start it and place in drive and let the wheels spin . you may need a person out side the truck to help . just make sure you stop the wheel spin before you put it back in park. this is what we do to find a wheel bearing . i hope this helps

 

Thank you everyone for your suggestions. I'm going to see if I can use my friends shop so I can get the beast up in the air and hopefully I can track it down.

 

Is it a higher pitch sound than a wheel bearing? Does it go away after you've been driving 20 or minutes?
Mine is doing and my mechanic said they have seen quite a few cases where the seal on the wheel bearing is bad and causes the sound. When it gets hot from a long drive it stops making the noise. Unfortunately, the seal and bearing are all one piece, so you have to replace it all anyway.

 

It is kind of high pitch and I hear it mostly at low speeds and there's no vibration felt through the steering wheel or floor. It's going to the dealership on Saturday so, we'll see.

Thanks again everyone!

 

My new bearing sets just got here from UPS. I'll get them on next week and see it fixes the issue.
