I'm getting this strange noise coming from what sounds like the front of the vehicle. It's like this weird metallic rubbing/winding type of sound when I let up on the gas pedal. I also notice but not 100% sure, appears to decelerate quickly with this strange noise too. I can also hear it when the vehicle gets up to speed past 40 and the sound correlates to vehicle speed. When I slow down from a stop I can hear the weird sound but at a slower speed as the vehicle slows down.

I've done the following:

replaced the rear diff, transfer case, and front diff fluid with Peak synthetic 75-90 gear oil. Had a very small tiny piece of shaving from front diff but that's it.

replaced the rear diff with a used one from a 06 with 74K miles. Rear diff whine appears to be better now.

Inspected front wheel hubs both move smooth/no gritty or roughness, and no play when shaking the tire from the 12 and 6 position.

I inspected the front brakes - guide pins, caliber, pads and rotor all good.

I don't get any strange vibrations when braking or turning. The engine runs smooth and shifts normal.

None of the links provided works.

Does the noise disappear or changes when shifted to neutral while coasting?

I'm so sorry. It appears there were gaps when I initially put them in. They are fixed now and you should be able to view the videos on Youtube. Just copy and paste the links into your web browser and they should work now.

It's consistent with wheel speed. So if I'm up to speed above 40 while accelerating I can hear it most times. I can also hear it when I decelerate by taking my foot of the gas pedal.
Thanks.

Never mind about that because I don't think it is going to help much.

You did not answer my question. What I am trying to ascertain is if it is transnmission related.

Ok, I'll drive it on my lunch break by placing it in neutral when I hear the noise and report back.

I think that the video can help because you can clearly hear exactly what that noise is.

Thank you

That would mean that it is not relateed to the transmission and for metallic grinding noises, it could be from the backing plate of the disc rotor. Ensure the plate is ot too near the rotor.

Hey JASONS760, it sounds like it could be the tires? Have you tried rotating them front to back?

Best, Ken
