I know there is another thread about this, and a few people and I were talking about my whine as well wondering if it was the same, decided to start my own thread so I don't hijack his. I haven't listened to this video yet, but you should be able to hear it. Windows up at around 50-60mph

Sounds like exhaust but it is not. I have stock exhaust and sounds nothing like exhaust when actually in the truck. It is a lot more high pitch than that.

 

I will probably get you guys to proof view it for me, when I get around to changing the u-joint, just need to find the time (and warmth) to do it. I used to pull Drive shafts when doing medium and heavy duty towing, comfortable with that, but man can it cold under there!

Spent the day today in 33 degree weather in Ice/Rain at the range in matches all day, so was unable to do it today (not that I would want to) but I will get around to it

 

Sounds more like a "hum" to me, not a whine.

Sounds like a classing U-Joint. U-Joints are classic to get worse at specified speeds like between 60-70 MPH being the worse. You let your foot off the gas and it then changes the geometric torque on the bearings because now instead of forcing the drive train to push you you take your foot off the gas and let the drive train slow down and drain into your motor.

 

So I was thinking right, it is my u-joints more than likely. Thanks Hydra, will get around to changing them soon. I hope

 

I agree with hydra, sounds like u joints. They can be annoying little buggers.

 

I wouldn't want to do u-joints in 33 degree weather either,at least you have it figured out and know what you're up against when the weather breaks....hope it
all goes well when you do get to it....

 

Mine makes the same noise. Is there any other way to tell its the u joints before I was to tear into them. I'd hate to work on them and the noise was still there.
