Weird noise. Want to make sure its not serious

So I didn't want to title the thread "strange noise" because no one will look at it.


However recently, as in for about 2 weeks when I drive the truck with the windows up, music off and A\C either off or on the first notch I get this strange noise from somewhere in the truck. I am assuming its from the front since I can hear it.

It sounds like little birds chirping, quickly and in a very hi pitch. It does it the same speed if I am slowing down, speeding up, and cruising. Something needs lubrication? I just want to address it now rather than 12 hours away from my garage pulling 12k lbs.


Thanks

Im thinking that it's a possibe u-joint that might be starting to fail. Your factory u-joints do not have a grease fitting. The only way to fix it, is to replace it. 9 times out of 10, the rear u-joint is the first to fail(the one on the yolk), then work your way forward by checking the other u-joints. In an extreme case, my F-150 had plenty of slop when I twisted the drive shaft back and forth. On my F-350, theres was no slop, but I replaced it, and cured the problem. -Trevor

so vehicle speed has nothing to do with the sound changing ?

may be the blower motor, is the noise present when sitting still ?

u-joints don' rotate/move sitting still.
the WD-40 will probably just wash out whatever grease left in them

I tried it again today, they might actually be the ujoints. I started the stop and start game to see if I could isolate the noise, and I am just hearing it when I am sitting because I hear it all the damn time and its stuck in my head lol

Blitanicle99, on both of my Fords, the noise from the u-joint slowly got worse and worse. But on my friends Chevy Avalanche, his u-joint started to act up, and within a 2 week period, I couldn't belive how much louder it got in that amount of time. I pulled an 8000 lbs every Friday during the summer with my F-150 that had a bad u-joint.(not smart I know) You should be able to make it back to your garage without an isssue. Of course if you did break a u-joint, put your truck in 4wd to get to a safe spot,(I'm sure you knew that already.) Hope this helps you sort out your issues. -Trevor
