Squeeking noise down under

[JThelen]

recently my truck has been making this almost bird-like chirping noise when i accelerate. the noise is coming from under my rig towards the back i figured maybe it was my rear driveshaft, or yolk just needing a little lube but WD-40 did absolutley nuthin, anyone ever delt with anything like this before?? Thanx

Well, i recently had a squeaking sound coming from the rear drive shaft and would only be really noticeable when driving at slower speeds. I diagnosed it as a faulty universal joint and replaced it which eliminated the squeak. Does the squeaking sound get quicker as you accelerate to a point where it practically goes away?

ya thats exactly what happens it start slow u know when im rolling and as i pick up speed the driveshaft ya know rotates faster and the sounds speeds up as well but like u said itll go away when i get to higher speeds

Dunno how this constitutes a emergency but by chance what is the condition of your rear differential fluid? You could have also have a chipped gear which is causing the noise.
