Hello, I have a 92' 4x4 sr5 4AT that has been having what me and my friends have coined "the phantom squeak" for about 6 months now. The noise is a high-pitched sound, whose frequency and spacing is relative to the speed/rotation of the front tires. For the first 2-3 minutes of driving there will be no squeak, but then appears shortly after and abruptly so. On very cold days / mornings there is no squeak however, and the truck runs and drives fine. The odd thing is it gets louder the slower I go and fades when pressing the accelerator, going up a hill, or through a ditch. I don't drive the truck especially fast or hard, except for when its snowing and need to get up my driveway. Any help or input is greatly appreciated and welcomed, many thanks in advance!

 

Bad u joint possibly

 

Apologies for such a late reply, but I figured it might help out someone who needs it. Issue turned out to be my central carrier bearing going bad, in particular the rubber that dampens its vibration. Installed a new one last year and the problem still remains fixed, however another good thing to look out for if this doesn't solve the problem is a cracked, warped, or unstable driveshaft.

 

Hope you find the issue soon! Keep up the work!
Edit: Thanks for the update.
