Loud Squeaking Noise

[Rebelt]

Hey all you experts need some help diagnosing a loud squeaking noise. I've started to notice a loud squeaking noise coming from underneath the rear of my ZR2 HD. I only notice the sound when I'm traveling low speeds 14mph or slower. I don't hear it when I apply the breaks or when I go over bumpy roads. My truck has 2,000 miles on it. This sound is driving me crazy. Any help will be greatly appreciated.

Check to see if your spare tire is cranked up and solid.

Make sure you're heat shield between the exhaust and spare isn't rubbing.

May need to check the torque and alignment on the springs where the u bolts connect to the axle.

Check the fluid in the rear differential.

May have a bad wheel bearing from factory.

The speed may only be coincidental, in that you can hear it with less vehicle and road noise.

Thank you for reply. I checked the spare tire and heat shield, all are solid and heat shield does not appear to be rubbing. Dif fluid is good. Ill check the u bolts. The bad wheel bearing from the factory is concerning. Thank you Axe
