It is hard to guess at a noise without hearing the noise first hand by being able to drive your truck. U joints in the drive shaft should be easy to diagnoise. Drive the truck experience the noise. Pull over where safe and slide under the truck and lubricate the U-joints with a lubricant like WD-40 flood the joints, drive the truck and see if the noise then disappears. If it does the u-joint is bad. Shocks never make a "squealing sound". Shocks can cause a thumping sound or a rattling sound if the bushings are bad.

squealing sounds to me like a belt prob. does it squeal when ever engine running or only when u r driving. if it's chirppy sound it would be a suspension issue. most moving mechanical parts grind more than squeal. i have '03 f-150. worst squeal i ever had was a broken parking brake. it was nasty. some thing else to consider(brakes). if loud squeal prob. brakes.
