my truck has made this damn sqeaking noise ever since i bought it. whenever i go from park to any gear, or take off from a stop, it makes a sqeaking/creaking noise. you can kind of feel possibly the rearend shifting or something, but i've checked the U-bolts and they are tight. any help would be appreciated.

That's just your brakes. It's not a big deal. It from the load placed on the disc and brake pads.
If you depress your brake pedal really hard, then switch from park to drive or reverse. It shouldn't be all that noticeable if any. That will tell you if it's coming from the brakes.
You have no sig. What kind of truck, what year, and how many miles are on it??

99' GMC 1/2 ton, 4wd, ext. cab, 5.3/auto, 186K. i just use it for a work truck, and to haul my car, but i want to keep it nice and mechanically sound.

 

My 99' had the same noise. It was the slip yoke that goes into the transfer case. Theres a TSB out there for it that has a fix that involves either greasing it (Temp fix) or installing a nickle coated version. I got mine replaced and it took care of it.
If you do a search for it I'm sure you'll find what I'm talking about.

 

my brakes did that

and my shock extenders (lowered 4/6)

replaced brakes and tightened shocks

no problem anymore
