and yet another problem... This squealing noise is coming from best i can tell anyways from rear end drivers side. The noise sounds just like a soft brake squeal, real high pitch but not very loud. no grinding or scratching sounds. it does slightly change tone as the wheels rotate. makes this noise anytime the truck is moving, forwards, reverse, turning left/right, neutral. keep in mind im not applying the brakes. when i do apply the brakes the sound doesn't change. i know i need new front brake pads as well. also im not 100% thats where the sound is coming from, but any insight on where to start would be great.

 

check your u joint on the drive shaft mine did a bunch of squeekin before i replaced it...it probably would have come apart within a week if i didnt change it when i did

 

sounds like it could be a bearing issue

 

anyone point me in the right direction to research/diagnose this?

 

sounds to me like it could use some grease or its going bad. but it could also be the u-joint like heckman said

 

the best way to tell is to jack up the wheel and turn it and it would make the noise you hear or a roughness in the wheel as it turns

 

grease. that sounds inexpensive. does that go for front and back? im a total newb on this subject. and google search yielded nothing in line of a how to/diy, pictures or anything.

 

wheel bearings are behind the rotor and if they arent packed properly they could begin to make a noise, another thing it could be bad sometimes it will start to make a squeally noise when they go bad the best way to test it is to lift it up and spin it and see if it makes the sound or just while its on the ground grab the wheel at the top and shake it really kinda hard and it shouldnt pull in and out if it does they could be bad.

 

If I were you, the first thing I'd do is go to the parts store and by a Haynes manual.
