Whistling/Squeaking Noise starting at 30mph

[mctwist77]

So I have a whistling/squeaking noise which starts at about 30 mph and the noise gets "faster" as I accelerate. It sounds like its coming front the passenger side wheel. I can only hear it with my windows down, when the windows are up I cant hear it. I dont think its the brake pad wear indicator because when I hit the brakes the sound is still there. The sound is constant whether or not I have my foot on the accelerator, and whether or not I am in drive or neutral. My truck is a 4wd 98 Sierra with the 305. Any help would be appreciated, its driving me crazy. Also, the noise is not dependent on RPM, so that kind of rules out the engine making the noise.

hub bearing is going or gone.

Is that a difficult DIY?

 

[mctwist77]

Oh nvm, its the same as the wheel bearing. Its not hard

 

[mctwist77]

When those go isnt it typically a grinding noise? Not a squeaking?

36 mm socket for the axle nut remove rotor and caliper 3 bolts hold it to the steering knuckle and a few good hits with a deadblow hammer and it should come off

Fold the mirror in and try it, the drivers side of mine whistles in the wind. Hub bearings are gonna make more of a howling noise that changes as you swerve in the opposite direction of the bad bearing. Mine whistling drives me insane.
