Could it be wheel bearings??????
 

I took my truck for a drive tonight to see how everything that was put in is working, and my number one problem is two noises. one, changes with speed, and is like a high pitched, almost rubbing sound, the other, is just a high pitched ringing sound, im thinking that its the wheel bearings because the main one does change with speed, what other problems could it be that change with speed? does anyone know of any??
Thanks. Need help!!

center bearing in the drive shaft will change with speed

Are the wheel bearing one of the things you were working on?

no they are not, im leaning towards them as the problem though.

Might as well just go ahead and change the brakes, get the rotors turned, and put some new ones in.

That or just take it all apart and regrease them/replace just the bearings.

Still trying to figure out your other problem, but that's requiring more coffee...

front brakes ok?
does it go away when the brakes are used?
squealers hitting the rotors?

:dohh: Why didn't I think of that. Too much into the bearings I guess.

What truck are u working on and what parts were replaced that you were checking?

As far as changing the wheel bearings go... you might as well go head and do it, as a precautionary measure, if you haven't done it in a while.

However, I had the same weird noises.. thinking it was tire noise,(sometimes odd wearing tires make special noises too)

I did change my wheel bearings, and that cured pretty much all of the noise...it's all metal you'll dealing with, and sound vibrations do have a way of resonating through everything... good luck...

I would start with bearings..;)

How about just jack the truck up and spin one wheel at a time to try and see which one is/isn't making noise?

thanks for all the responses guys, i tried it all and it turned out to be the speedo cable coming from behind the cluster that was changing with speed!
