So the other day, I was under the truck lubing/greasing up all suspension parts from the winter snow/salt. Lately I have had an extremely annoying brake squeak that only happens if you keep the wheels straight. If I make a hard right, it stops and vise versa left. I noticed when I did have the truck jack up, the wheels didn't seem to want to spin freely. When I spun the tire, I could hear the pads slightly rubbing as the tire rotated about 2 times. Is this normal? My drivers side seemed to spin longer, then the passenger. I'm hoping both Calipers aren't going out on me.

 

Could be a wheel bearing.

 

I don't think it's a wheel bearing, since the sound goes away when the brakes are applied. Don't wheel bearings make more of a grinding noise when they're going bad?

 

Not all the time. The noise goes away because your not allowing the bearing to move around. Jack it up and check for play. Keep in mind bearings can be bad, and not make a sound and be tight. If you're over 100K. I lean toward bearing.

 

If it were the brakes, I doubt the sound would change when you make a turn. Bearings however certainly would. Check for the play as suggested. But either one is possible.

 

I had left bearing go bad and it does not get worse whenbrakes are applied. I did however hear more of bad noise when I made certainturns and the load was on it more so than straight. like the others mentioned, checking for play is key in finding out if this is the problem .

 

Funny story. A noisy bearing isn't always a loose bearing either. Take it for a drive on an open street without traffic and do a slight slalom. If while turning right the noise gets louder, check the left bearings for wear. If it gets louder while turning left, check the right bearings for wear.

Edit - Watch:

 

Ive narrowed it down to it being the brakes. When coming to a slow stop, you can feel the brakes grab then slightly let go then grab again, and the squeak only makes the noise once the pads hit that certain spot on the rotor. So I'm going with my rotors are warped.

 

I would pull the pads off and check them, I am going to say I am 99 % sure this is either pads that are worn out or could be a little rust built up on the rotor. Always check the easy cheaper stuff first.
