Squeak Squeak
Have heard a squeak or squeal coming from under the truck when in motion (no brakes applied). It is not always present and changes pitch with speed. Tapping the brakes can cause the noise to go away for a while.
My assumption is that the wear sensors on the brake pads are causing this. I am replacing the pads (and rotors) this weekend. I hope this clears up the issue. On the "slim" chance (yeah right) that I am wrong, is there anything else that could be causing the squeak? Since it changes with speed, I have ruled out the suspension. Is that a valid assumption?

I think the brake wear indicators would squeak the other way around, that is to say, when you apply the brakes rather than when you're not. Anyway, I'm hoping to see what the suggestions are, since mine's doing the same thing occasionally.

The wear indicators will squeal a little all the time once the pads are worn down, then a little louder when you use the brakes. After you let up on the brakes the squeal will disappear for a little while but will return.
Because the pads are always in slight contact with the rotor all the time even when you aren't using the brakes is the reason for this behavior.

I am having the same problem with the slight squeak. I just replaced my hub assemblies a couple of months ago so I am pretty sure that they are not the cause of the noise. The brake pads looked alright also. I was thinking either u-joints in the drive shaft of the axle shafts. I haven't gotten around to narrowing in down yet. Let us know what you find out.

I'm not sure if this will help or not , but dusty conditions can cause a squeak like that. There is a plant a few miles from here that's the larget cement producer in the US. All of the parking areas are either dirt or are covered in fine cement dust. If you are like me, when I back out of a parking space, even with a manual transmission, I barely touch the brake and then shift into a forward gear and drive away. The workers at the plant's trick is that when the brakes start to squeak, they go kind of fast for a short distance in reverse and hit the brakes hard. It works every time for them. Can't hurt to try.

it's the brakes.
rinse them really good with water and then drive the truck and see how they sound. pretty sure they will quiet right down. mine do it all the time and when i wash the truck i rinse them when i wash the truck.

It could be the brakes, but I don't think that it is. I have had this squek for a while, even when it was wet. It will squeal even when it is raining and wet out. I will try washing them with water just to see though.

I took some mental notes yesterday when it squeaked:
Only happens when going forward, not in reverse;
Definitely something rotational, because it increases in frequency (not pitch; the sound doesn't change, just how often it squeaks) when speed increases;
It's not a squeal, it's a squeak;
Brakes are not grabbing or pulling;
Either it only happens after the truck has sat overnight and I've driven it to work, or I can only hear it when I'm in a concrete parking garage where it can echo;
My emergency brake isn't working very well (I have rear discs). Anyone who has read the FSM procedure for adjusting the e-brake on a truck with rear discs, does that look like a full day's worth of work to you, too? Holy cow!
Brake pads are stock. I don't think there are any zerks on the driveshaft at all; in fact, I think there are only two zerks on the whole truck although it's been about 4,000 miles since I last crawled under there with a grease gun to check.
