I have been hearing a heavy "metal" type of clicking when I slow down on the left front wheel area, when the wheel is in a "slow" rotation. The clicking noise is only noticeable in a slow rotation and the number of clicks slow as well. Any adivse? Thanks!

I just installed new front brakes and rotors and the noise is still there.

You may have a loose //hanging wheel speed sensor or the brake pad is low enough to catch the metal sensor on the rotor, causing the noise, nevertheless, that wheel will have to come off to be able to inspect the area so we can determine exactly what it is, Im sure it nothing to be alarmed about

On a 1999 chevy Sub. Isn't the wheel speed sensor part of the "hub assembly" which is all one part? So how can this be loose or hanging? Also, as I stated, I just had new front brake pads and rotors replaced last week. I wish you comments were more helpful. Still looking for an answer.

Thanks so much for reaching back! Yes, with OEM parts

Yes, it is more than likely that the cv/ujoints have become pitted and are creating the noise you are describing, the only other possibility is the lockup mechanism inside the hub. And yes the wheel speed sensor is part of the hub.

This is either 2wd or a k1500. The c1500 is 2wd.

Not to nit-pick, but a 4wd you can get it up in the air and put it in drive to listen while the truck is stationary.
Have you tried spinning the wheel by hand when it is jacked up to see if it will make the noise? Any play in the wheel?

IF you have access to chassis ears, you may be able to narrow this down much quicker. Otherwise have someone outside the truck listen as you pass to see if this is somthing that can get narrowed down further regarding location.

Does this happen only when braking? IF you are slowing down and take your foot off the brake, is it still present?

If only when braking, can the pad move in the bracket or is it tight?
