There is a knock coming from the right front side wheel well. It comes and goes at random. But sounds when hitting bumps. The rotor is warpped.. (working on getting new one.) But still cant find the knocking sound. Dealer cant do anything to "duplicate" the sound. As soon as any pressure is applied to the brakes no sounds is made. I am at a loss of the possibilities.... The sound is getting worse.

 

Try taking a speed bump a little hot...if you can replicate the sound its suspension related...

I would start with the sway...brackets...and bolts...

Then move to the springs...etc...

 

some have said that the sway bars need to be lubed and the noise go's away.the only time most have heard it was going over speed bumps.
