Hi I have a 2006 Dakota 2 wheel drive. I am getting a noise out of the back that sounds like a clicking noise or rocks in the hubcap when braking. I only hear it when applying the brakes, when coasting or even trying the emergency brake I do not hear it. I also do not feel anything in the peddle.This strted a few weeks after I had the brakes done, had rotors drums and the springes replaced.. Took it back to the mechanic said the brakes are fine but the noise is coming from the rear diff. To me it still sounds like the brakes. Any ideas?
