My rearend sounds like I have birds under it. Every little bump I hear the squeaking noise and its driving me up da wall. I was under the car yesterday and check everything to see if I had an loose bolts and nothing. Then I started tappin/hitting the rear wheels with my hand and it started making the squeking noise, how can I fix that? What can cause that noise? weak axles? I need a quick fix. Any ideas are appreciated
