I feel your pain man, I'm in the same boat as you right now. I just replaced my pads and rotors last month and I'm starting to get a vibration during braking. I took the car to my mechanic last week to have all the front suspension parts replaced (ie. control arms, tie rods, sway bar end links, ball joints) because I thought they might have something to do with the vibration and although they did reduce it its still there. While doing the work last week I get a call from him telling me my passenger side cv boot is torn to shit and grease is everywhere... great. I just replaced the drivers side 3 months ago and now I got to do it all over again.
