Vehicle shimmy from right front when brakes are apply, There was a small shimmy at first, I felt a small vibration on the steering wheel when I apply on the brakes, So I took it in for an inspection, I was also getting ready for a long trip to Phoenix, Arizona and need it fix, I was told, I would need tires and alignment, this seem to get rid of the vibration, for about five hundred miles, going down hills it started vibrating again, when I got to Phoenix, I took it in and there I was told that my rotors where warped, so I had my rotors replaced, and while at it had the brakes replaced, this seem to get rid of the vibration until I got to the hills again, vibration came back worse, so I figure I better take a look at it, when I get back home, I havent done any mechanical work in about five years, due to my arm and back surgery and blurry vision, What I found was looseness on the right front driveaxle, going into the transmission, so something inside the transmission is loose or worn, I know, why could they find this and save me lot of money, I was a mechanic for twenty-eight years, twenty years of it was in the military, tomorrow im going to show the dealer and see if it's covered under the warranty
