I had a clicking start on my car on saturday night and within about 2 hours of driving stime or so it turned into a major thud at what seemed like every rotation of the wheel or so, it seemed to be primarily coming from the drivers side. Today I got the chance to jack one side of my car up at a time, I turned the wheels and each side rolled freely while the other side was still on the ground. I got under the car and looked and the shafts were turning fine all the way up to the transmission. That isn't normal is it? Neither made any noise when i was rolling them and gave no effort at all to turning them. I put it in first gear and it did the same thing, I turned the car on and put it in park, I turned the car, but not the engine on and put it in first. Nothing changed the results that I got. What do you think the problem is? please throw some theories out there and ask more questions and i'll try to answer the best i can.
