I started hearing a noise when going over speed bumps in the neighborhood, like an extra thud or a continual thump noise. Just hit the hundred thousand mile mark and thought that could be part of it. Today I notice that either way I turn the wheel hard I hear a popping after the turn goes so far. Are the two of the same or two different problems? Are there any other problems that start happening after that 100,000 mark? Thanks in advance!!!
