David Brown Posted February 13, 2009 Report Share Posted February 13, 2009 I am new to this, so here goes. I have upgraded from a 1995 STS that my son now drives to a 2001 STS. I have a vibration in the front end around 70 MPH. I have replaced the two wheel bearings that made the noise almost go away. When replacing the left side bearing I saw grease coming from the CVC boot, checked it for holes found none. It looks like its leaking around the side closest to the trany. It fell like there was a lot of play in it. Do I have to change both CV Half Shaft Assemblies at the time, and how hard is it to do. Link to comment Share on other sites More sharing options...
