I got my Vx back today, they could onjly determine the noise was coming from the diff. they told me to take it to the dealership and if it was their install that f***ed it up then they would reimburse me for the work. when they gave me the old half shaft back from the original install it was in pieces. is that normal for the install to have to strip all the guts from the inner cv on the halfshaft? any ideas what could have happened?
