A couple of months ago on a drive out to glamis sand dunes in my 02 wrx with 87k miles I started to hear a very low grinding noise and now its just getting worse.
It doesn't sound like its just coming from a single wheel as if it were a dry cv, so its getting me thinking that maybe it could be a differential or two?
Anybody have any input?
I really dont want to tear into each cv to check if one is dry or ruined and it be something else so figured I would start here.
Im starting a driving job where I have to drive my car everyday and don't need something blowing up on me.
Thanks in advance
