Replying to: jpw454 (Oct 27, 2008 2:20 pm) It is pretty subjective as to how loud your "roar" is, that said, generally, if replacing the pinion bearing does not correct the problem, then it is the typical gearset noise you are hearing. Generally most noticeable above 60 MPH. My guess would be a new ring and pinion, aftermarket, not OEM. No guarantee though, one guys opinion. HTH
