Wierd noise.

Sorry...Just read that and busted out laughing,I had to say it.
But seriously,I have had my differential start up a small howl in my old 98' TA and it would do it when making a turn at slow speeds.Kinda like when you are getting into a tight parking spot or driving through a drive through...
I changed out the differential fluid and additive and everything ran quiet as new after that...
Good luck man...
