So I have that airplane propeller sound that started 2 weeks ago. Pitch changes as I swerve left to right, with emphasis on a right swerve! I don't know if I could do this myself.....checking around, best shop deal(owner operator type of place) gave me a quote of $450 for both front hubs, 5 year warranty, or, knock $100 of the total with cheaper Chinese hubs with a year warranty. Deal? Other shops were somewhat higher priced.
