High pitch whinner ('90)
'90 Miata 106k miles.
My car has developed a very high pitched whine/whistle coming from the drivers rear wheel. Seems to take 15-20 minutes for the whine to begin. Can eliminate temporarily by pulling up emergency brake or swerving car f/ side to side. Brakes? Bearing? If bearing, is there a grease fitting? Chip L |

Heats up, it gets looser. Brake and lateral motion put sideways pressure on it removing play. No grease fitting - time to replace the bearing. -- Ken Lyons '97 Brilliant Black/'90 Classic Red Inside the Beltway |

I'm fairly mechanical ( I've replaced rotors on several cars and replaced an entire air suspension system with coilovers on a Lexus LS400 Chip L |
