'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?

I would bet it's the bearing. Heats up, it gets looser. Brake and lateral
motion put sideways pressure on it removing play. No grease fitting - time
to replace the bearing.

Makes sense. Thx Ken. Is bearing replacement a DYI job? I'm fairly
mechanical ( I've replaced rotors on several cars and replaced an
entire air suspension system with coilovers on a Lexus LS400

I think you need a bearing press. Not exactly a tool most of us have lying
about. I was lucky to have the dealer replace mine under warranty (years
ago).
