Sorting out a 99 Miata at the moment and I'm having trouble with a mysterious Squeal.
The sound typically starts under hard acceleration, but can happen under any amount of throttle. I have gone miles without it occurring and then it happens twice in a mile. It sounds like it is coming from somewhere in the rear end.
It seems to be directly related to speed and when I stop, it doesn't start up again until sometime later.
I have replaced:
Rear hubs and rear bearings
Driveshaft
Brake pads and rotors
Thanks in advance for any leads.
