I have a 89 Si. Just had the motor swaped. Sometimes when I drive theres a really loud high pitch squealing sound comming from I think under the hood. If i touch the brake or give it gas it stops. When i slow down to a roll the squeak slows to my speed. It dosent sound like brakes i was thinking something with the axles. It does it off and on sometime it sound good sometime not.

 

Its not 92-00 sorry wasnt looking...

 

like a belt squeel?

 

not a belt cuz the sound slows down if the car slows.

 

new brake pads...

 

It wasnt making the noise before the engine swap. I need to have a look!
