Baffled by annoying Squeaking Sound

[xdarkxfirex]

I've had this since last year. I first thought it was the sway bar bushings, or suspension, but they are all fine. I changed two motor mounts that were bad and though they might be the problem, and I'm still getting this issue.

It happens when you put the car in D or shift into R. The transmission shifts fine. I replaced the transmission fluid with full synthetic WS compatible last spring at 50k. The sound usually stays there and comes back and goes. Sometimes you hear it over bumps or when you accelerate
