Default Chirping noise from the rear

99 cab 65k.
I have a chirping/whistling noise after car is warmed up and moving over 35 mph. I hear it while coasting or cruising. Sound goes away when I apply any type of power. Does not go away when I apply the brakes. I have brake pad sensors installed. Is this a bearing?

It has been extra cold here in the DC area. It takes a few miles for the noise to start. I can't really hear it below 30 to 35 mph. Sometimes it stops briefly when I turn to the right to swith lanes etc.

Engine/trans mount deflated/damaged, allowing droop that causes slight metal to metal contact when the rubber warms up enough to flex more?
Does it sync with tire or engine RPM?

When coasting over 30 mph I get the chirping. When I apply gas it goes away. When I let off the gas it comes back. If I turn to the right it briefly stops. Does not seem to be syncing with engine RPM. Is there an easy way to tell if the engine/tranmission mounts are bad?

One way is to look at the tail pipes. Sometimes a bad mount will allow one side to droop enough to see the difference. (about 1/2")
Also you could jack up the engine to see if moves alot before the car starts to lift.

Loose spark plug? Very common in these cars. BTDT Chirping noise I cound not identify where it was coming from.

Plug literally came out with my finger tips.

I had a very similar issue with a Boxster and it was a brake problem. Removed pads and replaced. Very annoying to track down.
