Just last week I started to hear what sounded like a belt chirping.
This noise occurs when in park and driving down the road.
Around 50 mph its hard to hear.
My mechanic said it's not my belt and sounds like its coming from the bell housing.
The local transmission shop agreed with the location of the sound.
The shop said it thinks its a bearing about ready to go.
He's going to tear into it tomorrow.
Any ideas?
I changed the fluid at 30,000 and 60,000,
It just hit 90,000
2003 Tarus
The car was running fine and purred like a kitten.

I'm guessing the CPS (Cam position sensor). It makes an RPM based "chirp" when it starts to fail. Replace it soon, as it drives the oil pump.

Thanks
That was my guess, also.

Talking about the CPS, where is it? And is there a way to tell how good it is?

The camshaft sensor is not the cause of the noise, it's the camshaft synchronizer. The cam sensor mounts to the top of the synchronizer and does not move. You'll need to replace the synchronizer A.S.A.P. It also drives the oil pump, so if you leave it too long, you can risk severe damage to the engine. The synchronizer replaces the distributor that was in the engines prior to '96.
