I am getting a squeaking sound when I drive.
It sounds like it is coming from the front of the engine (I think).

It sounded like it was the cam belt tensioner so I replaced it but its still there.
Then I replaced the fan clutch, still there.
Checked the front wheel bearings and tightened them, still there.
Checked the front brakes, still there.

If I am driving along and the noise starts and I sink the clutch, the noise goes away.
The noise is not continuous.
I am also feeling a slight vibration when I get up around 40 mph, it feels like the engine is vibrating.

Could this possibly be the clutch bearing squeaking?
And could a bad clutch bearing cause the clutch assembly to vibrate?

Otherwise the engine is running perfect and the clutch feels as normal.
