I have a 1997 E-150 Van with only 70,000 miles and the engine is a 4.6 V-8 and having problem noise from a bad bearing in a pulley I think. But don't which one. I replaced the Serpentine Belt and still have this noise. It sounds like a bad bearing. I have not used this Van very much in last few years so was parked most of time.


Thanks, Robert

Take the belt off and spin the pulleys to see which one makes a noise or is rough rolling.

I've done that to all the pulleys and still cann't find which one is making the noise. The sound seems to be coming from AC unit but not a 100 percent sure.

Bert

Run it with the belt off for a VERY short time and see if it's still there.
