belts? whats wrong with you guys its obviously a muffler bearing going out and squealing.
So I was coming back from a date with my wife and I hit the gas to pass one of the many turtle speed drivers here in Guam and a loud SCREECH was heard coming from what seemed to be my front end area. What in the world could that be? I was able to reproduce it two more times then I got a little worried I was doing some serious damage. It was only when the tranny shifted out of D to 2nd and only for a few seconds then it was gone. Any thoughts?
Turn up the stereo, it will go away
Unless you're listening to some screechy music![]()
My belts squealed on start-up also. Are yours doing this?
Just to add another idea, my truck "whistles" under acceleration. I believe this is caused by a vacuum leak somewhere. Mine is very subtle, but it is conceivable that a more severe intake or vacuum leak could create the sound you are hearing. Maybe not, but replace/adjust your belts and see what happens.
fwiw
OMG, an 80 whistling under acceleration.We may need a whole new thread for that one.

What Rob meant to say is that the (fzj) 80 factory exhaust system whistles under acceleration normally. Some trucks more than others.
