Our '98 GT the other day made a high pitched noise that varied w/RPM all the way to & from Holly Pond... I figured it to be a bad belt, idler pulley or maybe an accessory bearing... Sat. I raised the hood & started...no noise. Drove a little way & the noise only happens when the clutch is depressed & the further it is pushed the louder it gets but made no noticeable noise with my foot off the pedal... Reading on the Internet they say a constant noise like I 1st experienced is a pilot bearing & noise only with pressure on the pedal is throwout bearing... Any clarifying ideas?
