Throwout Bearing Blues
 

Hey guys i have been having a problem with the throwout bearing on my 89 Mustang 5.0. Every time I install a new bearing, it is quiet for a few hours and then starts making a squealing noise. This noise occurs when the car is in gear, or in neutral, and the clutch is released. The second I put a little bit of pressure on the clutch, the noise stops. I have replaced the bearing four times, and i have replaced every other part in there. I have a new pilot bearing, new: flywheel, clutch, pressure plate, fork, pivot, 4 throwout bearings, and i even put in a new rebuilt transmittion in yesterday. The noise persists. And today i noticed that it is making a rattling noise too. I am so frustrated over this problem. If any of you guys have had this problem before, or know what could be causing this problem, i would really appreciate your help. Thanks.

Did you grease the bearing and is the bearing retainer shaft (whatever it's called, the tubular surface the bearing rides on) in good condition? Maybe see if you can get a different brand bearing somewhere else????

Is the clutch adjusted properly? If it is always partially dis-engaged the bearing will wear pre-maturely.
