Rattling noise that stops when you push in clutch also cluch peddle has been hard to push in since clutch replaced a year ago

Sounds like a release bearing is going bad.

cluch plate to be replaced, flaw in materail caused plate to shatter!

replace the clutch master cylinder. The rubbers on the piston swell over time and/ or break down blocking up the ports in the cylinder.. Wrong fluid is the main culprit for this type of fault.

Possibly a broken ceramic brick inside the catalytic converter.

if the noise is only there when you push down the clutch, you need to replace the throw out bearing.

It's either leaking out of the line from the M/C to the slave or it's leaking out of the slave

those trucks had problems with the fire wall breaking .have some one push the clutch pedle and watch the fire wall from under the hood were the clutch master cylinder bolts too if the fire wall moves u need to buy the repaire kit from ford.

take back to dealer and have them check the neutral safety switch on the clutch because if the switch is not adjusted properly you will have this problem

you can check cluch fluid and make sure that its full also your cluch could be starting to go out

chances are the adjustment of the throwout bearing fork is the problem . because of vibration that is the rattling that you are hearing. correct adjustment should be as follows.

#1...peddle travle should be no more than 1 1/2 inches

#2...the clearance between throw out bearing and fork no more than 1/2 inch

#3...clearance between fork and fork stops is 1/8 inch

also there should be grease zerts in the shaft that holds the fork and linkage make sure they are not dry of grease...please rate the solution....thanks
