tranny grinds_have a welded_help
 

Last month I put in a new stage 1 ACT clutch because the old one was slipping. I also changed out the throwout bearing but I could not get the pilot bearing out so i left the stock one in.

The clutch was fine for a couple hundred miles (ACT reccomends breaking in period of 300 miles, I thought if it drive easy for the last 100 it would be okay with a welded). I put in a welded diff and it was okay at first. then it started making noise when i would change gears into second and a little noise in third.

While idling, if i press the gas and move the clutch pedal in and out simultaneously it grinds as well....

Any thoughts?

thorw out bearing or pilot bearing. My money is the pilot bearing is bad.
