Throwout bearing slipped off clutch fork

Look for a cracked or broken fork clip the clip that holds the fork to the bellhousing, also check for excessive wear on the front bearing cover that the throw out bearing slides back and forth on. Also broken or damaged clutch fingers can cause side loading. I had that problem for years trust me I had to Burns on my hands to prove it. It can be very frustrating as I'm sure you know. That system will work pretty good but all components must be in good working order. Also even the rubber fork boot should be in good working condition.
