Clutch fork question

Thank you everyone for your feedback. I'm pretty certain I found the problem. I've been sorta avoiding the removing of the release fork because I needed to do some sawsall surgery to remove useless OEM heat shield. When I assembled the truck and landed the cab on the frame, the fork was already in place and no real good way to remove it. I cut the shield out to gain clearance and removed the fork. The pivot ball was extremely loose and most likely the problem. I really appreciate everyone's help, feedback, and suggestions.
