94 hb clutch fork vibrating causing slave to get air? LUK

[nissan3227]

Can uneven pressure plate fingers cause the slave cylinder push rod to shake so much that you're introducing air into the system?

I have to bleed the clutch every 3-4 days I can't find any leaks and the reservoir is always full..

Its a LUK clutch n throwout bearing... The clutch fork shakes at all rpms...

Arm chair guess ? Possibly the slave cylinder is bad. After bleeding does the clutch work properly? Try replacing the slave cylinder. If the clutch assembly is bad you're going to end up replacing the slave cylinder regardless. Try having someone press the clutch pedal and look to see if the clutch fork is moving freely. Given the size of the master clutch assembly doubtful it's leaking. How does the truck Shift?
