Check:
Thrust bearings installed backwards---CHECK - They are fine.
Loose bolt in head---CHECK - I thought that was it once.
Check Head Block Condition---????? How can I tell?
Lube & chk. rubber dampners---CHECK New ones AND they are lubed
Bearings In Blade Grips---CHECK One bad thrust bearing - missing a BB.
Swashplate wear---CHECK No wear
I have have a bad thrust bearing for sure. I just wanted to see if maybe it was something else. The other bearings in my head are A-OK.
