81 Hunter 30. Main halliard sheave at truck spins but not when under any pressure.. I suspect bushings or bearings are done. Anybody have experience in fixing this? Is it possible without dropping the stick?

You can buy some time by greasing the bushing but eventually the sheave and bushing will need to be replaced. I had a friend use a mast stepping crane to hoist himself high enough to service his mast head. In most cases this would require dropping the mast but not all. Depends on how the mast head is configured and how much access you have to the sheaves
