ok so this been sitting on stands for ages so I wasn't too mad when I couldn't turn front drums. Im going to move it to another spot in yard via engine I hope but pushing isn't out of possibility not moving it far lol. Anyhow I took the 3 screws out of the drum gave drum a whack with hammer and it popped off. I slid drum back on and can spin the wheel (hub) just fine. So I put three screws back in tight and wham can't move drum ♂️ If I loosen screws so they barely touch drum then it moves so I'm worried I have some kind of problem.
