I have recently realized there is play in the bearings. Bearing moves slightly inside the pulley. That scares me as I have heard horror stories of pulleys grenadine and breaking apart after experiencing play in the bearing causing a lot of damage.
I do have a scattershield so that should help at least somewhat but if it comes apart at the snout that would be bad news.

I am now wondering if I need to replace the bearing and take my chance with the aluminum pulley or if I need to just replace the pulley all together.
Are there any 65mm pulleys that people had better experience with? I know the polish company had pretty decent reviews but I don't know if they are still around selling their steel pulley.

My other question would be, if I reach it with another 65mm pulley, will I need a re-tuned from Eurocharged or should that not be necessary? If I wouldn't need a re-tuned, does it make a difference if tune was for 64.7MM and new pulley is 65MM?

Amy advice is appreciated!
