Are they quiet at 100% though? Mine are acceptable at lower power, but irritating at full.

They are aligned correctly, using the correct spacer setting, etc.

When you say your pins were bent, is this inside of the unit?

I've bought new bearings to try. I just need to get my hands on a bearing puller.
