I just researched how a clutch actually works for the first time, today. Was one of those things that you used and just knew it worked, but never really wondered how, like a toilet or or one of those magic mats in front of the grocery store door that makes the door open automatically when you step on it.

So, the failed clutch arm bushing makes sense to me regarding the shudder/judder.

I'm actually looking forward to doing this clutch job.

I really appreciate all the advice and insight.
