So, the real question is ... how badly can I screw this one up!

Back on topic - I see you made a case for changing it. Do I understand correctly the intention is to prevent the rail guides from failing?

Are the rail guides plastic? Why would they fail if the chain tension is off? Is it because the chain slaps against the rail guides?

Is 'that' what makes the noise you said is no longer being made?

Why would simply changing the spring change noise otherwise?
