How does one know if it's working or not? When it's gone does it make noise, vibrate or are there other tell tail signs? What do you notice with a new one installed on a car with 100K?

Mine has 114,000 miles on it, I changed the clutch at 90K and it seemed fine. I drive the car pretty hard and run a few autocrosses a year. Maybe its shot and I just don't know, its not ratteling and still grabs though. Whats the go to aftermarket option for these things?

Test it:

My old one was not making noise and looked ok on the surface but failed the elasticity test. Rather than drop $800 for a shiny new one I found a low mileage takeoff that was within spec for $150.
