Ok, guess I got lucky. Good luck and let us know how it goes.

 

I sprayed some silicone spray near and around the rubber bushing at the bottom end. Becareful around your brakes and rotor.

 

Google search is very helpful, which led me to this thread. I also have progressive on my ultra, squeaking like the devil the past week. Will try to rotate the tops to see if it goes away... probably doubtful it will fix the problem. If not will try the suggestions above. Cant really afford to buy anything right now
