I have replaced them myself a few hours ago. I noticed it but I thought it was a loose headset or loose spokes. I never assumed it would be the pivot bushings. If you stand your bike on the back wheel and lift the handle bars you would feel the play straight away. I took some photographs of the replacing. I will post them in the forum
i thought my headset was coming loose last ride out i had, wonder if the same has happened to me? did it make a particular sound ?
