Is the splined section of the clutch boss on a 2000 pressed in? Mine is loose in the bore. At least I know what the cause of my squeeling clutch is.... the insert spinning in the bore until the clutch fully engages. I cant figure out how this section worked its way loose. I put in a billet basket last summer, but torqued the nut properly. I'd like to know so I can avoid this problem in the future. Anyone else had this problem and figured the route cause of it?
