I pulled the freshly torn UBJ boot today. BJ looks and feels fine.
I started installing the new boot when I noticed that included in the kit is a white cone shaped piece that is not in the old boot or on the BJ shaft. It fits the end of the shaft above the threads where it has a slight taper. Anybody know what and where this goes?
