08-20 Sportster, 08-17 Dyna
Late model Dyna and Sportsters are now using hollow axles. The use of this new hollow axle has eliminated the center point of the axle, which had been preferably used as a center point for rear tire alignment references. Lube the o-ring ends of these tools and insert in left and right ends of axle on Dyna, and Sportster models. This will give you the correct center point required for safe vehicle alignment.
