If you have a Spline lock installed they can be nearly impossible to get out without a proper puller. We designed these just for removing the hubs. When removed yours have your cut splines in the crank, on reassembly simply line the splines back up, and follow factory TQ, and stretch procedures on the new bolt.
We offer them for the S55, and the N54. Choose which option you need.
