Bought a new rear axle for my 2002 Suburban which required 6 bolts per axle hub (12 bolts total). An ABN truck wheel stud installer was used, which provided more clearance around the stud than an automotive tool. I clamped the axle in a vise, put the bolt in the hole, and using a setting tool, then pulled the bolt into the hole with an impact wrench. Patience is key as it takes some effort to get these cleats to snap into place flush. The instruments got very hot so I looped the setup with cycles of on and off to allow the instruments to cool down a bit. Hassle free installation. All cleats are flush, no cleats.
