The Astro Tool 78834 "Last Chance" Impact Rated Hub Removal Bolt Kit is designed for press-in, bolt-in or otherwise corroded hubs that should have come out with other attempts and other tools but just refuses to! Simply use the impact rated ¾” (19mm) socket size M12 and M14 thread bolts and 15/16” (24mm) nuts in this kit to push against the knuckle assembly and force the hub out. Use the free hole locations existing in the hub or hammer out 1-2 wheel studs to install these press bolts. These custom press bolts in this tool feature a ball bearing end and work with the included press feet to freely angle against uneven knuckles and dust shields. Kit includes 2 M14 press bolts and nuts, 2 M12 press bolts and nuts, and two press feet.
