Doc's Hubs Warranty:
Hubs come with a 3-year or 50,000-mile warranty, provided they are installed correctly and the vehicle uses original equipment (OE) wheels and tires. Please note that using offset or oversized tires can lead to accelerated wear of the hubs, voiding the warranty. Additionally, an impact wrench should not be used; a torque wrench must be used AND must meet the required torque specifications for your vehicle, or the warranty will also be voided.
