Working on the big hubs of a newer GM heavy-duty truck? You’ll need this special socket. The Lisle 31510 is a 9-pin socket made specifically to remove and install the large, circular hub nut found on the full-floating rear axles of 2020 and newer Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 trucks with dual rear wheels (DRW) and the 11.5-inch or 12-inch axle hubs. It might also fit other vehicles that have a similar 2.97-inch outer diameter axle nut. This isn’t a standard socket – it has nine pins that engage with the holes in the special locknut. The socket is made from hardened steel with a durable black oxide finish to withstand the high torque needed for this job. It has a 1/2-inch drive, so you’ll use it with a strong breaker bar or torque wrench. If you’re doing brake work, bearing service, or any repair that requires pulling the rear hub on these trucks, this is an essential, professional-grade tool to have in your box. It makes the job safe and correct. Always verify your specific truck year and axle setup before purchasing.
