Here is all you’ll need to handle the two different-size spanner nuts you’ll find when servicing the NV4500. As usual, we have not compromised a thing; you can tell the first time you pick it up! Weighing in at about 24oz, our heavy-duty dual spanner wrench arrives ready and able. Design includes a provision for a ½” drive breaker-bar for removal and a torque wrench to install.
We then devised a unique socket for GM’s 4X4 app:
Many use a vibration dampener that will not allow the wrench to access the nut. With the torque specs this high it absolutely must be burly to stand up to repeated use. The 4-notch design spreads out the load while maintaining stability. Milled from super tough steel, this will be in your tool box for many years!
