Wheel bearing/hub replacement

[Runaround]

Can someone tell me size of the axle nut on a 2018 2500 4x4 and the torque specs for it and the four bolts? Also do I need to a puller to press the axle out of the hub?

My sil and I just did the front hubs on his 2008 Dodge Nitro. His axle nut needed a 32mm socket and really needed the puller to get the axle out of the hub. Getting the hub off was a major job!
He rented the puller and slide hammer from Autozone. We used a ton of penetrating oil and had to resort to an air chisel to finally break the hub loose. The Nitro did live in the NE for many years so it was well seized.
Good luck.
