    Does anyone know what size socket I will need to take the nut off of the gearbox so I can remove my pitman arm? It is a 2003 Yukon XL 1500 4x4. I don't want to start the job and not have a large enough socket. I think that [MENTION=48417]Coach24[/MENTION] just did one, maybe a few of you remeber what size it is. Thank you.

    Been a looooooooong time since I did one. I thought it was a 23 mm or something like that. Can't say for 100%

    1-5/16". Use a impact socket, and use it with the Pittman Arm puller on your air wrench.
