I am new to the 6x6 so please ignore my ignorance. My right center wheel sprocket has stripped all its teeth and I am not sure how to remove the center axle to fix it. Also not sure which sprocket I need to order. Its the center main drive sprocket.

Ive watched one of yalls videos on how to change the front axle but everything is so tight on the center axle. Any advice is much appreciated. Thanks!
