My 4wd does not engage on the yj i just recently purchased, due to the actuator, surprised????? Any how i have been researching about the one piece axle swap to elimante the 2pc axle with the collar and fork. I have never pulled a axle before but im sure i can do it i just have a few questions. What tools will i need at the yard? Is the axle held in buy a c clip and what do you guys use to remove the clip? I have a local pull it yard close by loaded with xj s and very intrested in doin the swap and being done with it for the long run. If there is any thing else im missing please inform me it will be much appreciated. Also i will only need the passenger axle correct?
