Ok ill try and make this as simple as i can. I believe my vacuum motor has gone out on my front axle, it does not engage and obviously wont give me 4wd. I know about posi-lok but dont have the cash to spare right now.
so my question is, Can i engage the axle and leave it without harming it and if i do that will i constantly be in 4wd or only when i shift to 4wd?
You can use washers to space the collar over and have the two sections joined inside the axle tube all the time without any issues. You can also swap in a shaft from a TJ Or late model xj along with a seal inside the diff and be done with the disco as well.

heres a link for the DIY posi-lok, i just did mine all together it cost a little over 50 bucks and its a excellent setup. if u do end up going this route look through the whole thread its got some great ideas on how to improve the first method.
