vacuum block off dana 30

Okay so I forgot to take pics on this one but any ways for those of you with jeeps that want to get rid of the vacuum heres how. What you need a welder or 3/16 sheet metal a cuting tool of some sort to cut the metal. a non vacuum passenger side axle and a socket set. jack up the rig under the fron axle and place jack stands under it. Pull off the vacuum plate on the passenger side axle tube. Then decide if you want to remove the guts and weld the hole on the end shut or cut a sheet metal piece to match and drill the holes. (Inside that hole you will see a coupler. In my case i slid the coupler over the two piece axle shafts and welded it on there till i get a non-vacuum axle shaft as this was a spur of the moment. That way is not to stay just temp. I don't recomend any one do that.) At this point replace the vacuum box with your new one and then replace your 2 piece axle shaft with the one piece. Another note to be made is if you do this I would recomend getting manual hub set up in the near future as jeeps front drive shaft spins all the time.

I didn't read the whole rite up cause i'm lazy.


You know when you pull apart all that vacuum crap theres that shift fork? I'm guessing what you welded and the 2 peace axle shaft and shift fork. Anyways if you pull the short shaft out and that shift fork, flip that shift fork and put it all back together you don't have to weld anything.. Just thought id let you know, its a lot stronger since you don't have to heat the shafts weaken the metal.

i cut the fork out. like i said my idea was not recomended just what i did. also you can get a direct fit tj shaft for like $50 but i figure forget it mine is still holding up even after a wreck.
