So I'm going to be swapping the 1 piece axle shaft in my d 30 with the disco. What all do I need to do it ? I figure the shaft but what about the carrier bearing ? Do I need the short side too?

 

No need for any bearings. All you need is the passenger side axle seal(have to pull the carrier out to put it in), and a longside shaft. Also you need to make a block off plate for where your vaccuum actuator housing sits on the axle. Just a sheet metal plate with 4 holes drilled into it and some rtv will suffice.

 

Also now that I read the post again, its worded like you are wanting to swap disco axle shafts into your current d30 with a solid 1 peice passenger side shaft. If thats the case you cant, and why would you??

 

No i have the disco and i want the 1 piece shaft you were right the first time so i need to replace the axle seal on the passneger side why ? And once that is all done with the block off plate i wont have the vacumm stuff for the 4by right ?
