Eliminate Dana 30 Vac Disconnect

[Chop]

i have a vac disco D30 and i want to know if i can put a tj pass side long shaft. inplace of that fag ass vac disco 2 axle shaft style. im just looking to keep it going so i can wheel till winter

[Cooter]

Yes you can.

You will need to add a seal to the passenger side of the D30, however.



I did this years ago by modifying the housing to accept a driver's side seal, but I know there is a part number that will work without modifications.

rock on. yeah i dont want to put any more work than i have to in this front axle. where do i install the seal behind the carrier bearing like a tj or at the end my the vac disco?

Just like a TJ.

Here is a writeup for one of our Club members who did the swap in a YJ

Lol... you just want credit cooter I have a part # for a seal that will work without grinding the housing. But the grinding is the better way for it is a better seal.

what is the part number for the seal with out grinding. i found a axle shaft out of a tj and i was hoping that a TJ seal would work?

[Chop]

so far i have got the part number of the seal which is a national seal pt#40576s (thank you killer B) im just waiting untill tomarrow morning for it to come in. and i have a passenger side axle shaft out of a 98ish TJ.

here are some pics
old axles:


drivers side seal stays the same


Add and passenger side seal if you want to grind the housing and put the correct seal in the PT# you need is a timkin 710068 or the same and a TJ axle shaft seal

if you dont want to grind the housing like me you can use this part# national seal PT#40576s harder to find these seals came in older jeeps with axles like the dana 27 and a few others. but you will not need to grind the housing
if you go this route i stacked 2 seals together to make a better seal. but i did need to grind the outer seal metal surface to make it easyier to fit in the housing.


here is the vac disco housing. i would take the old bearing out of here to make a little more room for the new shaft. as for the seal im going to leave that because i really dont care.


more pics to come when i get the seal
