so the titles says it my question is, one does my 93 have a vacuum disco? two if it does have a vac disco is there anything special i need to do with it? i read somewhere that there is a needle bearing somewhere on there that i need to be careful about, but when i pulled the old shafts the other week i didnt see any kind of needle bearing, also is there just the inner seals or are there outer ones too?

'93 dana 30? unless it was swapped previously you should have no vacuum disco and only inner seals.There are though oil slingers on the ujoint ends...

claygrassmann

by oil slingers you mean those lil hard plastic rings around the shafts on the u joint ends? and yeah its a d30 and pretty sure the original cause them hubs were on there good thought they were welded on for a bit lol

fantic238

yeah, kinda more like a hard plastic disk

claygrassmann

are those really necessary? i didnt see much use for them other than they help keep junk out of the tubes

fantic238

that's a good use...you don't wanna screw your inner seals before the time don't you?

claygrassmann

lol its def a good reason, dont really wanna do inner seals anytime soon atleast not till i get a locker and ill have the carrier out anyways, just think its funny how its called an oil slinger when i dont really know what oil it slings lol

fantic238

I don't know, the parts catalog says oil slinger...
