Starting work on the Dana 30 with 4.10s I got from a local guy. I am starting the refresh and trying to figure out what I will keep from my 3.07. I know I'm going to swap over the brakes and steering parts. There is a lot of rust on the hubs and knuckles, what should I be looking for in terms of whether I should just clean and paint or swap out from the D30 currently under the 95?
There is a hole on the yoke side of the diff that is open--fluid dripped out when I moved it. My guess is some water got in there because when I drained the fluid some was thicker and blacker and some was thinner and more green. What's going on there?
Also--how quickly do I need to get fluid back in there? It is still pretty coated, but I don't want any corrosion in there.
Anything else I should be thinking about? I don't think any of the seals are leaking but is that the sort of thing I should be doing while it is on the bench?
Obviously, this is a new adventure for me so I appreciate all of your help. I'm getting the wire wheel going now!
So, I'm in the midst of doing the same thing. And, while it may be overkill, I'm replacing a lot since it's sitting on jackstands. I'm replacing the ball joints, tie rod ends, u-joints, and hubs. Mine also looks pretty crusty since it looks like it sat in the guy's yard for a while. So, while I have it torn apart, I'm soaking the knuckles and the ends of the axle in Evapo-rust. Just to get it all cleaned up and then painted.
Like I said, probably overkill but that's just me.
Want to share what brands you bought? I'm thinking it would be a cool thing to do the front end but don't know anything about what to buy. Up for suggestions.
My understanding is that requires pulling the whole insides of the diff out and then re-shimming when you reinstall. Not disagreeing but for me, that's beyond my comfort level. If I did that though, I would also replace the inner bearings.
OP, keep in mind not everything on the D30 is the same through the years of the YJ. It's not a major issue just know some things are different, if you search around here you'll find a thread from Mean_Max about some of the differences.
Thanks for this. I'll look around for the fitting.
Also--as the scope of the job grows and it takes longer, I'm guessing I should throw some oil back in the diff to keep it from corroding. Is that right? There's a coating on the gears (I haven't hit it with brake cleaner or anything) but to be safe do I need to fill it? If I need to fill, can I just use cheapo motor oil knowing I'll drain it later?
Both D30s are from 95s--I thought the only difference would be gears. I'll look into Mean Max's stuff. I've learned a lot from his posts before...
Since the breather is already missing out of your diff a great way to keep it from happening again is tap it and put a brass nipple on it to connect your breather hose too. If I recall correctly I tapped mine 1/8NPT. You will never have to worry about the breather falling out again.
