It's not hard...it is a little time consuming. You'll need to pull the axle shafts, drop the carrier, replace the inner seals and put it all back together again. Dropping the carrier is not as bad as it seems. Everything just needs to go back together exactly as it came out. So make sure to mark the bearing caps before you take them off.

Seems like Carl (swamp boy) used something similar a few years ago. Maybe send him a PM to see how they worked out. Wink

Those are not to keep the oil in...but rather keep dirt and debris out. They are replacements for the inadequate plastic dust shields from the factory.

I have them on my Unlimited as well as most of the guys I wheel with. They do a great job keeping dirt out if you grease them appropriately.

So what do i need to buy to replace all this crap? Can i get it from a napa, or is this gonna come straight out of the stealership? Is it a generic part or specific to the D30?

You should be able to get the inner seals at most auto parts stores. Aside from hand tools (including a good torque wrench), the only other things I would have on hand would be a Factory Service Manual and a punch to mark the bearing caps.

As ehirner said, that link is to an aftermarket seal to keep debris out of the tube. I run them on mine and they work great. Since you have to pull the axle shafts to get to the inner seals anyway, you might want to consider them. Especially considering what you did last year....

I just replaced both seals and installed the Red axle tube seals as well. It was pretty straight forward as Phantum said. I purchased a length of threaded rod and some thick washers of appropriate size from Lowe's to assist in the removal/intallation. I would suggest is IF you have to order the seals (about $5 each is to order an extra set or two ( I messed up a couple trying to get them to seat just right) Keep any leftovers as spare parts.

So far every thing works great!

I took the disassembled opportunity to also replace hub/bearing assemblies (sometimes called unibearings I think?) as well (another $100 per side) as one was pretty shabby looking and they came with all new wheel studs already pressed into place (I had a couple that were iffy)

Article I found particuliarly helpful was:

http://www.madxj.com/MADXJ/technical/technicalfiles/ARD30shafts297andSeals/D30shafts297andSeals.htm

I do not have the vacuum disconnect axle (thank goodness! They look like even more of a pain?) so I just ignored thast part, the rest is same. BOTH sides of mine use exactly same seal.

Also while im thinking about it is there a safe way to permanently connect my inner and outer shafts on the disconnect side while I'm taking this thing apart?

Sadly i do not have time to get the Red seals as someone has olunteered to to help me with this tomorrow, and we don't hae an FSM. But we do have a few Appalachains (sp?) which should be almost god enough Very Happy

Sadly I do not know anything about the Vacuum Disconnect setup.

You are looking to do away with it and go to a one piece axle on that side?

I haven't ever heard of that but then again, I'm sure someone has done it either out of necessity or just to see if it could be done? . . . .

I'm not sure I understand why you'd want to disconnect it via vacuum either?

gas mileage wear and tear. However i'd rather have a more reliable setup and get that vacuum line out from under the jeep and cap the lines. I've seen people take apart the vacuum motor and stack washers on the arm to force it closed. That seems kind of Ghetto, any other solutions?

Any input here?? I'm pretty sure i bent the axle now, think it was from hitting a tree while wheeling. What are my options here? Is there a 1 piece axle solution (ditch the cisconnect??) what woudl i need for that? what other vehicles could i pull the shaft from besides a 94 wrangler? Am i better off just finding another axle?

I did this conversion on a HP30 I pulled from an XJ that I swapped into my TJ.

You can use any one piece shaft from XJs or TJs. All TJs will have the larger 297 or 760 u-joints compared to the 260s on almost all YJs and a lot of XJs. If you can locate TJ shafts, get both and upgrade the driver's side to the larger joint also.

You will need a different inner axle seal placed just outside the passenger side carrier bearing in the axle tube. IIRC, it is NAPA #CR11880 or something like that. Then cut a block-off cover for where the disconnect mechanism bolted to the housing. Use some RTV and seal it up.
