Nitro axle sleeves installed

So Friday was eventful, I was able to get part of the "goods" installed.

The first part of the adventure was fabricating a tool to aid driving in the Nitro axle sleeves. This was loosely based off another forum so I won't take full credit. A piece of 2" pipe and some 1/4" thick plate on one side (BFH side) welded together. A 1/4" plate with a 1/2" diameter 2-1/2" long bolt through it was welded to the otherside (sleeve end). The 2.47" sized seal driver was then slid over the bolt and a few washers were used to help keep it in the sleeve and centered between blows.

After removing the brake assembly and carefully pulling the axle out inspecting the tube reveled a relatively clean tube.

After a small wire brush ,a scotchbrite pad and some WD-40. Shiny, shiny.

Now after sitting in the freezer for 3 days the Nitro sleeve -0* in front of the weapons of choice. Axle tube was warmed with a torch to expand the metal.

Ok , so after days of gut wrenching ,bile churning anticipation of how this was going to play out. The long side tube went in effortlessly. Just a couple of love taps to seat it flush.

Onto the drivers side.
Same as the passenger side only shorter. This should be even easier right?

Axle tube is cleaned up and awaiting it's delivery.

Here's a shot of what a tube looks like sitting in the axle.

I should maybe start working on getting it all the way in. ( That's what she said ) Hey, remember that tool I made? Well it was put to the test ,because I had to pound the @#%* out of it to get it in flush. The nightmares and horror stories are coming true at this point. BUT perseverance prevails, and so does the perspiration Sorry no picture of the after but as you can guess it looks like the otherside.
Note to self ... have someone else take pictures during time sensitive tasks.

After getting both of these in I ran some tack welds around them for piece of mind. I doubt they would have ever walked in the axle, but it was cheap insurance. Reassembled with care as to not damage the inner axle seal and plenty on anti-seize on the bolts and knuckle / hub contact point.

Done deal ,time for a test drive

Nice write up, probably going with these myself.
Do you have any pics of the install tool in use? Just hold against the sleeve and hammer it?

Sorry no "action shots" I was alone. I thought about the whole video thing ,but I was on a mission and wanted to be back on the road asap.

Ok the tool was made to hold the seal driver cup which is what saves the end of the sleeve from being mushroomed as it is drove into the axle. The side with the driver cup is held against the sleeve and the washers keep it centered as they are roughly the same size as the I.D of the sleeve.

The green lines represent the sleeve.

I would have destroyed the little 8" handle that came with the seal driver kit (or my hand) plus this makes it easier when it gets closer to being in the knuckle. The 5" x 5" plate on the hammer side gives a generous amount of area for a sledge to strike without going off target. The 2" round pipe is .250" and is easy enough to hang onto while swinging one handed with a 25lb sledge.

Congrats man! I remember hammering mine in and creating new curse words at the same time. Glad it is behind me. I was seriously sore the next day from swinging that BFH (16 lb sledge).

Nice write up.

Thanks man I appreciate it! It reminded me of changing out attatchment buckets on the excavators at work, so it wasn't a huge ordeal. I sure am glad for that tool though!

So is that pretty standard for all sleeves? Then a few tac welds to wrap her up? I was fear full of doing this on my last JK because I don't have all the fancy tools if I mess it up. But I'm tryin to build this one correctly....

The Nitro sleeves have about 3" of knurling on the end to bite into the axle tube. With the other brands they require a series of holes to be drilled into the axle tube and the holes get plug welded to the sleeve which typically just slides in. Then the end of the sleeve is welded around the outer perimeter. I didn't feel like drilling and chasing out all the metal debris from the tube, so I went this route.

The Nitro sleeves don't say they need to welded at all ,but I have confidence knowing that I have a few welds on there. Overkill and piece of mind. If you do end up going with the Nitro brand I would have a shop around you fab up a tool like the one I posted if your not comfortable welding. It makes the job easier for sure. I may post a drawing later of the material and design of the tool I fabed up.

I been looking into this. On other forums there are some threads on what can go wrong on these too. I wish I had saved the link. One pic showed the long side about 4 inches from home and MUSH ed. Get this, they used the side of a freaking Axe and a BFH. Then had to cut off the end and grind it to finish

Though I did glean this tip. And I feal this is the tip on these. When i do mine i will check it before starting the pile.

: On the inside of the tube about 2 inches on the inside of both sides. Where the factory welded the C's to the Tube. On some Jeeps there is a enough penitration weld to cause a raised area on the inside. Clean the Tube like Boss did. Boss that looks like a clean gun bore, nice. Then Feal with your finger BEFORE. If you feal it its alot. This can be smoothed out the Sleeve should then go about the Nurrels rather easy. from there its BFH.

Thank you ,that weld penatration was my concern and what may cause some issues for others. Yeah ,I saw a few of those videos and posts ...scary!

I have a working plan of material , dimensions, and assembly instructions I made for that driver tool if you would like them.

Thanks boss, I have access to a welder and what not, so this appears to be the same route for me... This will be one of my "saved thread for instructions" threads... Are you going to gusset it as well?
