I've also read that It's near impossible to bend the C on a Dana 30 and what people bend are the tubes at the C, adding a gusset can change the strength of the C and actually weaken it.

Wheel it till its broke, then invest in a replacement...

 

Sleeves are more likely to weaken an axle tube than to strengthen. The weld-in type create areas of stress where the tube is more likely to crack and fail.

Hammer-in sleeves might provide some incidental protection, however, they do nothing for the rotational forces that most axles need to endure. If you review where axle tubes break, you will see that sleeves offer no protection. In fact, they limit the tubes ability to yield to stress, causing premature failure (typically at the point it connects to the diff).

A properly installed truss will provide additional strength, though still not as much as people think. Part of the issue on the JK axle is that the trusses available are not a one piece design, which limits the benefit they're designed to provide.

 

Hmmmm thanks for the info. I'm going to gusset it now and when the funds are right get a 44 and truss

 

man may as well have sleeves installed while doing the gussets. I had mine re-geared and c's gusseted, have to take it all apart anyway. Might as well. Cost me 400$ for the synergy gussets, sleeves, and lower control arm slides parts and welded.

 

Why get 44 AND a truss? A lot of Aftermarket 44s solve a lot of the weak points of the stock ones with larger diameter, thicker wall tubes and bracketed you as well as beefier Cs on either end

 

My plan is to go with the Nitro sleeves, which are press-in. Cool overnight in an ice chest with dry ice, clean inside of axle tubes if necessary using wire wheel or 400grit, then use BFH to install. May upgrade ball joints while I have everything apart. I have heard of (although not seen) many JK's without lifts or tires bending and breaking axle tubes, depending on how hard you wheel it. I am reasonably certain mine are "smiling" a little bit after 4 years of crawling rocks I had no business even trying (frame and skid plates tell the story.) Mine is still stock height, so a truss probably won't fit, besides I have also read that sleeves will help prevent deflection from heat when welding a truss later on.

 

If your axle tubes are even a few thousandths from being straight, you are not getting the Nitro sleeves in. I've even seen new axles where they won't go in because the heat from welding brackets on at the factory caused just enough warpage to prevent them from going in. Gussets will cause the same issue. You'll get them in part way and have to cut the rest off and grind. Dry ice shrinks them maybe .001" and you have about 10-15 seconds once out to drive them in before you lose that. Also, they do nothing to prevent the housing from warping when welding a truss on. I weld trusses on Super Duty axles every week and those are 3.75" tubes with 3/8" wall. Even with those I have to be careful and have a very specific procedure to limit the possibility of warping (and I always use a true bar). Despite all that, I have had to fix two where the tubes warped .003". It's enough that you will wear through inner seals and u-joints too fast.

 

This, exactly. Truss/sleeves on a stock axle are more about mental reassurance than actual structural support - though a truss will help. That said, if you are the person who is going to take out a stock housing without a truss, you will probably do it with one.

Plus, for what most people invest into their D44, they could sell it stock and put that money toward an aftermarket and have a smaller investment in the long run, and a much more worry free experience.

 

I was afraid of that, which is why I haven't pulled the trigger yet. Is there a way to tell definitively before disassembly? And if they aren't true, is there a way to get them there or is the housing trashed?

Also, going back to the main topic: In a perfect world, I would wheel the stocker until it fails, then swap to a Dynatrac. In this world, with my luck it would fail 9 miles into a 20 mile trail with no cell reception. I am just wanting to push-sleeve it because a full axle swap is years from being in my budget, I don't own a welder/haven't laid a bead in over a decade, and I wheel alone.

 

You can run a true bar into it. That is the easy way to know and really the only way. A local driveline shop may let you borrow one. You can also buy one. If you are not burning up inner oil seals or u-joints, you may be ok. Still a good idea to use a true bar before you find out the hard way.

I have some tricks on those sleeves though, so feel free to PM me tomorrow and I can help you out.
