I am trying to get clarification on your logic. If an axle can still bend or break with a sleeve , there by making sleeves worthless (YOUR OPINION). Then if you apply that to say C gussets, even someone with my limited experience (honestly it's limited) has seen C's still bend with gussets. Then they must be worthless as well.
There is a BIG difference between taking a long 2.5" tube that's only .25" thick and then adding a second tube inside of it and believing it's now somehow so much stronger AND, taking a short cast end forging and gusseting it up. I'll be honest, even the later is a borderline waste of money but to this day, I have NOT seen an axle C with a gusset bend more than it already had prior to the installation and have someone PROVE it. What I have seen are axle tubes that STILL BREAK in spite of being sleeved, just as you have. I have seen them bend and it be proven with a straight edge and I have seen them develop axle seal leaks because of the bend. But then, I'm all new to this Jeep stuff let alone JK stuff so you can take what I have to say for what it's worth.
True D60's are not all created equal, they can all be broken... So by your logic if it can and might or will still break it must be worthless.
Like I said, I'm far from being the badass that you clearly are. Don't know what you would consider to be "worthy" D60 but whatever it is, it sounds like it's something that I would consider to be worthless.
My point in all this? Its your opinion that sleeves are worthless. .. That is perfectly fine, many people share that same opinion. My opinion differ ' s and that's fine as well.
Just because you have the opinion they are worthless doesn't make it a fact.
And my point to all this is that I disagree with your opinion - that is the reason why we're having this discussion now. Since you seemed to have missed it, I am trying to show others why I think you're wrong. Unlike you, I know what it's like to build up a Jeep on a budget. I remember what it was like to get bad advice from guys like you who's only purpose was to eagerly encourage others to spend money on parts and just because you've chosen to buy it. If I'm guilty of anything, it's that I want to try and help others from making the same mistakes that I have, to make informed decisions about the things they're looking to buy and with any luck, based on things that I have seen and have learned over the years. In the end, people will need to determine for themselves if anything I have to say has merit. Of course, I don't know you from Adam but there's no doubt in my mind that you're badass and an expert on all things Jeep. Ultimately, people reading this thread will spend their money on their Jeep, however they see fit and to me, that's perfectly fine.
