Ok like that info Nuke, but now a new question. I have read that the destruction of the orginal as well as other problems are caused due to the original being used on a lifted JK.
Since you might be new at this jeep thing, let me offer some additional, general advice. Be careful what you read on the internet. I think the following scenario plays out all too often.
Someone with a jeep reads something on the internet. "37 inch tires will bend your front axle." They want to run 37s and they believe this to be true, so they go out and spend money on sleeves, gussets, truss, maybe even a whole new axle. Then whenever they see a thread with someone thinking of upgrading to 37s, they jump on and state "the fact" that 37s will bend your axle. They will go on to imply that you must do the same upgrades that they did. After all they spent their hard earned money on those upgrades and their momma didn't raise no fool!
Now what is the problem with this? Did they install 37s and THEN bend an axle? In 99% of the cases, no, they didn't. They read it on the internet and decided it must be true. They drank the Kool Aid and now insist that you drink it as well.
My own personal philosophy when it comes to off roading is pretty simple. If the failure of a part is going to cause a really shitty day on the trail, ie leave you stranded with no way to get off the trail, then that warrants spending some money on (assuming the likelihood of that failure is reasonable). If something like a clicking driveshaft or even a bent axle is just going to be annoying, but perfectly functional for getting you home, then I would rather wait until the DAMN PART ACTUALLY FAILS before spending money on an upgrade. (Straightening a bent axle is not all that expensive.)
And be careful with that DW issue. People will tell you, its this part or its that part or take it here or do this or do that. There is whole lot of BAD information on the internet regarding DW. Even Planman does not address or sufficiently address the role tires can play in DW. (And no, I am not dogging Planman - his videos are some of the best Jeep related info on the net!) My favorite thread was a guy who was so frustrated trying to fix his DW that he ordered a brand new ProRock 44 axle. He installed it, went for test drive and STILL had DW. It was the tires.............
