I would just watch your local jeep club forums or check craigslist. Even if you have to drive a few hours to pick them up, may be worth it.

If you can find them, you simply swap the entire axle assembly. Then keep your old axles for parts or sell them. They're not worth as much, but you should be able to recover some of your expense.

Hey bounty thanks for the advice, so do I just swap out the whole assembly on front and back with the 2.5l axles? Do you have any idea where I might find those axles i.e a good web site or something like that?
