hi guys i have a 2000 xj that has been making a wurring noise from the back when giving it gas for a while now. i took the diff cover off to change the gear oil to see if that would help but when i did i noticed that the oil had a real metallic tint to it, clearly its on its way out. i figure a rear end swap would be my best bet on a limited budget. right now my xj has a dana 35 and i was wondering if i need to find another dana 35 or if i could use a dana 30 dana 44 or even a chrysler 8.25 and what would be my best option.

thanks for all your help
