i done a wide track D30 to the front and a 8.8 from a 2001 explore to the rear ,this gave me plenty of width used adapters on the rear to keep the same bolt pattern,also got rear disc brakes with the 8.8 and limited slip,great axle combo and tough ,barnes4x4.com has the conversion kit for the axle swap for the 8.8,i'm also running 15x10 wheels ,the rear is alittle wider than a stock TJ jeep
