Default Swapping to ZR2 rear axle

I finally got my zr2 rear axle installed yesterday. It has 4.56 gears and a Detroit True Trac limited slip. Now all I have to do is swap the front differential out for my Zr2 front diff with 4.56 gears. But I'm gonna wait until I have time to swap (just about all) front suspension components before I swap the front diff. I have all the parts, just no time to tear my DD apart. Everything on the axle was plug and play. I did have to swap the passenger side bake line out from my old axle to the Z axle, because the Z's was cut. Then I swapped my almost new emergency brake shoes from my old axle to the Z. Here's a few pics, I'll post a few more up tomorrow.

You didn't see my Mickey Thompson Baja MTZ 33's in the last pic? lol


If I get the chance I'm definitely putting 35's on, I'll have to do a lot more fender cutting, but they'll look completely BadAss!!!!

Here's a side picture of the tire sticking out and my new Street Scene Speed Grille!!!!!!!

I can't help it that he had a great idea!!!!!!! Plus, WolfPack actually found both axles for me....lol. It was 500 big ones for the front diff and rear ZR2 axle both with 4.56 gears and the rear has a Detroit True Trac. Though I'm not sure if the locker works......... Couldn't get the other tire to spin when one was spinning while barely touching the ground. Spinning tire was on rocks and other tire was on pavement. Maybe I wasn't giving it enough power to engage? I was trying to go up a rock hill sideways where the train tracks sit, right next to a road. It was pretty steep, but they both spun simultaneously when I did a burnout in the grass, if that counts as a burnout.....

I didn't need to. The u bolts that came with my Trail Master lift worked just fine. And I think WolfPack's stock u-bolts worked fine as well. But he might have used the u-bolts off the Zr2.

Also, does anyone know a trick to getting the driver side CV joint off a ZR2 differential? I've used a long pry bar on it, but it won't budge. Might have to get out the air hammer, but I don't want to ruin the CV unless I have to, cause I don't need it.

I've heard that you need to tap on the cup while you pry to get the clip to bounce out of the groove. Haven't tried it myself.
