You need to count the teeth on the ring and pinion gear. Then divide the ring by the pinion. Were you planning on pulling the carrier out.

Why not just do the driveshaft/wheel turn check. I am not familiar with the 8.8 internals but I don't see a locker.

Its an open diff. If it had a ls it would have that pain in the ass s-spring between the spider gears.

I use 3 qts. full syn 75 140 I believe Im not sure that the open requires syn. As you spin your ring gear over it should be printed on the ring tone side of it ( your ratio that is).

Cause your 4 wheel drive system isn't meant for dry street usage.

The 8.8 should have the gear ratio stamped on the ring gear.

Thanks guys. I just find it awkward how it feels that way when my previous jeeps didn't. Thanks again though
