Where are you leaking from? Rear diff or axle seals? As far as traction additive it depends on if you have open diff or factory Trac lok

The factory manual says 20 ft# for diff cover bolts.
Here are some basic guidelines for fastener torque. Now things like soft joints, hard joints, static torque, dynamic torque, on and on can factor in, but here are the basic guidelines:
1/2 bolt = 78 ft#
7/16 bolt = 52 ft#
3/8 bolt = 35 ft#
5/16 bolt = 19 ft#
1/4 bolt = 9 ft#
