It's a D-30, 4.10's, lock right. After I park the rig when I come out there is always a little puddle of diff fluid on the ground. The axle joint has a little play... I should replace it....but would that cause it to leak that much? Oh yeah the gears, carrier and locker are fairly new

TIA

:p

If it's leaking that much...time to replace the inner seal. A PITA.

Here is a good link for chaging D30 axle seals:
