The biggest risk is ending up with pinion whine.

I don't know the science behind why those seals leak when they sit, but it seams almost all vehicles do it.

To prevent whine, pull both axles (repack anyway) and using an inch pound beam torque wrench check the turning torque of the differential gears.

When you put it back together carefully tighten the pinion nut to produce slightly more turning torque than you started with. This requires a holding device for the pinion flange and a good sized breaker bar; and some real muscle.

The results will be guaranteed good.
