It sounds as if it is the pinion seal. That not a real hard thing to replace. The steps will make it sound like a lot but it's really not that bad a job.

Before replacing a pinion seal make sure the fluids are not just running down the drive shaft and "dripping" there.

You will need to pull the drive shaft loose from the pinion. Mark the driveshaft alignment to the pinion by just making a single mark on both.(Don't forget to run tape around the bearing caps after you get the driveshaft out) this will prevent you from loosing some of the needle bearings.

Removing the pinion nut will be the hardest part, it's is torqued to spec. And you may need an impact wrench to break it loose. Remove the "cotter" pin 1st then remove the nut.

Either use a pinion puller (if you have one) if not strike the pinion flanges with a good ballping hammer gradually it will move forward and slip out.

Pop the seal off and then tap the new seal into place. (These can be a little stubborn at 1st if your not using a seal installer.) Just take your time on tapping the seal into place.

Slip the pinion back in (line up the splines) torque the nut back into place.

Replace the drive shaft.

As with any automotive maintenance practice good safety and use protective eye gear.

Good Luck
