7.25 Rear End Question

Ya like Demonic said, a new pinion seal and bearing are in order. The seal leaked all the fluid out while it was parked and one Wal-Mart run later I have a rear end louder then a hound dog. Bought bearings and seals to do the whole job because of the "while i'm here" factor. Its just been a few years since my last rear end job and my service manual is now where to be found. Sadly I don't have much in the way of impact (Compressor is down right now), so some PB Blaster and fatty cheater is what I see in my future. Thanks for all the advice, not to pull the vehicle on top of myself is no sh*t, I though I was getting somewhere for a second but it was the car moving...
