Pinion leakage problem

Pinion leakage problem Car developed a pinion leak a few weeks ago (decent sized one). Rear was redone about 6 years ago by DTS in Warren MI and haven't had an issue up to now.
took it to them on friday and they changed a pinion seal. still leaking about the same amount.
I lowered the car this spring (about 1 1/2") but didn't use an adjustable panhard bar (rear was only off about 1/2" side to side so would have needed 1/4" of adjustment. figured I could get away with that. Did this possibly cause my problem?
car has 65k miles on it. makes about 380rwhp with listed mods. It isn't drag raced from a dig hardly ever, but is driven "spiritedly".
Any rear end gurus have any ideas where my problem might be?
no noises of any kind coming from rear.

No, and sometimes fresh seals leak some. Id make sure the level is correct (not overfilled) and watch it closely. If it continues you will need to swap seals again. I prefer an ac delco oem seal. Also, inspect the mating surface on the yoke and I would permatex the seal into the housing.

Factory 10 bolt. DTS put in a Trutrac and 3.73 gears 5-6 years ago.
Rear never leaked a drop until the day of the dream cruise. There was a puddle of about 2-3 tablespoons under the car. About the same size spot after they changed the pinion seal.
