Hello, I have a 03 that I recently changed the driveshaft from, it broke about a month ago trying to launch the car, after replacing it, it started leaking, then I changed the rear shaft seal (didnt know I had to change that) but its still leaking. I searched in various sites and here too, but I cant seem to find what it could be, any help would be much appreciated.

 

A little more info, I noticed the driveshaft goes in about an inch more, and I have to pull it back a bit to bolt it back on.

 

Update, leak is gone, it was the shaft seal that was put in wrong.
