[3.4 grape of wrath]

So I got the 12 bolt installed along with the driveshaft balanced and 1350 joint installed. A couple issues, the panhard bar bracket had one hole that was undersized quite a bit so I had to drill it out, no biggie. Drove the car and noticed right away some noises coming from the right side. Seems to be coming from the outer bearing. Noticeable when making left turns and during low speed forward driving. The noise is not present at all times though, kind of odd. Then I park the car in the garage and notice oil drippings on floor. Oil is coming from the 2 bearing preload bolts. Anyone have similar problems with this?
