I went on a test drive today after installing a one piece alum drive shaft in my 06 gt, and its making a very low humming noise. My car has Eibach lowering spring on it, so Im not sure if my car being lowered is messing with the angle of the drive shaft or what is going on.

Any help would be would be appreciated.

i have resarched this a little as i plan on doing the same thing lowering the car changes the pinion angle and you need an adjustable upper control arm to set it correctly if you search there are a few write ups on it good luck

Sounds like your pinion angle is off. Do you have an auto trans? What brand DS did you buy? Your gonna need an adjustable UCA to correct it.

Ok I tried setting my pinion angle to -4 deg after installing my new upper control arm. I used jack stands to level the car as best I could with loading the suspension. BBBBBBuuuuut the driveshaft is sounds like it making a vibration noise.... any tips
