The pigtails should be placed on the spring perch with the pigtail closest to the REAR of the car with the ends of the springs pointing in the same direction (I believe to the passenger side).
So...I lowered my car a month ago and let it settle for three weeks. I went to get it aligned and the shop manager suggested I get a 4-wheel alignment. I told him I only needed a 2 wheel alignment since the rear is a fixed solid axle. He said I still should get a 4-wheel alignment, if I didn't, the front wheels wouldn't line up with the rears and the car could be doglegging (driving at an angle) and I would get additional wear on the tires. I've never heard about this. I aligned only my my front wheels on my old '98 and had no problems with wear or anything. I think this guy is feeding me S***. Help me out with this.
