Yeah I had mine done yesterday too. They at first thought I was bringing it in for the column lock, until I told them it was washers. Apparently they hadn't had anyone in there for that yet. Mine worked out well also and no alignment. I don't notice any difference but then again the old washers didn't have problems.....yet. Glad to have it out of the way anyways! Now on to more spirited driving!
When I had mine done I stood beside the car and watched the mechanic and it took him 5 min each to replace the front and about a hour each to to the rear since he had to take most of the assembly apart to get to the bolts. He first checked the torque before he replaced. He told me that only 1% of Vettes were effected and that it was a the bolts not torqued enough but they replace all of them anyways.
