Wondering, i took my bent wheel to get fixed balanced all 4 tires and now my car vibrates a little more than before trying to fix my prior minor vibration problem.. They broke 1 lug nut in each front tire, so its running with 4 only on fronts. They are 19" on cts coupe 3.6, they also removed a half an inch spacer from the front from one side and not the other.. What could be causing my front vibration after 45 more less?? Thanks, im soo fustrated! I tried fixing my bent rim and all this stuff happened :/, it was better before... Any comments ideas?
