well i took my car to get a balance and rotation done. they aparently didnt do the rotation and only balanced the 2 fronts. they then told me it wouldnt be much sense to balance out the back since my left rear wheel was bent. then they said, well actually the 2 left side wheels are bent. i wasnt charged for the service, but why would they have said they balanced the front but not the back if they were both supposidly bent? any thoughts here? should i get a second opinion?
