I took my OB in for oil change and was advised there was uneven tire wear and they would check to see if it needed an alignment. They did the alignment. Mileage was 35000. When I got the car back, the complimentary multipoint walk-around inspection sheet showed all tires OK and no wear pattern/damage was noted. The alignment printout showed that, before the alignment, the right rear toe was -0.01 in., which was 0.01 in. off the specified range of 0.00-0.08 in. There were no problems on the left side and the right front was within range. When I asked the technician about it, he said that, when he corrected the right rear, the right front went out of range by .01 and so he had to adjust that as well, even though before the adjustment to the right rear, it was in range. I don't know if this makes sense and if the alignment was necessary - I hadn't noticed any problem steering, etc. - or if it was just done so they could add to my bill. Any advice would be appreciated.
