Had an alignment done yesterday after a new set of tires. Here are some of my questions/concerns:

1. Previous alignment was done in March of this year at the same location. But today front left toe was "out" at 0.13 degrees.

2. Right rear toe is at 0.33 and they claim it can't be adjusted. What could be causing this?

I drove mostly highway miles (over 400 a week) with the other 50 miles or so per week around town.

Any help would be appreciated!
