Question on symmetry of our vehicles

I am kinda stumped right now. I went outside to take some measurements on my 2008 5 lugger. What I found has me frustrated. It appears my passenger side rear tire sticks out a half inch further than my driver side rear. I got my measurements by picking identical spots on the frame and measuring out to identical(tread pattern) spots on my tires. Are all Tacomas like this? I thought they would be exactly the same?

 

Another way to look at it is the box sticks out 1/2 more on the left. You're just a 1/4" off, move the box 1/4 in to the right and your good to go. Curious as to why this matters?

 

Guess I shoulda read a little closer!

 

Check your axle and make sure it is aligned down the middle. It could have had a spring replacement and was not reinstalled correctly.

 

yes it was bought used from a dealership about a year ago. I got the carfax on it and it said it had never been in a wreck. I checked the lines of the vehicle,doors evenly spaced,bed evenly spaced from cab etc. I have not replaced anything on this truck.
