I have a 2013 Tacoma. I installed 5100's and my truck still drove perfectly and the steering wheel was centered perfectly when going straight. I put new tires on the following week and figured it best I get an alignment. The tech said it was close to perfect, but they just fine tuned it. Now my steering wheel i would say is "not quite centered" when going straight. It seems to be off by I'd guess 5 degrees or so. If the steering system on a Tacoma was sloppy, I wouldn't notice, but its pretty tight for a truck. If I straighten it out that 5 degees, I go in the next lane.
I believe the alignment at the shop (Express Tire) was like $79.99 and they got me an extra $50 for 3-year warranty on it.
I could go back in and get them to fix it. Part of me thinks it may be a bit OCD of me. Oh well.
The technical question
I am wondering though, is adjusting the position of the steering wheel independent of the alignment itself? Like if they were to fix this, would it be a full front wheel alignment again (not that I care, since I paid for it and they do it for free) or can they simply adjust the steering wheel slightly and not have it effect it? Which makes the job quick and easy for both of us.
