I have had to "get the wrench out" more times than you could probably count, have your vehicle aligned the way you think it should be who cares more people give mechanics a bad rep because they THINK they now what they are talking about, when they don't!! Anything under a .5 degree differnce and you would never notice the difference in either lane, I have my ranger set at -.4 degrees cross caster which is less on the left, and I challenge anyone to feel any pull no matter which lane or what speed you pick! SO your "excuse" get real! Today for example I lost my a$$ trying to get a F-150 with 35x 14.50's on 22's to not drift or pull by getting the wrench out WAY too many times but hey I understand some shops are not honest! Some customers aren't either treat your mechanic with respect and he will return the favor!
Gijoecam, no jump felt, all manufacturers that I have seen include a small margin into their specs, the closer to a zero degree difference is better however it also depends on the area, what works here may or may not work there, I wouldn't call it an intentional Mis-align but if you look in any spec book it allows a + .5 degree cross caster, and again I say any GOOD alignment guy knows that some vehicles require a little more or a little less fudging one way or another.
DRAKE if it drifts a little and you can handle it then watch your tires for wear, if they wear good check you BJ's once in a while to make sure they are not dangerously loose, leave it alone until you notice a problem, If it ain't broke dont' fix it but be safe not cheap!!
I admit there are crooked mechanics out there, I know a few, but there are also honest ones! Just like any other profession, find a good mechanic stick with him, even if the other guy is $10 cheaper, if your are a good customer, that has a good honest mechanic, you will never lose that $10 you will make it up 100 times over by being treated fair, and honestly!!
