Tire spec questions.

Can anyone explain this to me better then "your frame is twisted and we accounted for it, that's all you need to know". I know what camber, caster, and toe is. not sure about actual and before and if my axles are outa wack or something. Just got new tires on and this is the sheet I got from an alignment. Been super smooth everywhere for the past two weeks but now a slight rumble t freeway speeds but really just want to know about this page.

Anything is appreciated

Thrust angle has to do with the alignment of the rear axle in relation to the vehicle. Basically what it means is that your rear axle is pushed forward/backwards on one side. This isn't a big deal really, .21 degrees is almost nothing and I doubt it has anything to do with your new issue.

Before and actual are the readings before and after any adjustments are done. I'm not sure why you paid someone for an alignment when the only meaningful adjustment that can be made is toe. There are a ton of threads on how to check and adjust your front toe in the tech sections.

If you are that concerned find a spot on your fame that is the same on both sides, like the front leaf spring hanger. Measure from there to the center of the axle tube. You can loosen the u-bolts. Then use a pry bar or ratchet strap and see if the axle shifts enough to change it. If it were me I wouldn't bother dealing with it.

thank you, I didn't pay them. We know someone who works at big O where I brought my tires to be mounted and balanced so he gave me a nice deal and a free alignment. plus i feel its decent to get a pro one once a year just cause. and I normally do the driveway method anyways. but thanks man you cleared up some stuff for me.

From what im seeing on that page your driveway alignment seems pretty bang on bud.
