Vehicle pulls left when accelerating from a stop. Brand new tires and front end alignment less than 1,000 miles ago. I personally have not looked at the vehicle. Any ideas?

Switch the two front wheels, left to right, then see if the pull goes the other way. If it does, you will also find it pulls in the opposite direction when braking. That combination of observations is due to unequal rolling resistance of the tires, and is often solved by switching them front-to-rear, then leaving them there.

Also, if you have a printout from the alignment, post the numbers for "camber", "caster", and "toe", front and rear, and I will interpret them. Cars today are very picky with those adjustments, and every alignment computer can read to.01 degrees. That is a huge improvement over the plus or minus 1/8 degree older stuff could read to. Many mechanics set their aligners up to only read to the tenth of a degree to make the job go faster. That can round off some readings and mask a pull that should have been adjusted out.

CARADIODOC, thanks for the reply. I will post the printout tomorrow of the alignment and results of switching tires from left front to right front and vice versa.

Those numbers refer to "toe", the direction the wheels are steering, and affect the centering of the steering wheel. I need the "camber" numbers for the front wheels, left and right. "Caster" would be nice to know too, but that has very little effect on pulling on front-wheel-drive cars.

CARADIODOC, there are other #s to the upper left + right of those toe in ones I gave you, they read the same for the before and after, -0.08, 0.08to-0.16, 0.16for left side, 0.08, -0.08to-0.05-0.05right side I'm not sure these are what your looking for. This paper printout makes no mention of caster or camber adjustments

Oh well. I was hoping to find a clue, but try switching the front tires side to side and see what happens.
