Alignment Question

I just replaced the left and right outer tie rod ends. I took the Truck for an alignment and they supposenly did the job. BUT...... I notice that when I turn a corner the steering wheel doesn't come back automaticly when you let it go. It come slowly to center position. I also looked down the front of the car and notice that standing still the car seem to have the front outer edges of the tires at a snow plow sort of . (not that bad but noticable. They did have a computer read out and all the specs seem good. Any ideas??? Thanks for any replies

Take'er back, that's my suggestion. They did the work, could've been a misread spec sheet, but I'd take it back and have'em redo it.

One other thing that can cause "Memory Steer" on that model is a siezed ball joint. Remove both front wheels and seperate both tie rod ends (L. outer & R. outer) and then see how hard it is to turn the spindle with your hand.
