Ever since I changed my front bearings years back my truck has pulled left. I used the trick I learned here where you back the bolt out except a few threads , leave the socket on it and use the power steering to push the bearing out. Just got brand new tires and front end allignment 2 months ago , but it still pulls left. So today I took it back to Goodyear and they say its not the allignment but they can't figure it out......

I know their probabaly a bunch of kids working back there with not much experience. Any ideas as to a possiable cause? It makes it a pain to drive as I'm constantly adjusting my steering wheel as I drive.
