when i go into or come out of a slow left turn my steering wheel goes back and forth, not a whole lot but i can feel it in my hand. it never did this when i bought the truck so its not normal. im thinkin wheel bearings but i could be wrong. any advice? could driving my truck like a ferrari be contributing to the problem? if it is i guess ill have to be an old man in the turns but smoking ricers is hilarious! esp when i fill their car with smoke from the side dump.
