A couple of weeks ago I took my vehicle to a place to have new tires put on the back only. After that, when I drove the car it started making a popping noise. When I turn the wheels, while driving, or while I am sitting still it pops. It also pulls to the left or right side really bad while driving and then other times it drives straight. I have already replaced the bars coming from the shocks going to the sway bar. I am at my witts end please help! Thanks for all the help.
