I have a 2008 Chevy Malibu LTZ 3.6L V6 with 150,000 miles. After driving for a bit on the highway or anything similar in speed my steering wheel and car shakes on the drivers side. After that even when I’m going slow and decelerating it still shakes and feels like I’m running something over on each revolution of the wheel. Tires are a year old, back brakes and rotors done less than a year ago. Front brakes and front left rotor changed a few months ago. Just ordered a rotor to change the front right one hoping that’s a fix but probably unlikely. Just balanced all 4 wheels but it did nothing. Hoping me and my friend can do the job but I don’t even know where to go from here. Thanks to anyone who answers?
