Hi! I have a 2012 Lexus ES350 automatic with 150,000 miles. When I accelerate above about 50 mph on the highway my car shakes and doesnt feel entirely stable. The steering wheel shakes slightly but its generally the whole car I feel as im driving. I feel like it make be something to do with the tires or they may be wobbling a little? I dont know. Also if i let go of the wheel it bears more to the right. I got my car in 2021 and it already had a wheel alignment. I do notice my tires wear out more so on the outside than in the center of the tire. I had my front shocks and struts replaced with a pair of loaded struts as well as a wheel balance. The mechanic said the rear struts need replacing also. I mentioned the shaking to him But he couldnt give me an idea of what could be causing it. But there's still shaking so I dont know if its the shocks and struts in the rear or its something else entirely. Do you know what this could be? Thank you so much! 😁
Try checking the tires, you said they were worn out unevenly. You do tire rotations so they wear evenly, but if not, the tire will wear out more. Check the tread on the wheels, see if they're almost flat or smooth, you can use a penny to test it out. Also check the tire date, if they are like five years old they probably need changing, even if they do not look bad. You bought an older vehicle so things like tires and batteries are just things you replace if the previous owner did not. Most people selling cars will not put a brand new set of tires on them. My dad had a 23 year old Benz, wheel would shake around 50-60, new tires solved the issue, they were losing tread.
Just wondering, does the shaking ever stop once you go about 70mph?
