I drive a 2003 Malibu and the car runs fine but I have began to notice a harder ride especially when I cross speed bumps. My car has four relatively good tires from Walmart. Due to finances, I have two tires from one manufacturer and two from another. All of the tires are the same size. Should I bite the bullet and convert all of the tires to one brand and manufacturer. I had an alignment about 6 months ago, but my car continues to trembles when I get up to 80mph. It is controllable but it has become more noticeable. There seems to be a squeaking noise when I hit a bump. Previously, I was told that I will have to replace my Calipers and I was wondering what damage it will cause if they are not replaced soon. I had a transmission flush at 50,000 miles and I was wondering when should I have that process repeated. Is there a safe way to clean my engine without damaging any of the parts? What other maintenance is recommended to keep the vehicle working properly?
