so yesterday afternoon. Just had my tires rotated. Fixed a flat and had the alignment done. Now. It sounds like there's a hole in my floorboards. Meaning the engine and or transmission noise is way louder on start up. But has a hollow sound to it, like you're listening to you're neighbors through a wall with a cup to your ear. There's also a faint grinding noise on turns and accelerating from right front. Like they lubed bearings with sand. Any ideas? They're closed to today. Taking back in tomorrow.
