My Ford focus 1.8 deisel ghia vibrates/ rumbles when in gear and accelerating 1st being the worst and getting slightly better as I go up gears but still very noticeable.
Block wheels, front and back of one wheel should do it. With engine off, Put vehicle in neutral and check universal joints on each end of axle shaft at the front wheels by grabbing axle shaft and rotating it back and forth observing universal joints. there should be no slack in either joint. on either side of car. Also check all tires for lumps and bumps or odd wear patterns,
