the engine in my 06 Grand Prix rocks when you pull on it from one side...such as the alt. brace bar. I know the mounts should give a little, but how much play should there be and how to know when to replace the mounts or bushings? The rubber bushings are still soft. This is the first fwd vehicle I've owned so I'm not really sure if or how much play in the mounts is normal. It just seems like you shouldn't be able to grab the engine and pull it toward you like you can with mine. I would think it would throw the engine out of balance when driving and I hit a bump. Is this normal? The mounts don't look cracked.
