Cost to replace motor mounts on 2004 Malibu classic?

To replace a motor mount ( it's recommended to replace all of them at once, due to the most costly part of the repair being the labor, the engine is actually unmounted and hoisted back up when finished ) it will cost roughly $130. for one, and usually will run about $520-550. for all four. Since motor mounts usually wear at about the same rate, it is not recommended to change one at a time.
