Its kind of hard to tell from the picture and it's angle, but looks to me like the rubber block is seperated from the metal base plate and the engine bracket is riding a bit low and touching the base plate brackets. That is, it look exactly like mine did. The procedure to replace it is not that hard and its a 30 minute job as long as all the bolts all come out easy. With the number of miles on yours, its probably worth doing and seeing if it fixes your problem. What does the top mount look like? Probably worth doing that one too while you are at it.
