The best thing to do is get a flash light and look right into the rubber area see if the rubber is cracked if the rubber is cracked or broken then it should be replaced. Take a look at each one separately if you can . But that is the best way to really check the mounts. Another way to check is have or look into the engine with the hood up and watch the engine move when you put it in gear for reverse and forward but make sure you keep an eye on your feet and be cautious

Sorry had a funeral this weekend... ok so when we put this thing in gear it moves pretty bad.. My mother-in-law will not get rid of this thing so she makes us fix it she has had it since new and it has 189,000 miles on it... and got the pulley fixed...
Pontiac Mechanic: marcpod, Own collision repair advice replied 7 years ago
Sorry to hear that. I would recommend changing them all then if you can even if you do them a couple at a time the fronts should be the same time just like the Transmission ones. It will save you some money. Plus if you went to a auto body shop it could save you 30% or more because insurance rates prevail depending on your area.
