It depends how bad the mount is.. The OEM mounts (like the majority of OEM bushings) are wear items and should be replaced ~100K miles assuming normal operating conditions, this mileage could be shorter/longer but that's a general rule of thumb. Even if you don't have any abnormal noise/vibrations the mounts could still be shifting under hard acceleration/braking which can lead to other parts wearing prematurely. There are certain parts that I agree "if it ain't broke don't change it" but I would highly recommend changing the mounts if they are at that high of a mileage. I guarantee at that mileage your mounts are squished down a good amount and once you change them you will definitely see improved feel/response when driving.
