How can I verify that a motor mount from my car is broken?

The motor mount has a rubber bushing that is compressed by the weight of the engine when in service. The damage might not be evident without the normal stress on the part. An X-ray would tell more.

If the mount was cracked or broken, you might have noticed more vibration than usual, or felt a slight clunk when accelerating.

Thanks. That makes sense. I hadn’t noticed any abnormal vibration or clunks, but did notice some degraded handling. I guess since it’s AWD, a shaky motor mount might have affected steering and handling?

Yeah, it can affect handling. The motor mounts on my RSX were shitty to begin with, and I get a lot of wheel hop when it’s wet. A lot of guys replace them with aftermarkets that are stiffer, but it’s a bloody knuckle job.

Thanks much.
