The motor mount was slightly larger than the one I replaced. I would have rated it a 5 except for this. It definitely was of the same quality so I expect it to be good. I had not noticed a difference in driving. It was due to a mechanic recommending the part be replaced that I purchased this particular motor mount. After looking at the "beat up" mount I removed, I definitely understood it was detrimental to the operation of my vehicle. Thank you for the reasonable price and timely delivery of the mount.
