This part is a winner. Trust me, unfortunately I'm an "expert" in this area. Buy this if you want the vibration to stop and you don't have to keep replacing it. I'm almost embarrassed to say I've changed that side motor mount 5-6 times before I bought this brand. I just a few days and the other just a few weeks. I bought this part from AutoZone and because you get a lifetime warranty, every time it broke I went back there and got another one for free (however I had to pay labor to replace it every time). I'm not a mechanic so I have to explain in simple terms what I saw. The main reason the previous part kept failing was that the "distance" between the top (silver) and the bottom (black) was very small, and as soon as I hit a few potholes there was no space between those two pieces of metal Adjust so that they touched, so the most annoying vibrations started (especially when the engine is cold). The engineer of this part or the company that makes it figured this out and increased the distance between the two so even if the top goes down a bit it still doesn't touch the bottom so there is no vibration. The quality of the rubber part (the top of the black piece) matters and seems to be better here. According to my mechanic, there is oil in this rubber. So if the rubber breaks there is no resistance and the top (silver) part goes down so it approaches or touches the bottom (black) part. Although my explanation is terrible. I think you understand This part, regardless of brand or design, is not easy to install due to its location. I highly recommend this product!
