I had some engine vibration so I checked my mounts and sure enough they were bad. I replaced them with some made by anchor. After the end tall there is still some vibration that can only be felt between 1500 and 2000 RPM. I don't really feel it when I'm driving untill the revs come down when coming to a stop. A mechanic told me that the mounts were not sitting in there properly and some of the vibration way be due to the aftermarcket mounts instead of factory. My question is, how do you properly line up the engine and mounts? Has anyone else used the aftermarket mounts and had this problem?
