I own a 2001 Nissan Sentra 2.0 with the SR20DE engine if that matters. 124K on the odometer. About a year and a half ago I replaced the motor mounts with el’cheapo aftermarket ones. Went to pick it up from the shop and drove it away with nearly the same dang rumble it had before they were replaced. My mechanic informed that the AM mounts are not good but he put them on because I wanted him to. He did inform me of this beforehand but I didn’t want to spend $600.00 to by the OEM from Nissan. So, after that replacement I kept thinking I should have replaced the trans mount as well but didn’t. Mechanic didn’t think it looked bad. So I purchased an OEM from Nissan and installed it with the help of a friend. Was actually pretty easy.. Problem gone…smooth and quiet. After a month or two…problem is back again so I decided to just drive it until present day. I can’t stand it anymore. I purchased the OEM parts and they will be installed this coming Monday. Do any of you have any experience with these? My mechanic presumed they were Hydraulic filled but come to found out the OE ones are not.
