After buying a 1980 300sd a few weeks ago, I decided to change the oil cooler lines( not a pleasant job) and then the motor mounts. The company I bought the mounts from gave me two different brands. The left one was a meyle while the right one was a Febi which had a made in china sticker on it. After getting the mounts in I started the car and put it in drive only to hear and immediate grumbling or grinding sound on the right side of my car. After spending a half hour trying to diagnose it, I looked down and my brand new out of the box motor mount made in china was flat as a pancake. Needless to say I am a little depressed right now since I have to go back and do this job over. What brand of mounts do you guys usually use in your cars?
