I just installed a Ford Focus Electric rear engine mount. YOU NEED THIS IN YOUR LIFE!
When my original failed at about 120,000 miles, I put a 70 durometer AWR in it's place. Buzzy as hell, but I lived with it, because the shifts were so much better.
Fast forward 6 years, I'm at 211k now, and I read about the Focus Electric mount. Rockauto had them for $19, so I thought Why the hell not?
OH. MY. GOD. It's night and day! It's the best of both worlds! You get the positive shifts of the AWR, but the good ride, comfort, and low noise of the stock unit!
AWR and Corksport are finished in the rear motor mount game! This is where it's at!
I ordered the Westar EM-4110 which is the generic replacement for Ford PN CM5Z6068A. You'll also need the correct Ford bolt, part number W500545S900.
