PHOTO DIY-ENGINE MOUNT REPLACEMENTS
Well, the day finally came for me, when my "Einspritzung" became a "Diesel". (106,000 miles)
Yes, the usual symptoms of "Smooth idle, until you move it into gear, then..... VIBRATION".
After performing the confirmatory "acid-test" (popping open the hood, have someone apply the service AND foot brakes, all the while pointing the car in a "SAFE" DIRECTION, have the helper gently "REV" the engine on and off, all the time looking at how much Rotational "movement" there is in the engine. You will know what "excessive" is. Mine was "Rockn' and Rolln' " SEVERAL inches up and down. YEP!! BAD ENGINE MOUNTS!
OK. TO be clear here, this is NOT the specified WIS method of mount replacement, but it IS the "STANDARD" method used, even at the dealerships.
Please consult with your Model Year/EPC, to confirm if BOTH your mounts are the same, like mine, or whether your year DOES HAVE a Right/Left numbers.
As a special note, make sure the "Points" on the mount line up with the "Notch" on the lateral side of the engine mount. This prevents the mount from "rotating".
The usual CYA stuff- I am not encouraging, nor discouraging anyone from doing this fairly "straightforward" job. DO ANY WORK AT YOUR OWN RISK, AND OF COURSE, USE INDUSTRY STANDARDS OF SAFETY, ESPECIALLY UNDER A JACK=STANDED CAR. I CLAIM ZERO EXPERTISE NOR EXPERIENCE. I am a "novice" shadetree mechanic.
