trying to move it front to back. The top mount is easy to check. If your looking straight on at the engine...just slight to right of center is a black frame that comes off the back wall and attaches to a "round" bushing inside another black frame attached to the cylinder head...thats the top mount. Try pushing the motor front to back and look at the bushing.....should be NO MOVEMENT. If there is you will see how the inside of that mount breaks away from fatigue. The next mount to check is the bottom right, just near the crankshaft pulley..........if both of these are your "originals"....goooood chance they may be both fatiqued and the rubber broken. It IS a do it yourselfer if your a decent gear head. Parts availalbe from FCP groton.
