Hi All, my car has 155k with the original engine mount and trans mount. Going to replaced it to this weekend.
Here's a video of my car for those wanting to see or how they can tell if the mount is bad.
When starting the car, I can feel the whole car shift left and right. If the AC is off, rpm is around 400-500rpm, if AC is on,can't feel the shaking.

Already replaced the lower ball joint, bushing to lca, Tein lowering springs, new sports suspension.

Definitely time to replace those parts! I've seen them so bad on other cars that the engine will actually hit the hood and cause it to move.

I was wincing with all those repeated revs in attempts to make the engine move. I think a better way to check the motor mounts would be to apply the brakes and then give a short/quick pump of gas pedal. If she moves/shifts (like yours did), then probably a bad mount or 2.

Off topic---but the engine doesn't sound too "healthy" on the video. Maybe it's simply the video/audio quality, but to me sounds like an exhaust leak or valve tick or something? At :47 I felt ill! Sorry to comment critical things, but also surprised others haven't mentioned anything on how it sounds?

Are you/did you replace them yourself or have someone do it? I would like to do this 'just to do it' since my LS has about 150k on the ticker.
