Even though this video is 9 years old, I just wanna thank this man for educating me. It was very helpful. Thank you.

If your car is vibrating a lot at stop lights and shifting it into neutral causes it to smooth out, that's a good test pointing toward motor mounts. Useful for situations a little more subtle than illustrated here.

As a preventative measure, I always change all engine and transmission mounts when one goes bad. They usually all have wear on them and fail in short succession of each other.

Thank you for sharing that A BAD MOUNT CAN AFFECT STEERING. I think that might be my issue because I noticed the car slightly veering to the right after the last couple alignments. I couldn't figure out why it was doing that after driving away from the shop each time. Never heard this from anyone else, including any mechanics. All the extra tidbits of information is handy so thank you! Keep up the awesome work!

It took me a while to realize my front mount was bad. Just changed it.
Insane quality upgrade, didnt realize how bad of a delay it had before when id press the gas pedal. No more vibrations, no more weird vibration noise, drives way nore stable. Now my 26 year old corolla feels like new

Hi I'm from London UK and my automatic car is in the garage. I took it in to replace the break pads and discs and they rang me to tell me to replace the engine mounts too. I thought they were trying to rip me off and get extra money until I watched your video and realised that I have been suffering with bad enging mounts because of your excellent description. thank you.

+Bri Graham, I cannot reply to your comment for some reason but watch the video and see if the engine shakes when you go in and out of gear or start it up. It will shake just a little normally but it shouldn't shake a lot. Let me know what you find. It could also be shaking because it is idling poorly with a possible misfire. Do you have any check engine lights?

One of the first things I do is replace mounts on second hand cars quite often regardless if the car has done over 50 k - makes a world of difference and often neglected. Good video.

Hey Chris. You make all your repairs look so simple you really encourage me to go out and do some repairs on my 1996 Ford Contour myself. Like this video on diagnosing and changing motor mounts. I now know what my issue is. I am still not brave enough to do it on my own yet. But I am getting there. Thank you and God Bless

[ianmccoy]

Thanks man, I have been having a clanking sound when I accelerate and change gears and i went under my car and the transmission mount was missing a bolt, so I replaced it and there is no more clunk.

[crowemurdock]

Very helpful!!! Most fix it videos only show the repair but hearing the noises and seeing the before and after results REALLY helps! Thank you so much!

[whoami]

I've spent over seven Grand on my car fixing it over the course of many years watching just your videos and it has been so satisfying to learn everything that I have and to be able to do everything by myself now with that being said I'm literally on my way to go get motor mounts at the moment

[ecolegio]

Man so nice to see this old vid of yours and notice how much you´ve evolved! Nice job... I love your videos.

[jonathanjimenez]

I just replaced the transmission mount on my car that was pulling to the right when accelerating. Now the problem is fixed. Thank you for uploading so helpful videos like this one.

[emmanuelu.]

Man, this is a great video! I just got a car (used) and when driving, I used to feel that weird shaking movement. First they told me those were caused by oil entering to the spark plugs... But then they said they were fine, it was just the motor and transmission mounts. Your video explains all. Great content!

[tinamarie]

Thanks so much for this. i just got my car diagnosed and i was wondering how the issue i was having related to replacement of engine and transmission mounts. now i totally get it and the auto shop is right on point. makes me feel a lot better about a $900 repair...i guess. :(

[xof_industries]

This is exactly what’s going on with car! Thank you so much for such an awesome vid, short but straight to the point and super informative!

[bettykalya]

Very informative. When on reverse, the engine conk's.. ...I thought it was a gearbox problem, now I know it's the engine mounts. Thank you for the video clip.

[Movie]

A few days ago I heard a clunk sound when my car(Toyota Aurion 2007 150.000km ODO) switched from reverse gear to driving gear. It feels great now to know what to fix. It's really helpful video. Thank you much Chris. Cheers!
