Alright, so I've been having this weird semi-loud vibration that is starting to get annoying now. The weirdest part about this whole thing is that it is intermittent. Now it only happens when the car is in reverse and idling in drive and idling in park. If I put any sort of load on the engine it goes away.

I recently replaced the rear motor mount but that didn't seem to do anything, plus the one I took out didn't look bad. When I removed the rear motor mount, however, I could move the engine quite a bit (maybe like 2-3in) back and forth. Is it supposed to have that much play? I'm thinking my other motor mounts may be bad because I don't know what could possibly be causing this noise. The other possible part is the transmission but I feel nothing else when gears shift and what not. I guess it could be CV joints as well but I don't think it would be intermittent.

Anyways, I have tried recording the noise on two videos maybe someone with more knowledge on the dart could help me out.

Here are the videos:



Thanks in advance for any help!!

There are 3 motor mounts, left, right, and rear. There is also a procedure to adjust or center the engine. Do you need info on how to remove/install any of the other mounts? Or info to center the engine?

My Fiancee's old car used to do that when I put it in drive... I dont think its engine mount related as much as maybe a transmission issue... I would guess the torque converter maybe? Im not really keen on all the inner workings of an automatic transmission... Mine is manual.

Yes I'd like the information for the left and right mounts and how to adjust or center the engine. That would be awesome.

83k miles (yes its a lot, was being used by 2 people (my wife and I) for work/leisure travel). When I turn on the A/C the vibration gets a little deeper then settles back out to normal. It happens when I turn it on.

I do not think its the transmission or torque converter causing this issue. It only happens in Idle/Reverse and there is no other problem with accelerating, switching gears, or even flooring it. There are too many moving parts in those components for their not to be any other related issue, although I guess I can't rule it out completely.

Appreciate the responses, been a little busy. I just have a feeling it's the mounts though because when I let off the gas and let it drive itself then hit the brake, you can hear the vibration move when braking and then it takes like 4 seconds to finish rocking and goes back to steady vibration. It's really odd that's why I think it's the mounts.

At least you have a good idea on where to start! you can get yourself some new motor mounts from Deyeme Racing! They make 3 different styles too! Flex, Firm and billet aluminum!

Could someone be amazing and send me a picture of the inside of the passenger side engine mount. All you have to do is take off air filter cover to get the rubber flap on the mount. I think mine has collapsed and that's what is causing the vibration issues but I'm not 100% sure without anything to compare it to.

Deyeme Racing Transmission & Side motor mounts: Installation & Comparison to OE (OE's pulled after 26k) should at least give you an idea or at least point you in the right direction. When I pulled my transmission and my side engine mounts out they were both deflated and this was only around 26k miles. Let me know if you need any other pics of the mounts and I will try and get some when I get home.

I appreciate the link but that post didn't have the picture I need. I need the inside of the passenger side engine mount so I can confirm that mine has collapsed. I'm 90% sure it has but I just want to be 100% before I order one. You get access to it by removing air filter cover and then pulling back the rubber flap that covers it. I need a picture of the inside of the rubber flap.

Patience is a virtue... @youngsmith53 said he would get you some pictures when he gets home from work. He is a man of his word! And if you are really in that much of a hurry then go to a dealership and ask them if they have one for you to look at and compare to yours! Then you can see the difference. There are such things as returns, so if they make you buy it, just take it back a day or two later and get your money back before buying the better deyeme one!

Yes, he told me to let him know so I was letting him know...

how many miles on your dart? we've had members report the mounts going bad as early as 25k miles

what happens when you turn on the A/C?
I have 150,000 miles and nothing out of the ordinary it just makes noise at certain angles and what not but I’m not sure exactly if it’s the transmission mount which I think it is but gotta take it in to get a full check on it
