Today i changed my motor mounts because i though that by changing them the car would stop shaking. Apparently not, SO WHATS ELSE CAN IT BE IS IT THE TRANSMISSION MOUNT OR THE HARMONIC BALANCER? HOW DO I KNOW WHICH ONE ITS GOING TO BE. [/align]

 

Maybe since it is shaking at an ilde the engine is not running properly , such as an engine miss fire , or a cylinder is down on compression , If engine is shaking the mounts is not causing it to shake, they just control the engine and keep it in place. Unless your balancer is broke or you can physically see the rubber coming from between it , then i seriously doubt it is problem.
Do you have a check engine light on ?

its the harmonic ballancer, ive got a feeling and my feelings and gut instincts are usually right. Seriously mate, change the harmonic ballancer.

 

I got no check engine lights on, car runs good after 2500 rpm. So you guys think its the harmonic balancer?

 

where are you getting the shake, ive actually got the same issue and im leaning towards the harmonic ballancer. It seems like from stop to about 2k rpms it shakes with slight acceleration. Im sure after i change the harmonic ballancer, all will be fixed. The shaking is in my seat, so i guess it also could be a rear end problem or tranny problem. but thats me and my 2 cents. Im still betting on the harmonic ballancer.

 

Yea, same here, i feel it on the seat!!!

 

yea its the harmonic ballancer mate, let me know how it goes when ya change it. Ive got a broken back currently so im not gonna do it yet haha.

 

Have you balanced your tires? It seems to me if it was the engine it would shake while sitting still.

 

Changed the harmonic balancer and Its fixed, went to my local autozone got a Dorman for $60 .

 

see arent ya happy i told ya to trust me bro. When the stang is shaking.....change the harmonic ballancer lol glad it worked out well for you, now i can go pick one up too and see if it helps me.

To double check that we have the same problem
Under slight acceleration at low rpms your seat vibrates and it almost feels as if there is water in your gas and or if your losing traction. That make sense? This only happens to about up to around 2k rpms. at WOT you can not feel it.

Thats my symptoms and dimebag and i are betting on the harmonic ballancer as i was with you.

Im glad it fixed it for you bro, I KNEW I WAS HERE FOR A REASON JASPER =P <3.
