Good morning,

I have a question about my 2004 Grand Cherokee. When I press on the gas and the rpms hit around 2000 I start to get quite a bad shimmy .. You can feel it in the floor boards not the steering wheel .. which makes me believe it is an engine mount ? Has anyone had similar problems .. I will be taking it in for a check up but just wnat to try and figure it out beforehand.

When I take my foot off the accelerator there is no shimmy.

thanks all

Bane

 

definetly sounds like a motor mount, i've explained it to people as feeling like a foot massager while accelerating...

might want to block your wheels, e-brake, put your jeep in neutral, and give it a little rev from under the hood so you can see if an engine mount is bouncing around

 

Check your motor mounts, but check your rim and see if you threw a wieght. It will do the same thing at different speeds.

Everything is ok now.
It was the U joint on the front driveshaft. The dealer replaced ujoints driveshaft all on warrenty .. nice guy.. Runs like a charm now.

Thanks for all your help
