I have noticed my jeep has started to have a vibration when i am at a stop. it isn't always there but occasionally it shakes. when i accelerate i can not feel it anymore. Sometimes it is so bad that my sun visor shakes.. any ideas or similair cases?

 

cant say i have but when i first start mine it rattles. does it happen when your jeep is warming up

 

no, it does it after ive driven it a bit it seems

 

Hmm, I don't know, but right off my head I'd check your motor mounts and trans mount.

 

yeah motor mounts is the first thing i thought. unfortunatly im not gonna get to see my jeep for another month but i will check then... if it gets worse ill have the wife take it to the stealership.

 

no, its not low rpm... i know that feeling maybe torque converter.

 

One thing to keep in mind with the 3.8L engine vs. the 4.0L engines. The new 3.8 crankshafts are muck lighter than the 4.0L cranks. Because of the lighter rotating mass there is more NVH emitted. I also feel the vibration while stopped in gear, feels like the engine and trans have poly mounts LOL.
