I have a 2004 Grand Cherokee when your at a stop light it will vibrate a little dose anyone know what would be the problem it is a 4x2 4.0 some one said it could be the transmitting support bushing??
i did that no clunks i runs smooth while driving just when you get to a stop but when you take it out of gear it is smooth only vibrates when in gear?To check your motor and tranny mounts . Start the vehicle with the hood lifted . Put one foot on the brake . Put the Jeep into drive and then reverse and watch for a lot of movement of the engine up and down. You can give it a little bit of gas and that should make it really noticeable. You should have a little bit of movement. You may also hear a clunk when shifting from D to R.
