Re: Strong Vibration at Idle Below Rear Seat
Do you have the ORAII package with the skid plates?
If so, check for properly tightened plate fasteners. Just bang on the plates and if there is movement and/or no solid "thump", they are most likely loose. If they are loose, use Blue Loctite on them before you cinch them up.
