Oh wow thank you so much guys!! I'll definetly get that balanced asap,also one more thing, this used to happen a lot but not anymorenow,first off let me say I have a tranny and transfer case leak, itsnot that bad, always give it the extra oil every other week, that being said about a month ago when the JEEP was idling under the drivers seat and or passenger seat it started to rumble like pretty bad, it idled at under 1000 rpm at bout 750 I would say, it does it occasionally in the first 5 minutes of driving, it happens right when u go into neutral on a stop, as soon as I press the gas , the rumble goes away, its very weird and hard to describe, it has its days when it does it but then has its days when it doesn't. I did the 2 by 4 check and listened to the engine, tranny and transfer case, all sounded ok but the skid plate was the thing rumbling I think, maybe all I need is some rubber?? Why would it be rumbling that bad? Thanks again folks!!
