i am at a loss to get ride of this rumble/vibration i get at 70+ mph i get on the freeway...i feel it in the stearing wheel ,gas pedal, the seats its not a massive vibration but you definitely feel it and hear it and it is not normal..the jeep runs smooth as a cadillac ride until i hit about 70 mph and it stops if i slow down or let off the throttle but starts right back up soon as i hit the accelerator again and gets worse the faster you go...
i tried to see if you can accelerate past it but it just gets worse and worse up to 90 mph and i backed off afraid something would break.

i really need to figure this out its my 1st jeep and i love it except for this problem.. it is all OEM i have done no modification to it other than put a cool air intake air filter on it to improve gas mileage

P/Ns for oversized:

K&N Gold: HP-3001
Mobil 1: M1-301
NAPA Gold: 1515
WIX: 51515
Motorcraft: FL1A
Purolator: L30001

Note that the K&N/Mobil1 are the same filters, same as NAPA Gold/WIX. Same brands are also great for OEM sizing.

Generally yeah, up here the Mobil1 unit is 2-3 dollars less. The K&N is literally a rebranded Mobil1 with a nut welded on the end.
