need to know:

Engine

Transfer case model

stock tire size??

any lift or other modifications??

can you feel the vibe - front? rear? left? right? steering wheel?.

how severe is the vibration?? Any noise happen with it when you feel it??

mileage

and maybe some other bits along the way.

Some most likely possibilities off the top of my head would be wheel bearings, front axle cv joints,


For the rear lamp failure, check the the high mount brake lite for three working bulbs. even one burnt out will set off the dreaded ''rear lamp failure'' message.

Have you checked for engine codes?? is the check engine lite on?? Sounds fuel related. sediment could have gotten thru to the injectors. Try some fuel conditioner for fuel injection systems otherwise you may need a trustworthy shop.

this should give you a place to start again on each of the problems anyway..
