so my 2006 rubicon 500 es steering is all of a sudden stiff. i rode it about a week ago and had it parked outside and it would steer fine then. went to ride it today and the steering is very hard to turn like tires ar flat. i jacked it off the ground and it is easy to turn but harder than normal. it has been raining a few days of the week but would that effect it? what could it be? its not locked in 4wd.
