hey deeppaul
i just picked up my new rubicon yesterday and the steering is very firm on the trails.
i think its somthing im gonna have to get use to.
i road mine then i road my buddys and his has a lift kit and 27" mud lites on his and his seems to steer easyer then mine but i think its because your sitting higher that it feels differant.
another thing check your air pressure in you tires if there to soft it will make it harder to steer.
try pumping them up to 4 psi and see how that works.
