When I cranked the bars on my 04 I got a slight shudder type vibe on heavy acceleration from a stop or low speeds. Never encountered anything at highway speeds or when holding any constant speed. That doesn't mean it isn't causing you problems....just my experience I had with my own truck. My guess is that the root problem is somewhere else and the level has simply elevated it to the point where you have noticed. I personally would start by having them balanced.
Also, just FYI, that appears to be your steering rack leaking rather than your pump/reservoir. Unless it's leaking from the bottom of the pump down onto the rack. Mine was actually leaking where the hoses connect to the bottom of the pump/reservoir unit when I bought it. I had to replace the hoses and also replaced the factory squeeze clamps with worm gear clamps....problem solved for me. Good luck!!
