steering issues

ok. had the right front hub bearing replaced about 2 weeks ago, and today, the steering started getting "tight". by this, i mean that it almost feels arm strong. checked all the fluid levels, and all was good. made sure there was no air in system, and made sure there was no leaks. doesnt matter if its at idle or while driving, could it possibly be the pump or steering box? any help would be greatly appreciated. If its a bad thing, I need to get it fixed asap. :helpme:

This would usually be the power steering pump. You could try jacking up the front end and seeing if it is still hard to turn with no weight on the front. If it still turns very hard, maybe the steering is binding somehow. If it turns a lot easier, I'd replace the pump.
