thanks for the link. it is not easy to turn it back to center. i did not bleed the system but i have filled to resovior a few times and the level doesnt drop any more.
It sounds like to me you might have air in the system and it needs to be bled.
I would suggest jacking the front tires off the ground, turn the wheels back and forth as far as you can like 50 times (with the engine NOT running), while checking the fluid level in the reservoir. This will bleed the system and make sure you don't have any air in the system.
With the vehicle running, it should turn easily, if there is no air in the system and the box and pump are good and the fluid is at the proper level.
I have trackick PS on 2 of my samurais....one works a little better than the other. On the best one, I can turn the wheels back and forth with 1 finger, with the engine running. On the worst one, I can still turn the wheels back and forth by using the palm of my hand, when the engine is running.
