I have hydraulic steering on my baby cat and am having some problems. I have noticed sometimes if i turn the wheel to the left real slow my motor will not move.......i have to give it a little jerk before the motor will turn. It pretty much acts like it is sticking. I have noticed this happens when the weather gets cold outside........not sure if that is coincidence or not? I have check the fluid level and made sure all the air bubbles are out. Any suggestions will be greatly appreciated.
