with the steering rod removed, the motor is very hard to move. "takes 2 hands to move" (Steering wheel and rod move freely). Have tried all the YOUTUBE tricks that have been provided to no avail. motor still hard to turn. Does the power head have to be removed to change out the bearing in the steering shaft or can this portion of the motor be serviced without have to tear down the engine. Please advise if you have any insight, or knowledge of this repair. thanks in advance, (Steve).
