I have a 5030C; with only a couple hours runtime, my power steering is growling, I guess it needs fluid. Where does it go? I see one dipstick in the back left of the engine before the cab. I assume it's engine oil. I see one device with a rubber stopper cap toward the front left of the engine, looks like it may be hydraulic fluid. ANY help, please, pictures would be great. I don't see too well since my mini-stroke. Thanks very much.
