:{ Looking under my truck today I noticed a slight amount of fluid on the ground and upon inspection I found fluid all over the top of the steering box in the vicinity of the adjusting nut. I checked all nuts for tightness and they're fine and level in power steering is full. My question is this: does the gear box use power steering fluid or gear oil? I ran my hand directly over the area above the box and it is dry just in case something else is dripping onto the box. It appears that the fluid leak is originating from the top cap of the steering box. Thanks!
