I hear a winding sounding when driving on 1992 Chevrolet 1500 Pickup

I hear it more when I am slowing down

It could be many things, unfortunately and without hearing the noise first hand or being able to do some basic diagnostic tests or be able to drive the car, its hard to say what the source of the noise may be. What do you mean by "winding"? Can you locate whether the noise is front, rear, under the truck, or in the engine compartment?
I'm not sure right now I notice I have an oil leak now, so I'm going to look underneath the truck to see what's really going on,I hauled alot of wood the other week and that's when all of this started , to be continued.Thanks for your reply
