If your car is air bad equiped, the inflator for the bag has a slow leak. It should be checked and replaced.
it is unlikely to be your air bag if equipped as the inflator is a explosive charge not filled with fluid. the air bag system is mostly made up from electrical components , explosive components and the hardware that contains it all excluding the bag itself which is a porous cloth material. there are no fluid containing components in your steering wheel only a small amount of grease inside of the column to lubricate the steering shaft bearings.
Low fluid and dirty fluids.
Power steering fluid helps your steering wheel turn easily. If you have dirty power steering fluid, it may be hard to turn your steering wheel while driving.
first don't get power steering fluid on your clothes second get that stuff fixed
your pump could be low on power steering fluid, your power steering belt could have came off if equiped with a separate belt and finally the pump could have failed from low fluid, or dirty fluid
dirty oil in system not drained from previous pump
Flush it
Dark fluid means it's dirty and needs replacing.
you may need more power steering fluid.
Low Power Steering Fluid
Power steering box... Steering fluid level low,dirty or needs replacing... If power steering fluid is white then your box is damaged...
Air in a power steering system is caused by low fluid or a leaking seal. When the fluid is low, the pump becomes exposed to the air and causes large bubbles to form.
My mechanic told me every 2-3 years, depending on how dirty the fluid looks.
