I sure hope someone can help us.

We have a 1997 F250 heavy duty diesel.

Our latest problem is that the steering wheel will stick. When this happens the power steering goes. So far we have been able to get it unstuck.

The pump does not make any grinding noise or squeal of any kind. The fluid levels are good.

I would like to haul my horses but with this issue going on I am stuck.

Please help
