When the truck is warm it starts to make a sound like the power steering pump is low on fluid, but its not (a whine during low idle turning and braking). I'm 99% sure my pump is going bad, so unless someone disagrees that is not my question.....
The question is, would the power steering pump have anything to do with the trucks vacuum lines? For my auto locking hubs, when I put it into 4 wheel the pass hub gets like 5 lbs of vacuum and the drivers nothing... Is this another issue or possible related?
