Whining When Turning

Folks, I know, I should search. And I did and got just about every answer I can think of. But my son is in a bind.

2007 CRV

He is about 750 miles from home. A week or so ago he started to notice a whining noise when turning. And he thinks more so when turning left.

He was planning to return two days from now. He took it to a shop last week and they said, no problem, $40/$50 to fix, bring it in Tuesday (today....like were they putting him against the wall?). Today they say $600.00.

Bottom line, is there a risk in driving 750 miles home?
Is there anything else to try.
Fluid is full. One hose was replaced two years ago.

Thanks in Advance

Worste case scenerio it the power steering pump siezes and he burns up the belt on the highway. Not a life threatening scenerio but could be expensive concidering tow and repair. I have had a power steering pump whine on my 01 dodge caravan for the past 2 years with no other problems I think he can get it home just fine because highway driving doesnt put alot of stress on the power steering system.

Thanks.
That is about what I figured.
But I had not considered the seize up.

I'll tell him to be sensitive to that and shut down ASAP.

But I concur, low probability.

Thanks again.

I'd keep some extra fluid on board in case he notices that it gets worse. It would suck to be stranded and need a tow when all you needed was a quart or two of fluid to get you to a safe spot.
