Question Power steering firm spots; time for a fluid flush?

My power steering has two distinct firm spots when turning lock to lock. I dont hear a noise but I can feel the spot in the steering wheel. The two firm spots are on either side of center the best I can tell. As the truck gets warm it seems to decrease and in summer is was not present. This leads me to believe it is fluid related.

I had a similar problem with my Mustang and flushing/changing the power steering fluid fixed it. The steering is much more responsive and smooth at all temperatures. That car is 10 years older but with same mileage.

Has anybody tried this on a Superduty? I tried the search but didn't turn up much.

I noticed all the local shops now offer a power steering service. Never heard of it until a few years ago.

Thanks

1. If it worked on the Mustang, probably work on the truck
2. At a minimum, I'd air bleed it, afterall, it is a hydraulic system, and air doesn't compress.

I had one in my shop that had tight spots in it. I ended up taking the tie rods off the spindle to turn the spindles by hand and the one side had a really tight lower ball joint.

Maybe not as well, but let me ask you something......Ever heard of an air compressor...Believe your thinking of water (which still compresses, just takes so much force it's considered not to).

Don't drink and forum, you'll end up typing some stupid crap like air doesn't compress.
