So far I drained and filled my 2019 power steering unit twice.
not a lot of miles but I have 37 inch tires and we have kazillions of pot holes here in nyc.
not sure if it’s road wear, , debris left over from the manufacturing process, ir by product of my lift install tap and banging…but so far..during both drains…I’ve seen very very small particles …some shines some dull. On my list to do is to flush this system out . In the mean while…I installed a magnetic power steering unit filter.
the wheel well has extra square holes that easily takes one of those nut plate flat clamps so I installed it there. Took the return line off the revisor and put it on the filter in and put a new line from filter out up to the revisor. I started to reuse the existing clamp but the hose was able to rotate with the clamp on so I used those threading clamps instead.
so all in all, a filter, a section of hose, three thread-able clamps, a nut plate bracket and bolt…and it was done. It’s on the front side of the spring mounted on the frame.
I sought there will be particles on the next revisor drain… it this filter is going to get cut open to see what it captured.
I used to run these on my 96 F250 with the extra coolers on the truck in the transmission fluid circuit... I used my truck pretty heavy for snowplowing when I had it.

A turkey baster to suck out the fluid and Mercon LV is the ticket.
on my truck there is a plastic screen that blocks getting to the bottom of the revisor and most of the fluid is in the pump and very little in the revisor.
the best way to flush this out is to pull the return line , put a new short line on the revisor and block that new short line with a bolt. Take the original revisor return line and put it in an empty gallon jug. Have someone start the truck watchers ng your instructions…have them move the wheel slightly back and fourth….as you pour fresh new fluid into the revisor. Shut the truck off, too off, reassemble.
or if you have a Venturi vacuum setup… suck all the old fluid out thru the return line …let the vs use pull fresh new fluid back in.

I looked into the fluid circuit before and I believe there's a cooler inline... I've got stuff printed out that I have to look for... I know the return is low pressure, I believe, if I'm remembering correctly. I was just going to remove the low pressure return off the cooler, have my wife in the truck, start it and let the pump pump out the old fluid. When it starts spitting air, have her shut it off. I used to do that with my 96 plow truck. I had a two way valve on the return trans line after the coolers. I would have my wife get in, start it, go through the gears and let the trans pump do the work... as soon as it stopped flowing full and started to spit, she would shut it off. I did it twice when I did that... made the problematic E4OD last past 90k miles by doing that prior to every plow season...

There's many ways to skin a cat. My method right or wrong takes all of 5-10 minutes per drain/fill to perform with no mess. Out of curiosity I inspected the mercon in my PS reservoir this evening and it looks nice and bright red as if it was just out of the bottle. I didn't document when I changed the fluid in the reservoir, but I estimate it was ~4 years ago/~80k miles. I drained and refilled 2-3 times with a day's driving in between to allow the fresh fluid to circulate through the system. My PS system is smooth, quiet and I predict will last many years to come.

Yep... never meant a slight towards your method... I'm curious what mine looks like after 106k miles....
If this filter is so important why don't car manufacturers install them? I see so much snake oil being offered with placebo affects.
It's about the peanut counters. Why would the auto manufacturers want the power steering system to last longer when they have power steering pumps to sell or better yet, more new trucks? A guy like myself has a way different outlook on the paid off vehicle I now drive than Ford does... I want the parts to last longer so I do what I feel will make them last longer. End of story.
Besides, when I put one of those filters on my power steering system, it was on a truck that was snow plowing commercially... lots of turns and back and forth while pushing tons of snow... more hard use than a truck that sits and gets used randomly. With Fritz having those 19.5" oversized tires, that puts a lot of stress on the power steering system that was designed for the 19.5 inch stocker size tires.

also, the manufacturing goal is to have a truck that has a low cost to warranty. Ones don’t build trucks with the idea of key components need to last 10 years, etc.

I don't recall a plastic screen on my reservoir. Must be something Ford added on newer models.
