Power steering pump line (bleeding)

[TwoHuskies]

I have a 2020 Newmar/Freightliner and drove 500 without power steering. Painful. Took in to local Freightliner center and spoke with shop manager. Seems that when coaches are built, they put on a lift during assembly. RVs have a hydraulic ram that pushes the power steering fluid from the front steering column area to the back where the pump is located. During assembly, if the manufacturer doesn't bleed out the PS fluid by rotating the wheel fully (left/right) there will be air in the line. This air is known to burn out the pumps prematurely. My coach has 7000 miles. Seems like a known issue to Freightliner. No Comfort Drive and worse, no power steering!

All power steering is bled by turning steering wheel lock to lock....

No hydraulic ram on my FL XC Fleetwood unit.
Engine mounted PS pump (attached to back of air pump) with lines from reservoir up to steering box under chassis.
(I know all this as my power steering went out...and in troubleshooting and bleeding the lines)

Mine ended up being either a blocked passage in the pump or a bad pump. Replacement was $150 and an hour of my time.
