My Dynamax dynaquest 302ST RV is built on a 2010

This answer was rated:

My Dynamax dynaquest 302ST RV is built on a 2010 Freightliner M2 106 chassis. I noticed a puddle of power steering fluid on the concrete pad below the reservoir. It appears to be leaking from the hose that runs from the reservoir to the trw unit. Do I need a special Freightliner hose? What kind of power steering fluid do I need to replace any I lose while replacing the hose?
JA: What is the complete model and serial number of your machine?
Customer: 2010 Freightliner M2 106

Good evening
Yes sir you do
Be sure you use proper power steering suction hose, you don't need to get from Freightliner, but make sure you ask for the proper stuff.
Let me know if you have any other questions.

My leak is occurring at the upper end of the purple hose near hose clamp #6 - is there a part number or name for this hose?
Power steering suction line from resivor to pump.
Can buy in a section and cut to fit
Make sure clamps are replaced as wellUnable to get part number
But if you go to Freightliner, they will have it,

We are 120 miles from Freightliner - can I source the proper hose from an auto parts store?
Customer: replied 28 days ago.
What power steering fluid does Freightliner use? I assume I'll lose a couple of qts draining the reservoir.
Have a look at the color, if it's red then automatic transmission fluid or atf, if not then 15w 40 oil,
Good evening I see the question is still open Do you have any other questions?
