Lubing the HWH Jacks with what ?

I had one that needed the 2 x 4 treatment, and shortly after it started chattering, it locked in the down position. if yours starts chattering, I would suggest an immediate replacement.

WD-40 is a cleaner and water displacer, not a lubricant

Silicone spray is recommended by Power Gear

not sure what HWY says to use. check the manual.

Using ANY type lube just goes around the problem which is worn out inner seals. HWH jack cylinders are IMMERSED in ATF when retracted. The ONLY maintenance is to make sure the shiny piston is clean. If your HWH jacks retract slowly or you have to lever them completely up, then the odds are the inner seals are worn and rebuild or replacement is the CORRECT procedure. If cost keeps you from replacing the cylinders, then you have to go thru the clean and wipe routine 2 or 3 times a month. Your springs might need replaced, but to check for that is simple. If you can push on a jack with your hand and it fully retracts, you need new springs. If it takes extra force(lever) to retract, it is NOT your springs but the inner seals. Doug

I think you hit the nail on the head. The seals get a little on the dry side and if you extent them full and wipe them down with ATF, then retract while wet with ATF most times there good to go.

HWH jacks use ATF to lubricate. Do not use silicone unless you clean thoroughly with WD40 and wipe dry with a clean, dry rag.

Basic cleaning of the complete jack assembly is accomplished with the use of soap and water.
Spaying the jacks with a spray wand at a car wash would be acceptable.
The only time a jack rod would need cleaning is if the jack has been extended for a period of time.
The jack should not be extended just to clean the rod.
WARNING:
If the jack is extended, use soap and water or WD-40 on the jack rod then wipe the rod dry with a clean
cloth.
FORWARD OR BACKWARD WITHOUT WARNING CAUSING INJURY OR DEATH.
IMPORTANT: Do not use a dirty rag to wipe the jack rod or do not wipe the jack rod if it is coated with dirt.
This could scratch and damage the rod. Make sure to use water or WD-40 to loosen any dirt before
wiping the jack rod.
If the jack rod has been greased or silicone sprays have been used on the jack rod, use WD-40 to loosen
the grease or silicone and wipe the rod clean.

Another vote for transmission fluid. Once I started using this, they retract pretty fast. It is my understanding that the fluid in them is ATF.

Silicone lube is better then WD40. I have the Quadra Big Foot and they lube every time you raise the levelers. Each leveler has its own pump and motor. They are the best as far as I am concerned. I used to have on my gasoline motorhome hwh with spring returns. I just did not like them from the start. Within six months one spring broke. So the new gas coach had to go. Five thousand miles on it, but I was glad to get rid of it.
Best thing I could have done. I have had real good luck with the Gulf Stream Scenic Cruiser.

I don't think they are metal on metal....there's gotta be a seal in there someplace. My manual says to spray silicone and then wipe off. This is to keep the seals from getting gritty.

Mine got to a point that I had to use a 2 by 4 and I eventually tried WD-40 and ever since they come up. I spray each one just prior to storing them.
