HWH Jack Noise

[Lanny Shaw]

I have an issue with my HWH jacks. When I get to the RV park I do the air dump then start lowering the jacks to level the RV. When I do this there is a very loud whine emitted and I can't figure out where it's coming from. I don't know if it's the hydraulic pump or something else. It's so loud that we don't put the jacks down or slides out if we arrive at a campsite late in the day (we don't want to wake/disturb anyone with the noise). Does anyone have any helpful suggestions? Thanks.

Suggestions: check reservoir level. Next time fully extended lube each jack piston with T9https://www.amazon.com/BOESHIELD-Cor...573127605&th=1

Try manually lowering the jacks in different sequences. L/R, F/B,L/F,B etc.

check your jacks, one is making the noise. loosen the lower clamp slightly. the cylinder is supposed to be loose enough to turn within the clamp.
there is a groove cut into the cylinder that the clamp is supposed to fit into.
the upper and lower clamps both fit into grooves cut into the cylinder.
the jack will make a noise especially if the lower clamp is torqued too tight
